The Complete Guide to Edible Glitter and Luster Dust
Knowledge Hub · Edible Glitter & Luster Dust
Everything a decorator needs to know about mica-based edible shimmer: what it's actually made of, how glitter differs from luster dust, how to use each one, and how to tell genuinely edible sparkle from the kind that isn't.
Quick answer
Edible glitter and luster dust are made from the same core ingredients, mica-based pearlescence pigmented with FD&C food colorings, but they're built for different jobs. Glitter is a fine flake made to scatter into drinks or over finished food, where it stays suspended and catches light. Luster dust is a powder made to brush, paint, or airbrush directly onto a surface for a solid metallic sheen.
What glitter and luster dust are actually made of
Both come from the same two ingredients: mica-based pearlescence for the shimmer, and FD&C food colorings for the shade. Mica is the mineral that catches and reflects light. In DiamonDust and Sterling Pearl, it's a synthetic mica sourced from a raw ingredient supplier in the United States, not mined. It's also insoluble, which is why it stays suspended in a drink rather than dissolving into it.
The grind is what actually separates the two products. A finer, flake-cut grind scatters and catches light in liquid or over a finished surface, that's glitter. A softer, powder-fine grind is made to be brushed, painted, or airbrushed directly onto a surface, that's luster dust. Same core chemistry, different job.

Glitter or luster dust, which one do you need?
If you're finishing a drink, a glaze, or want shimmer that moves and catches light, reach for glitter. If you're covering a solid surface, fondant, chocolate, a cookie, with an even metallic sheen, reach for luster dust.
That covers the decision most decorators are actually making. For the full breakdown, including gum-based glitter and where gold leaf fits in, see our complete comparison of edible glitter and edible luster dust →
Using edible glitter
Add a small amount directly to a drink or scatter it over a finished dessert. In liquid, the shimmer stays suspended rather than dissolving, so it keeps moving every time the drink is stirred. Lighter colored drinks show it best. It's tasteless, so it changes how something looks without changing how it tastes.
Using luster dust
Brushed on dry, it gives a soft, powdery sheen. For a painted metallic finish, mix a small amount with a clear high-proof alcohol or lemon extract, both flash off and leave the pigment behind. For airbrushing, thin it further. Build depth with more product rather than working it harder into the surface.

Is it actually edible?
Genuinely edible glitter and luster dust carry three things on the jar: a full ingredient list, an expiration date, and a lot number. All three are FDA requirements for food. Every DiamonDust and Sterling Pearl jar carries all three, and both lines are FDA compliant and made in the USA.
Anything labeled decorative use only, or that avoids the word edible entirely, is not food and should not be eaten. That's the one thing worth checking before you buy, on any brand.
✓ FDA compliant
✓ Made in the USA
✓ Lot number + expiration on every jar
A few things worth knowing before you start
- ✦ Use more product for depth, not more pressure. Working luster dust harder into a surface doesn't deepen the color, more product does.
- ✦ Color reads differently wet versus dry. Let a painted luster dust finish dry fully before judging the shade.
- ✦ The shaker top on DiamonDust is proprietary to The Sugar Art, the logo is molded into the closure itself, built to control how much comes out at once.
- ✦ Not every shade is available in both formats. Check the individual product page for the exact ingredients and format.
Frequently asked questions
What is edible glitter made of?+
Edible glitter is made of mica-based pearlescence pigmented with FD&C food colorings. The mica creates the reflective, light-catching sparkle, and the FD&C colorants provide the shade. DiamonDust is FDA compliant and made in the USA. Exact ingredients vary by color, so check the individual product label.
Where does the mica in edible glitter come from?+
The mica in DiamonDust is not mined. It's a synthetic mica sourced from a raw ingredient supplier in the United States. Mica is the mineral that creates the reflective, light-catching quality in edible glitter, and it's what makes the shimmer hold in liquid rather than dissolve.
Is edible glitter safe to eat?+
Yes. Glitter that is genuinely edible carries three things on the jar: a full ingredient list, an expiration date, and a lot number. All three are required for food. DiamonDust carries all three and is FDA compliant and made in the USA. Anything labeled decorative only is not food.
What is luster dust?+
Luster dust is an edible powder that gives a soft metallic or satin sheen to cakes, cookies and chocolate. It's mica-based pearlescence pigmented with FD&C colorings, a powder you brush or paint on, rather than a flake you scatter.
How do you use luster dust?+
Brush it on dry for a soft, powdery sheen. For a painted metallic finish, mix a small amount with a clear high-proof alcohol or lemon extract, which flashes off and leaves the pigment behind. For airbrushing, thin it further. Use more product for depth rather than working it harder into the surface.
How do I use edible glitter in drinks?+
Add a small amount of DiamonDust to the glass and stir. The shimmer stays suspended in the liquid rather than dissolving, so it keeps moving as the drink is stirred. Lighter colored drinks show it best. DiamonDust is tasteless, so it changes how a drink looks without changing how it tastes.
