I recently picked up a number of crystals and am unsure what the size designators are on the tags. Many of them have two numbers like this example. Would these numbers refer to lignes? The crystal is about 40mm in diameter. Thanks!

Jack

Jack,

The top number refers to the diameter in lignes. The bottom number refers to the curvature in height. Click on the following link for a more indepth discussion of this topic
