Our Gemstones Guide

Did you know only four gemstones are classified as “precious”? Diamonds, rubies, sapphires, and emeralds are the only precious gemstones. The rest are classified as semi-precious. At Michael C Fina, we love gemstone jewelry and working with precious gems. While these gemstones can be found in a mineral shell, it’s still important to take great care of them to keep them in great shape. Check out our Gemstone guide where you will find more information on the history of each gemstone and how to care for your gemstone jewelry.
