SPINEL (spin-l) - Now an August Birthstone

Jessop ‘s One-of-a-Kind Red Spinel & Diamond Ring - SHOP HERE!

For centuries, many gemstones thought to be rubies used in crown jewels throughout the world actually turned out to be spinel. This initial confusion resulted from spinel’s resemblance to well-known stones like rubies or sapphires.

Spinel’s beauty and wide range of colors and cuts makes it deserving of appreciation and recognition in its own right. Designating spinel as an August birthstone is further proof of its importance in the gem world.

The most desirable and valuable spinel gemstones are vivid red, followed by cobalt blue, bright pink and bright orange. Vividly colored spinel gemstones are rare in sizes over 5 carats. Paler colors tend to be more affordable. Other colors found are black, violet-blue, greenish-blue, pale-pink, mauve, yellow and brown.

A good quality stone should have no visible inclusions; the more inclusions, the less valuable the stone. However, a rare but desirable inclusion would result in a star spinel. Spinel ranks 8 on the Mohs scale and has good toughness, making it a durable gem for jewelry.
