What is a parti sapphire?
A parti sapphire is a sapphire that displays two or more colours, typically blues, greens, and yellows. The colours of parti sapphires are separated as if cleanly partitioned, hence 'parti' in the name.

A similar colouring is the equally beautiful teal sapphire. Not to be confused with the parti sapphire, this colour also features blues, greens, and yellows, but as a single blended colour.

How are parti sapphires formed?
Naturally occurring parti sapphires get their unique colour partitioning from the environment. Like all other sapphires, parti sapphires are a variety of the mineral corundum, a crystalline aluminium oxide which forms deep below the earth's surface.
As the crystals form and grow, they are exposed to various trace elements which affect their colour, such as iron, chromium, magnesium, and titanium. In the environments where parti sapphires are found, there are unusual combinations of these elements, interacting with different parts of the crystals and resulting in specific zones of colour.
Ethical sourcing
We source our stunning parti sapphires from Australia, home to an incredible array of stone colours and ethical sapphire sourcing operations. Australia's gemstone mining industry is highly regulated, with strict rules enforced by state governments supported by the country's labour laws. Once the sapphire mining operations have ended, the land must be restored to its original condition.
At Wild Fawn, we pride ourselves on only using sustainable materials, ethically sourced gemstones, and lab-grown diamonds. The planet and its people are important to us, which is why we're dedicated to our environmental commitments. Our jewellery pieces, including our parti sapphire engagement rings, are made in our eco-friendly studio in London, where we use chemical-free alternatives wherever possible.
Are parti sapphires good for engagement rings?
Yes, parti sapphires are a wonderful choice of gemstone for a unique engagement ring. Their spellbinding colourways make them truly unique, turning an already beautiful ring into something beyond special. As well as their captivating design, natural sapphires are hard and durable, ideal for those worried about scratches or with active jobs or lifestyles. Our range of made-to-order parti sapphire engagement rings has something to suit all jewellery tastes, from singular sapphires to gemstone clusters.

How to care for a parti sapphire ring
Parti sapphires are extremely hard, ranking 9 on the Mohs Hardness Scale, just one place behind diamonds, the hardest natural substance on earth. These striking gemstones are hard enough to withstand scratches from everyday objects like keys and coins, making them better than other gemstones for engagement rings, which may suffer daily bumps and scuffs.
Thanks to this hardness, they're a very durable stone, but unfortunately not quite indestructible. Avoid wearing a parti sapphire engagement ring while working with harder materials, and remove it when using abrasive cleaning products. Although chemicals such as bleach and chlorine won't damage an untreated sapphire, they will certainly damage the metal settings it's held in, which could result in a lost stone.
