Red Spinel

Spinel is highly sought after by gem connoisseurs with crystals in high demand among collectors. Red spinel is the most desirable, followed by cobalt-blue spinel, then hot pink and vivid orange stones. The natural stone is often transparent and usually needs no treatment. Its ranking of 8 on the Mohs hardness scale makes it ideal for every type of jewelry.

Red spinel ranges from orangy red to purplish red, with pure red hues the finest. A top quality 5 carat red spinel might sell for a tenth the price of an equivalent ruby. Pink spinel often sells for less than pink sapphire. Prices for the highest quality have exploded in recent years.

The most highly valued blue spinel colors parallel blue sapphire, with intense violet-blue to pure blue colors highly regarded. Eye clean spinel is more valuable than that with inclusions. The more visible the inclusions, the more the value drops.

Larger spinel sizes rise considerably in per-carat price. Prices rise sharply for fine red, pink, and blue stones above five carats.
