Table of Properties

Quick Guide

STR = Structure
HRD = Hardness
SG = Specific Gravity
RI = Refractive Index
DR = Double Refacting or Birefraction

The way this search works is that every gem and it's respective RI has it's own row. So if a gemstone has an RI range of 1.57-1.60 there will be an entry for 1.57, 1.58, 1.59, and 1.60. I made it this way because it was quick and easy to create. If this page get's some love, then perhaps I will make an easier user interface.

An example search may be for the RI of 1.54. Type: 1.54 into the search box and see the results as you type. You could also type: quartz and see what it returns. (If you are on a mobile device, your virtual keyboard may be hiding the results.)
