The Gemstone of Queens and Emperors

In the Middle ages, spinels were commonly mistaken and used in place of rubies in crown jewels.

The singly refractive flaming-vivid red spinels are striking enough to rival rubies’ supremacy. In fact, the world’s most famed one, namely “The Black Prince’s Ruby” is, as a matter of fact, NOT a ruby at all, but you guessed it, a red spinel! The grand, semi-polished, crimson octahedron sits at the fore part of Britain’s Imperial State Crown. Around the mid-1700s, scientists and dealers of the field came to the discovery that spinel and ruby were two distinct minerals. Both contain aluminium, oxygen and chromium but spinels also have magnesium.

Hard and tough for everyday wearability

In our universe, usability and longevity matter immensely. The resistance levels of a rock’s ability to endure scratching is referred to as “hardness”. The “Mohs hardness scale” is the parameter to consult on this topic. A high attribution signifies a gem’s potential to withstand abrasion, and spinel has a hardness of 8 out of 10. They are also very tough, so suited for everyday worn pieces!

Mesmerising Crystals and Amazingly Brilliant

One more thing that makes spinels very special are their beautiful crystals. Just like with diamonds, spinels frequently form perfect octahedral crystals. This three-dimensional shape resembles a couple of four-sided pyramids attached at their bases.

If you do happen to already be in the possession of a spinel, try placing it under a light. Granted, you will be dazzled! The immense brilliance you should be able to witness is actually a reflection of the light off of its surface: the measure of quality and intensity we refer to as “lustre”.
