6.5 MM ROUND WHITE CUBIC ZIRCONIA - GRADE AAAAA - LOT OF 2

A: Hi Roger! I'm glad you asked this question. A lot of people new to jewelry making and gemstones reach for their desk ruler when they want to measure a stone, but the short answer is that you cannot measure a stone accurately using an ordinary ruler. You need a millimeter gauge. You can buy fancy digital gauges but I find that a simple brass millimeter gauge serves the purpose and is inexpensive. I have a tutorial on how to use a brass millimeter gauge. Just copy and paste this link into your browser. Always measure the depth of the stone as well as the length and width.
