Both, the Spinel and the Ruby have exceptional hardness as a result, they have incredible lustre. Key to telling the difference back in the day, lustre spoke multitudes without much gemological advancement.

Properties of a Spinel

Spinels naturally form in the Cubic Crystal structure, often appearing as sharp crystals or as tumbled stones. This led to its name perhaps originating from the Latin word Spina meaning thorn. Filled with rich colour that will distract the viewer from any other feature, the Spinel instantly transforms any piece of jewellery adding both grandeur and style. 

With red carpet colours resulting from the alteration of Magnesium and Aluminium, Spinels commonly come in lighter toned reds, purples, violets and even fainter blues. For example, the Reds get their colour because of Low levels of Aluminium which is replaced by Chromium. The cooler toned Blues, on the other hand, get their colour because elements like Iron, Titanium and Zinc replace Magnesium.

Intermittently set together with Diamonds and Sapphires, these royal tinted gems pair well together and do not easily abrade each other.
