Grey Spinel


Grey Spinels can range in color from a gunmetal grey to a steely grey to a deep charcoal grey. Many times a slight secondary purple or blue tone will add a little extra charm to the gem.

Currently this is one of the most popular colors and it feels like Grey is the new Black!

Spinel is the new birthstone for August, together with Peridot.

For centuries Spinels were confused with Rubies and Sapphires, especially since they are found in many of the same sources.

One of the most famous gemstones in the world, the ‘Black Princes Ruby’ in the Crown Jewels of England is actually a Red Spinel!

Notable sources of Grey Spinel include Burma, Tanzania and Sri Lanka.  

Spinel is a durable gemstone with a hardness of 8 on the Mohs Scale and can easily be used in all types of jewelry.

Spinel also celebrates the 22nd anniversary and comes in a wide variety of colors, giving lots of options for August!
