August Birthstone: Spinel Gemstone

By August 25, 2017All

Spinel is a good candidate for the title of “History’s Most Underappreciated Gem.” Some ancient mines that supplied gems for royal courts from Rome to China produced spinel, but it was usually confused with better-known stones like ruby and sapphire.

At Artisans Bespoke Jewellers, we love working with Spinels as they come in a variety of colors, in particular red and pink. Mauve- or lilac-colored spinels are also attractive, and some blue spinel colors can be intense.
