Grey and Salt & Pepper Diamonds
Where they're formed
Unfortunately there are currently no standards in place to track the exact origin of most salt & pepper and grey diamonds, however the stones we use are all sourced through the Kimberly Process-approved vendors, which is the industry standard for ethical, conflict-free origin.
Unlike traditional white and coloured diamonds, salt & pepper and grey diamonds do not currently have a grading system to determine qualities such as cut, colour or clarity. We only use stones that are appropriate for use in jewellery that is intended to be worn for a lifetime. We specifically source stones without coloured inclusions (such as red, brown or orange material), without any colour undertones to ensure the brightest, clearest 'white' or grey colour, and for material that has beautifully unique patterns. As these diamonds do not follow traditional grading systems, there is no 'right' or 'wrong' stone in terms of its inclusions and patterning, it is up to the client to choose the stone that appeals to them aesthetically.
Black carbon inclusions and internal feather-like fractures that are commonly dispersed throughout these stones are not unstable and shouldn’t affect the diamond's durability in any way. Salt & pepper and grey diamonds have the same durability and hardness as a white diamond, but as with a white diamond should still be treated with care to avoid breaking or chipping the stone.
Salt & Pepper diamonds range from clear through to cloudy white or grey, and can have varying intensity of black inclusions. They can also have undertones of brown, champagne or yellow. Grey diamonds range from icy white through pale grey to opaque dark grey.
Salt & pepper and grey diamonds do not come with certification as industry standard. Independent certification can be arranged by request.
Until recent years, these diamonds were not accepted within the industry which valued traditional white diamonds as the epitome of jewellery-quality stones. They were most commonly used for industrial purposes as they did not fulfill the aesthetic qualities expected of a diamond. Today they are coveted as a unique alternative to a traditional diamond, and are extremely affordable in comparison.
