Precious metal sheet and wire are sold by the troy ounce (abbreviated ozt). There are 31.1 grams per troy ounce, compared to 28.3 grams per conventional ounce. Why? The troy ounce originated in the Middle Ages, in Troyes, France, and became the traditional unit for weighing precious metals. The majority of our precious metal sheet and wire are cut by hand, so you may receive a bit over or under the number of troy ounces that you order, but rest assured, we do a final verification of the weight, and charge for the actual amount that is shipped to you.

  • Measure wrist circumference with a flexible measuring tape or string.
  • In the United States, the average wrist size for women is about 6-6.5", and the average chain or strung bracelet size is 7".
  • For men in the US, the average wrist size is a bit over 7", so the average men's chain or beaded bracelet size is about 8".
  • If in doubt, size up, especially if the bracelet must slide over the hand, or if stringing large beads.

When making your own custom-length rivets out of wire or tubing, the standard rule (so you can properly finish both ends) is to measure the total thickness of the items to be joined, and then add the wire (or tubing) diameter. See Riveting 101 for more information about making and setting your rivets or eyelets.

The ideal Crafted Findings rivet or eyelet length is approximately 1mm (1/32" - 1/16") longer than the total thickness of the pieces you are riveting. If in doubt (textured metal, imprecise measurements, etc.), it's safest to use an eyelet that is a bit too long, rather than one that's a bit too short. Assortments are a great way to get started. Then, if you need more of a specific size, measure that size before you run out, and follow up by ordering specific lengths as needed.

This reference chart is a rough guide to help you decide which rivet or eyelet lengths are likely to work best for new projects.

Quick References for Round Beads

How many beads do you need, to create the necklace you are designing? This chart details how many 3mm, 4mm, 5mm, etc. round (or cube) beads it takes to create a 16", 20", 24" or 36" strand. If you want to create an 18" necklace using a 16" strand of gemstones, you're in luck! The clasp and finishing findings will take up approximately 1" (depending on the size of your clasp, and how you finish your necklace), so now all you need is approximately 1" worth of spacer beads! Popular spacer bead options include glass seed beads, Swarovski crystal beads, small sterling silver beads, small gold-fill beads and base-metal heishi, disk beads, and small cubes.
