Spinel crystal It is a precious gem of transparent red, darkish and yellowish red. Red color of spinel is so close to ruby that quite a few spinels were wrongly mistaken as rubies in the past. Ruby popularly known as ‘Black Prince’ among the jewels of the British Brown is not actually a ruby but it is a red spinel. Spinel is good for financial gains and protects the wearer against unforeseen losses.
