A newer addition to the family of corundum gemstones black sapphires are the darkest variant and hold a niche position. Not much is known about black sapphires, as they are not widely adopted in the world of gemstones and also in the market for fine jewellery. Black sapphires are natural corundum stones that have the exact chemistry of other more popular variants like blue sapphires. Meaning they feature aluminium and oxygen atoms ((Al2O3). However, they differ in certain important ways.

Black sapphires are an interesting addition in that they are found in larger quantities, depending on what country you are looking at, with nations like Australia being a major source of these stones. Thus from a supply standpoint, the black sapphire's selling point is not their rarity. However, when it comes to gemstone quality stones, acquiring black versions of these stones may prove to be challenging. Since black sapphire stones are known for their higher impurity levels, getting your hands on a black stone with fewer inclusions may prove to be challenging. On the positive side, the dark hue of this particular sapphire stone help disguise such blemishes.

Potential buyers are likely to be curious about how black sapphire gets their colour? Sapphires are hardened minerals that get their colour from the presence of trace elements. With iron, titanium, magnesium and to a lesser extent chromium and vanadium dominating. The visibility of colour depends on the type of colours in the light spectrum, and by extension the level of light, the gemstone is able to absorb; with trace mineral character being the key determinant.

In black sapphires, a considerable level of light is absorbed, rather than being reflected outward, hence its distinct colour. In black sapphire, the higher presence of iron and titanium, which at moderate levels give rise to the conventional blue sapphires, gives them their darker hue. In some cases, black sapphires can be confused with deep blue sapphires, as some variants are extremely dark. But black sapphire features a distinct hue that sets them apart from the rest. However, given the chemistry of the stone, black sapphires technically can be considered to be at the extreme end of the blue sapphire range. With Brilliyond you stand to get the best in class gems, all naturally sourced and cut to specification. Which can be purchased individually or as a part of fine jewellery items, like black sapphire engagement rings

The next main question on the mind of a potential buyer is why bother? Why choose the black sapphire stone. It might be curious to note that black precious stones have established a following across the world. Since colour is a key component when selecting a gemstone, gems which feature distinct black hues have a special market. The industry currently is dominated by gem-quality versions of black onyx stones: which is a variant in the agate family of crystals. Black sapphires in this context are superior alternatives, with higher durability (9 vs 7 - 6.5 on the Mohs scale), better reflective capability and uniform colours, as opposed to the banded character of the onyx stones. In addition, black sapphires build on the historical reputation of sapphires as gem-quality stones, which are tailored for fine jewellery, to be cut and sold as individual gemstones. In recent times, new black sapphire sources have been unearthed in other parts of the gemstone mining world, with traditional centres like Thailand, Ceylon and even Cambodia entering the mix.