Where can I find pink edible glitter?+
Pink edible glitter is sold as Strawberry DiamonDust at The Sugar Art. Its soft, light red tone works beautifully in pink and red icings, cookies and drinks.
What is black edible glitter?+
One of the lines created at The Sugar Art specifically for cake decorators and cookie artists, a unique homogenized blend of mica-based pearlescent food coloring, giving you the deepest darkest black glitter on the market.
Where can I buy edible glitter and luster dust?+
Direct from The Sugar Art, where it's made. We ship to all fifty states and internationally. Buying direct means the full DiamonDust and Sterling Pearl range is in one place, and every jar carries its own lot number and best-by date from the facility that produced it.
Which edible glitter brands are actually food safe?+
Check the jar, not the brand name. Genuinely edible glitter always shows a full ingredient list, a lot number, and an expiration date, the same three things any food product has to carry. If a product is labeled "non-toxic" or "for decorative use only" and skips the ingredient list, it isn't food, whatever the packaging implies, non-toxic only means it won't hurt you in a trace amount, not that it's cleared to eat. With thirty years of experience as pioneers in edible glitter, The Sugar Art is recognized as the industry standard, because we use only the highest-grade food colors allowed by the FDA and meet every standard required to stay compliant.
Is luster dust edible or not?+
Not all luster dust is edible. What to check is the label: a full ingredient list, a lot number, and an expiration date, those are the real indicators of whether a product is actually edible. The words "non-toxic" or "for decorative use" on their own mean the product is not compliant for food use, whatever the packaging implies, and it shouldn't go on anything you plan to eat. Sterling Pearl luster dusts from The Sugar Art carry all three on the label.
Does gold edible glitter contain real gold?+
No, there's no metal in it. Gold edible glitter gets its color from an interference color: mica-based pearlescence naturally refracts light back in the yellow-red part of the spectrum, so the gold comes from how light bends off the mica, not from a pigment or a metal. Blended with FD&C food coloring through The Sugar Art's proprietary process, that's what gives DiamonDust its gold hue and shine. True edible gold, gold leaf, is a separate product in its own category, if that's specifically what you want, look for it by name.
What's the difference between edible glitter, luster dust, and sanding sugar?+
Edible glitter and luster dust are virtually identical, both mica-based pearlescence pigmented with food coloring. The real difference is particle size: glitter is a larger, flat flake that creates visible sparkle, luster dust is a much finer powder that gives an all-over sheen instead. Sanding sugar is a completely different product, crystallized sugar that's been pigmented or spun/colored, coarse and crunchy rather than a shimmer finish. Whichever one you're using, check the label before buying any of them: a full ingredient list, a lot number, and an expiration date confirm it's actually food-grade.
What's the difference between luster dust and petal dust?+
Luster dust is mica-based pearlescence, an interference color that refracts light, combined with powdered food coloring, that combination is what gives it a metallic sheen. Petal dust is pure powdered food coloring with no mica, designed for a matte finish whether it's painted on or dusted. A third category, disco dust, looks similar to both at a glance but is usually not food-grade, made of larger reflective particles meant for decorations removed before the piece is eaten.
What's the difference between petal dust and powdered food coloring?+
Petal dust is a fat-dispersion powdered color, made to work in chocolate or dusted onto confections to build a color gradient. Powdered food coloring can also be water-dispersion, meant to mix into water-based ingredients like cake batter, royal icing, and macarons, Master Elite Icing Powders are an example of that kind. The dispersion type is what actually determines where each one works, not just how it's applied.
Can you make your own luster dust?+
No, not really. Luster dust is produced in an FDA-registered facility, using specialized equipment and ingredients that aren't something you can replicate at home. What you can do instead is make sure what you buy is genuinely edible: check the label for a full ingredient list, a lot number, and an expiration date. Anything marked non-toxic or for decorative use only isn't food-grade, no matter how it's marketed.
Does edible glitter glow under blacklight or UV light?+
No. There's no genuinely edible glitter that glows under blacklight or UV light. If a product is marketed as glowing in the dark, treat that as a sign it's not edible, glow-in-the-dark effects come from a different, fluorescent ingredient, not the mica-based pearlescence real edible glitter is made from. What edible glitter does under any light, including blacklight, is reflect and scatter it, which can still look striking under UV party lighting even without true glow.
Is edible glitter a choking hazard for young children?+
Edible glitter is generally composed of 150 to 250 micron mica-based pearlescence, a particle size that should not pose a swallowing hazard. That's a separate question from ingredient safety, which comes down to the label: a full ingredient list, a lot number, and an expiration date confirm a glitter is genuinely edible, regardless of particle size.
Does edible glitter come in a spray, and how do you use it?+
Yes. DiamonDust comes in a large spray bottle as well as the smaller shaker jars, in White Diamond, Gold, Silver, Rose Gold, and Rainbow. It's a dry-powder spray, not a liquid one: press the bottle, and the cap's internal baffles open to release a fine, even mist of glitter, no liquid or propellant needed. Hold it a few inches back and use a light, even pass over a drink, a dessert, or a finished cake; add a second pass rather than starting heavy.
