Spinel: A Gemstone Worth Knowing

Spinel is a gemstone that often gets overshadowed by more well-known stones like ruby and sapphire. However, it is a gem in its own right, with a stunning range of colours and unique properties.

What is Spinel?

Spinel is a mineral composed of magnesium aluminium oxide (MgAl2O4). It has a cubic crystal structure and is typically found in metamorphic rocks. Spinel is a relatively hard gemstone, ranking 7.5 to 8 on the Mohs scale of hardness, making it suitable for various types of jewellery.

The Characteristics of Spinel

Colour

The colour of spinel is the most critical factor in its valuation. The most prized colours are vivid red and blue, often compared to the finest rubies and sapphires. Spinel can also come in shades of pink, orange, purple, green, and even black. The intensity and purity of the colour significantly influence the gem’s desirability and price.

Colour Grades of Spinels

Spinels not only have different colour/undertone shades, but they also come in different intensities as well. At Michael Trio, our Spinel colour grades range from Vivid, Intense, Medium Intense and Light.

Clarity

Clarity refers to the presence of inclusions or internal flaws within the gemstone. Spinels are generally known for their excellent clarity, often containing fewer inclusions compared to other gemstones. High-quality spinels are those with minimal to no visible inclusions. However, some inclusions are typical and can give each gemstone a unique character.

Thumbprint Inclusion

Some inclusion within Spinel can raise its value instead of decreasing it. Spinels sometimes contain inclusions that highly resemble fingerprints. It is very unique in that it causes the value of the gem to increase.

Cut

The cut of a spinel affects its brilliance and overall appearance. Spinels are typically cut into various shapes, including oval, round, cushion, and emerald cuts. A well-cut spinel will maximise the gemstone’s natural brilliance and colour. Proper cutting enhances the stone’s ability to reflect light, making it more visually appealing.
