Calibrated Gemstones and Diamonds in Calibrated Sizes

All Our Diamonds & Gemstones Are Natural.
When you order calibrated gemstones, or diamonds in calibrated sizes, each stone matches the others in color, clarity and dimensions. It's a perfect solution for jewelry designs in which the stones need to look exactly the same.

Our calibrated inventory includes quantities from pairs up to hundreds of matching diamonds, sapphires, emeralds and rubies. Each and every stone is specially selected by our jewelry experts to make sure they look exactly right in your jewelry creations.
