Through the ages, spinel has been one of the most misunderstood and under appreciated of gems. Spinels have very often been confused and sold as better known stones, like sapphire and ruby. Even the famous Black Prince’s Ruby, which has been a central stone in the British Imperial State Crown since the 1300s, is actually a magnificent 170ct red spinel.

Spinels limited availability is also a reason for its lack of public recognition. Spinel is difficult to find in sizes larger than 4ct. Spinel is often found alongside corundum and can be found in crystals, as well as waterworn pebbles in gem gravels. Spinels can range in color from violet, blue, purple, orange, pink, and red. Fine ruby-red spinels and deep rich blues are the most desirable colors. Spinel is a hard, tough stone that looks great and is suitable for daily wear in almost any type of jewelry.
