Rhinestone listings are chaos. Every shop uses a different measurement, a different unit, sometimes a different currency. Two listings can look completely unrelated and actually be priced within pennies of each other per stone.
This guide gives you the math in your head so you can glance at any listing and know whether it is a good price.
The three ways rhinestones get sold
By piece count. "ss16 crystal AB, 1,440 pieces, $12." This is the easiest. Divide the price by the count. 12 / 1,440 = $0.0083 per stone.
By weight. "ss16 crystal AB, 50 grams, $9." The shop should list an approximate stone count per gram on the product page. Use that count to work out your per-stone price. If they don't list a count, message them.
By gross. A gross is 144 stones1. "ss16 crystal, 10 gross, $14.40" means 1,440 stones at $14.40, or $0.01 per stone. Older shops and wholesale sites still use this unit, so it pays to know it.
Shortcut. Whatever the listing says, your job is to get to one number: price per single stone. Scout does this automatically so you don't have to do it at checkout every time.
Why weight-based listings are tricky
Stones per gram is not a universal standard. The count changes depending on the manufacturer, the specific color, and the finish. Metallic finishes weigh slightly more than plain crystal. Even within the same size, one shop's "ss16 at 30 stones per gram" can differ from another's.
Reputable shops publish an estimated count on the product page for any weight-based listing. If a shop sells by weight without giving you any count estimate, that is a red flag.
Red flags in listings
No size shown. If a listing doesn't specify ss size or mm, skip it. You'll get something you didn't expect.
"Mixed sizes" when you need one size. Fine for art projects, useless for a grid fill.
Weight only, no count estimate. Covered above. If the shop makes you guess the count, they are not confident either.
Stock photos without flash detail. If every color looks identical, the actual product quality might vary a lot. Look for shops that photograph each color individually.
Shipping math
The price per stone lies when shipping is a factor. A shop at $0.007 per stone with $12 flat shipping is more expensive than a shop at $0.009 per stone with free shipping over $50 if your order is around $40.
Run the total cost for your whole order on every shop you're comparing. Scout's price comparison factors this in when you're checking out.
Currency gotchas
Some shops are Canadian or European. Their price in CAD or EUR looks lower than USD at first glance but may not be cheaper after conversion. Scout auto-converts to USD so you see apples-to-apples numbers.
Quick recap. Divide until you get price per single stone. Watch for shipping, currency, and fuzzy listings. The math is always doable if the shop is being honest about what they're selling.
