You have chosen your stones; now comes the size question. A crystal bracelet in 6 mm beads and one in 10 mm beads do not look, count or weigh the same, even on the same wrist. This guide gives you the number of beads and the approximate weight for each wrist size and bead size, using the same figures as our crystal bracelet builder.
What bead size should I choose for my wrist?
As a rule of thumb: 6 mm for a small or delicate wrist, 8 mm for most wrists, 10 mm for a larger wrist or a bolder look. There is no wrong answer, though. Bead size is first a question of style: 6 mm reads as discreet and easy to stack, 8 mm is the classic everyday size, and 10 mm makes each stone stand out, with its veins and colours clearly visible.
- 6 mm: fine and light, ideal for small wrists, for stacking several bracelets, or for children’s and teen sizes.
- 8 mm: the most common size, balanced on almost every wrist, for women and men.
- 10 mm: generous and visible, often chosen for men’s bracelets or to show off a striking stone.

How do I measure my wrist for a bead bracelet?
Wrap a soft tape measure around your wrist, just above the wrist bone, snug but not tight, and read the figure. No tape measure? Use a strip of paper or a piece of string, mark where it overlaps, then lay it flat against a ruler.
- Measure the wrist you will wear the bracelet on, at the place you will wear it.
- Keep the tape flat against the skin, without squeezing.
- Choose the bracelet size closest to your measurement.
- For a looser fit, take the next size up.
Large beads take up more room on the inside of the bracelet, so a 10 mm bracelet feels slightly tighter than a 6 mm one of the same length. If you hesitate between two sizes with 10 mm beads, the larger one is usually the more comfortable choice.
How many beads are in a bracelet?
Divide the bracelet length in millimetres by the bead diameter: a 16 cm bracelet holds 27 beads of 6 mm, 20 beads of 8 mm or 16 beads of 10 mm. The table below gives the count for every size offered in our builder, rounded to the nearest whole bead.
| Wrist size | 6 mm beads | 8 mm beads | 10 mm beads |
|---|---|---|---|
| 14 cm (5.5 in) | 23 | 18 | 14 |
| 16 cm (6.3 in) | 27 | 20 | 16 |
| 19 cm (7.5 in) | 32 | 24 | 19 |
| 21 cm (8.3 in) | 35 | 26 | 21 |
| 23 cm (9.1 in) | 38 | 29 | 23 |
More beads also means more room for combinations: with 6 mm beads you can repeat a pattern several times around the wrist, while with 10 mm beads each stone counts.
How much does a crystal bead bracelet weigh?
From about 6 grams for a small 6 mm bracelet in a light stone to more than 60 grams for a large 10 mm bracelet in hematite. Weight depends on three things: the number of beads, their diameter, and the density of the stone. Doubling the bead diameter multiplies the weight of each bead by eight, which is why a 10 mm bracelet is so much heavier than a 6 mm one.
We calculated the weights below from the mineral density listed in each stone’s data sheet, for three typical stones: obsidian (one of the lightest, density about 2.35), rose quartz (representative of the quartz family, about 2.65) and hematite (one of the heaviest, about 5.3).
| Wrist size | 6 mm | 8 mm | 10 mm |
|---|---|---|---|
| 14 cm (5.5 in) | 6 / 7 / 14 g | 11 / 13 / 26 g | 17 / 19 / 39 g |
| 16 cm (6.3 in) | 7 / 8 / 16 g | 13 / 14 / 28 g | 20 / 22 / 44 g |
| 19 cm (7.5 in) | 9 / 10 / 19 g | 15 / 17 / 34 g | 23 / 26 / 53 g |
| 21 cm (8.3 in) | 9 / 10 / 21 g | 16 / 18 / 37 g | 26 / 29 / 58 g |
| 23 cm (9.1 in) | 10 / 11 / 23 g | 18 / 21 / 41 g | 28 / 32 / 64 g |
These weights are approximate. They are calculated for solid spheres; real beads are drilled, so they weigh slightly less, and the elastic cord adds less than a gram. Porous stones such as lava rock are much lighter than their density suggests.
For comparison, a light wristwatch weighs around 30 to 50 grams. A 6 or 8 mm bracelet in a quartz-family stone is light enough to forget you are wearing it; a 10 mm hematite bracelet has a noticeable, reassuring heft that some people love and others find too heavy for every day.
Which bead size suits men’s bracelets?
8 mm and 10 mm are the most popular sizes for men, with 10 mm the usual choice for wrists of 19 cm (7.5 in) and above. Matte or dark stones such as hematite, obsidian, lava rock or tiger’s eye are frequent choices in those sizes. That said, a 6 mm bracelet worn alongside a watch is a discreet option many men prefer.
Can I mix bead sizes in one bracelet?
Not in our builder: each bracelet uses a single bead size, which keeps the circle regular and the count exact. To combine sizes, the simplest option is to stack two bracelets, for example a 10 mm bracelet with a 6 mm one in a matching stone.
See your bracelet in every size before choosing
In the crystal bracelet builder, you choose your wrist size and bead size, then add real stone photos one by one. The builder counts the beads for you and shows the price as you go. Hesitating between 8 and 10 mm? Try both before you start: the bead count and the price update as soon as you change size.
