We love the majestic properties of Spinel. They're often an overlooked gemstone, but just like sapphires, spinels are available in almost all the colors of the spectrum. They can be red, orange, yellow, green, blue, violet or purple. Red is usually the most desirous color, but we love the pinks, oranges and steely purples.
Luster is the intensity and quality of light that is reflected from the surface of a gem. The luster of a polished Spinel is only exceeded by diamond, sphene and zircon.
The Spinel is graded an 8 in Mohs hardness scale, making it at the top of the list recommended for durability. We have a number of spinel engagement rings, which has become an increasing popular choice in recent years.
Some specimens of Spinel contain a network of thousands of “needle-shaped” crystals of rutile that reflect light from specific directions. In some specimens of spinel, these reflections produce a six-ray star when the gem is cut in cabochon. These phenomenal gems are known as Star Spinels.
