Balas ruby
Definition
A rare variety of spinel of rose-violet or pale red color, utilized as a gemstone in luxury jewelry. Structurally, this crystal differs from a natural ruby through its chemical composition based on aluminum and magnesium oxide, historically called 'balas ruby' due to the frequent confusion made in antiquity between the two minerals.
