Quantities and Measurements:
Most findings are packaged by weight. Although we use very accurate counting
scales and trays, small variations in each item mean the actual count may
vary slightly over or under the marked quantity. We strive to put the exact
amount in each bag, although +/- 5% is the standard in the jewelry supply
industry. At 5%, a 1 Gross bag could vary over or under by 7 pieces. If
it's short more than that, we'll gladly make up the difference. You can
expect a bag marked "1 dozen" to contain exactly 1 dozen.
1 Mass is 1,200 beads. (The weight and size don't matter.) A mass is the
standard unit of measure for many glass bead manufacturers. Since little
or no repackaging is needed, we can offer a substantial discount for masses
of many beads. We don't ship partial masses at the mass price. If a full
mass is not available, it may be 3 to 6 weeks before we can send the full
1,200 beads. Mass discounts are available for 1,200 of one color of one
bead, not for assortments.
Quantity... 1GR = 1 gross = 144 pieces / 72 pair / 12 dozen
1/2GR = 72 pieces / 36 pair / 6 dozen
Mass = 1,200 beads of the same color, size and shape
Weight... 1 Ounce = 28.35gm (grams)
1 Troy Ounce (ozt) = 31.1 grams (ozt are used for precious metals)
1 Kilo = 1,000 grams (or twenty 50-gram bags)
Size... 1mm = approximately 1/16"
1 inch = 2.54cm (centimeters), or 25.4mm (millimeters)
1 meter = 1.1 yards, 3.3 feet, or 39.4 inches

beads for the space it uses.
