Frequently Asked Questions (FAQ) / Gemstone Measurement

Most of your gems have measurements like 6 x 4 x 3 mm. But I notice some have only one or two measurements, such as 5 mm or 6 x 3 mm. Why is that?

The measurements we provide are intended to represent a gemstone's length, width and depth (L x W x H) in millimeters. For many shapes, 3 measurements are needed to ensure a gemstone will fit a jewelry mounting.

For example: An oval 6 mm x 4 mm x 3 mm gemstone, would be 6 mm in length, 4 mm in width, and 3 mm in depth.

For round or square gems, only two measurements are needed since the length and width are the same (or very close). So 6 mm x 3 mm for a round or square gemstone, would indicate that6 mm is the diameter or length/width, and the second 3 mm measurement refers to the depth.

For many, the depth is not so important, so some gems may be summarized with only the length/width or diameter measurement; i.e., a 5 mm round / square gemstone).