How much edible glitter do you need to cover a cake?+
There's no fixed amount, and that's really the more useful answer. Edible glitter is meant as an accent, not a blanket coating, and it makes its biggest visual impact applied intentionally to specific areas, an edge, a drip line, a cluster, rather than spread evenly over the whole surface. Applied too heavily or too broadly, it actually loses that eye-catching effect instead of strengthening it. If you're planning a heavily glittered multi-tier design, buy one jar first and test the look on a single tier before ordering for the rest, how far it goes depends more on how you apply it than on how big the cake is.
How do you get edible glitter to stick and stay on a cake?+
Moisture is what makes it stick. Applied to a surface that still has some give, buttercream, for example, while it's not fully dry, edible glitter bonds to the surface on its own. Applied to something bone dry, like fully cured fondant, it can flake off just as easily as it went on. If the surface has already set, brush on a thin layer of piping gel first to bring back some tack, then apply the glitter with a soft brush rather than pressing it in, pressing knocks more loose than it sets. Placement matters too: applied to the top of a cake, glitter holds far better than on the sides, gravity works against you there no matter how tacky the surface is.
How do you get edible glitter to stick to chocolate?+
There are two ways that actually work. Applied before the chocolate fully sets, while it's still soft, glitter presses in and stays permanently affixed once the chocolate hardens around it. On chocolate that's already set, use a binder: paint a thin layer of The Sugar Art's Color Solution over the surface, let it sit a few seconds until it's tacky rather than wet, then sprinkle the glitter on. The gums in the Color Solution act as a temporary edible glue, holding the glitter in place.
How do you apply edible glitter to fondant?+
There are two good windows to apply edible glitter to fondant. The first is while the fondant is still fresh and slightly tacky, before it fully sets, apply it then and it holds on its own. The second is right after pulling a piece out of the refrigerator: the light surface moisture from coming back to room temperature gives the glitter something to grab onto. Outside of those two windows, on fondant that's already fully set and dry, a light brush of water or edible glue first will do the same job, just use it sparingly since too much can dull the fondant's finish.
How do you apply luster dust to fondant?+
Luster dust is typically applied by painting: mix it with The Sugar Art's Color Solution to create a liquid paint, then brush it on as an accent. You can also dust it on dry, using a fluffy brush over different elements, for a softer, all-over sheen instead of a defined painted accent.
Can you mix edible glitter into frosting?+
Technically yes, but you won't get the effect you're after. Edible glitter is an interference color, meaning it needs light hitting it to create its sparkle. Mixed into frosting, it's surrounded on all sides instead of exposed, which blocks the light it needs and mutes the refractive effect the product is built around. For the shimmer look, apply it topically: pipe or spread the frosting first, then dust or brush the glitter onto the finished surface while it's still slightly tacky.
Can you put edible glitter inside cake batter?+
Edible glitter itself holds up fine in the oven, its composition withstands heat whether it's on the surface or mixed in. The real problem is light, not heat: baked into the batter, the glitter is fully surrounded, and light can't reach it to create the sparkle, the interference effect the product depends on. So you won't get a glittery interior, more a faint cloudiness at best. For a sparkly reveal when the cake is cut, color the batter itself for a visual surprise, then add the glitter to the exposed, cut surfaces or the outside finish afterward, where it can actually catch light.
What's the best brand of luster dust for gold and silver?+
Technique matters as much as the brand: work on a smooth, fully dry surface, mix the dust with a fast-evaporating carrier like Color Solution to a thick rather than watery consistency, and build the color in two or three light coats instead of one heavy one. Beyond technique, pigment purity is what actually separates a strong metallic dust from a weak one, some products stretch it with fillers like cornstarch or maltodextrin, which is what mutes the shine. With thirty years of experience, The Sugar Art is generally recognized as the premier food color maker in both edible glitter and luster dust; our proprietary color blends and production process are built to avoid exactly that kind of dilution.
Does a cake made ahead with edible glitter lose its sparkle in the fridge?+
No. Edible glitter and luster dust are insoluble mica-based pearlescence, so refrigerating or freezing a finished, decorated piece doesn't cause it to lose its shine or luster. If you're prepping ahead, a simple precaution still helps: cover the piece loosely rather than sealing wrap directly against the decorated surface, and let it come back to room temperature before unwrapping, so any condensation from the temperature change lands on the wrap instead of the cake.
Why does luster dust rub off on your hands after it dries?+
Luster dust is insoluble mica-based pearlescence bonded to food coloring, and it isn't meant to be a water-soluble product. Because of that, it doesn't absorb into a surface, it only adheres to it, so any friction, touching, rubbing, handling, can dislodge or displace it. How it was applied affects how much: dry-brushed dust sits as loose pigment held mainly by static and surface tack, and transfers more easily. Painted on, mixed with a small amount of fast-evaporating alcohol first, it dries into a thinner, more locked-down layer that holds up far better to handling. For anything that's going to be boxed or shipped, the painted method is the more reliable choice.
