About Spinel - History and Introduction
Spinel is a hard vitreous magnesium aluminum oxide that has been used as a gemstone for centuries. The beauty of spinel has caused it to be mistaken for ruby and sapphire in the past. However, spinel deserves to be recognized as a gemstone that is worthy of appreciation in its own right. Spinel occurs in a range of colors, such as rose pink to rich red; lavender to deep violet; light to deep blue, orange, yellow, brown and black.
The name spinel is thought to have come from either the Latin word, "spina", meaning thorn, due to its pointed crystal form, or the Greek word for "spark", in reference to its bright color. Spinel has been mined for centuries and one of the most famous historical spinel gemstones is known as "the Black Prince's Ruby". As the name suggests, this is a red gemstone, which was thought to be a ruby. The "Black Prince's Ruby" was acquired by Edward, Prince of Wales in 1367. It is set into England's state crown and is held at the Tower of London.

Those planning to use spinel gemstones in jewelry should first consider their preferred color. The choice of spinel colors is great, with yellow, orange, blue, red, purple, brown, black and pink possibilities. Spinel gemstones look equally impressive when set in white or yellow precious metals.

More simple but dramatic jewelry can be designed with black spinel and white gemstones such as sapphires. Tribal-style jewelry can be made with drilled spinel gemstones or wire-wrapped spinel gemstones.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Spinel Gemstone Jewelry Care and Cleaning Back to Top
Spinel's hardness (8 on the Mohs scale) makes it durable and means that it does not scratch easily. To clean your spinel, simply use soapy water and a soft cloth. Be sure to rinse well to remove soapy residue. As with most gemstones, ultrasonic cleaners and steamers are not recommended. Always remove any jewelry or gemstones before exercising, cleaning or engaging in harsh physical activities such as sports. Store spinel away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.
