How Many Beads Are in 1 oz? A Quick Guide for Bracelet Making
At LUYURI, loose beads are sold by weight — 1 oz, 2 oz or 4 oz — instead of by the strand or by the piece. That keeps pricing simple and lets you mix stones freely, but it raises one very practical question before you order: how many beads are actually in an ounce? This guide gives you the numbers, plus how to turn them into bracelets.
Why bead counts per ounce vary
An ounce is a weight (28.35 grams), not a count, so the number of beads you get depends on two things:
- Bead size — the big one. A bead's weight grows with the cube of its diameter, so a 10mm bead weighs roughly eight times as much as a 5mm bead of the same stone.
- Material — natural stones have similar densities (quartz-family stones like amethyst, rose quartz and citrine are all close), while heavier stones such as hematite give you fewer beads per ounce, and glass or acrylic beads give you more.
Beads per ounce: the quick table
For natural stone round beads (quartz family), these are reliable planning numbers:
| Bead size | Approx. weight per bead | Approx. beads in 1 oz | Beads in 2 oz | Beads in 4 oz |
|---|---|---|---|---|
| 4mm | ~0.09 g | ~300 | ~600 | ~1,200 |
| 6mm | ~0.3 g | ~90 | ~180 | ~360 |
| 8mm | ~0.75 g | ~38 | ~76 | ~152 |
| 10mm | ~1.4 g | ~20 | ~40 | ~80 |
| 12mm | ~2.4 g | ~12 | ~24 | ~48 |
Counts are approximate. Natural variation in drilling and density means your bag may land a few beads either side of these numbers — that's normal for genuine stone.
So how many bracelets is that?
A standard 7-inch stretch bracelet (the most common wrist size) uses roughly:
| Bead size | Beads per 7" bracelet | Bracelets from 1 oz | Bracelets from 2 oz | Bracelets from 4 oz |
|---|---|---|---|---|
| 6mm | ~28 | ~3 | ~6 | ~12 |
| 8mm | ~22 | ~1–2 | ~3 | ~6–7 |
| 10mm | ~17 | ~1 | ~2 | ~4–5 |
Worked example: you want three matching 8mm amethyst bracelets for gifts. Three bracelets need about 66 beads. One ounce gives you roughly 38 — not quite enough — so the 2 oz option (about 76 beads) covers all three with a few spares for a keychain or a repair. That's exactly the kind of math buying by weight makes easy.
Planning tips
- Order a little extra. Patterns with accent beads, the odd bead that rolls under the couch, a bracelet for a slightly larger wrist — a small buffer saves a second order. The 2 oz size is the sweet spot for most single-stone projects.
- Mixing stones? Add each stone separately in the amount you need. Two ounces total split across three stones is a classic starter mix — build your own bead mix here.
- Bigger wrist? Add about 2 beads per extra half-inch of wrist size for 8mm beads.
- Glass beads run lighter. Expect roughly 10–20% more beads per ounce than the stone table above. Check the glass beads collection for colors that don't exist in natural stone.
The bottom line
Think of it this way: 1 oz samples a stone, 2 oz makes a small project, 4 oz stocks your bead box. With the table above you can plan any bracelet project before you order — and if you're deciding between sizes, our bead size guide shows what each size looks and wears like.
