Spinel possesses magnificent gem quality and characteristics. Its resplendent
brilliance has made it long being mistakenly identified as ruby and sapphire until
mid-1800’s.
From ancient Rome to China, spinel has been one of the favourite gemstones
among Royal collections in the world. The legendary 170-carat Black Prince
Ruby set on the Imperial State Crown of England and the famous Timur Ruby
are distinguished examples known to the world. In Qing dynasty, the headwear
of court officials were inlaid with spinels; the 398-carat ruby-red gem that tops
the Imperial Crown of Russia is by far the largest spinel in the world.
Spinel is single refractive just like diamonds. It ranks 8.0 on the Mohs scale and
its toughness is good and durable enough for making jewellery. Spinel comes
in a variety of vibrant colours, ranging from red, pink, blue, purple to green. Top
quality spinel is usually without visible inclusion. When cut just right, it will emit
a lively and dreamlike sparkle which makes it highly mesmerizing.
Today, spinel is no longer standing in the shadow of ruby. Fine quality spinel
is hard to come by in size above five carats. This beautiful, rare stone with a
checkered history is highly irresistible to all gem connoisseurs.
