Start With A Diamond

Clarity: The visual appearance of a diamond is assessed through internal characteristics known as inclusions and blemishes. The GIA has an 11-point grading system ranging from ‘Flawless’ at the top of the scale, to ‘Included’ for those with imperfections.

Cut: The way that a diamond is cut is crucial to how it interacts with the light. A stone’s facets are analysed to evaluate how successfully a diamond transmits three qualities: brightness, fire and scintillation.

Colour: The higher the absence of colour in a white diamond, the greater the value of the diamond. Colour distinctions can be so subtle that they are often invisible to the untrained eye.

Carat: A carat refers to a unit of weight; 200 milligrams equals 1 carat. As larger diamonds are rarer and so more desirable, the higher the carat of a diamond, the greater its value.

Steven Stone is proud to only offer diamonds certified by the Gemological Institute of America (GIA), an independent, non-profit organisation that is the global authority on diamond grading and gem identification. Each stone comes with a report card detailing the specific analysis carried out on a diamond of any shape or size above 1 carat and features a comprehensive assessment of a stone’s 4Cs. Such grading measures enables the customer to competently compare stones like for like.

These are diamonds sourced responsibly and ethically and which do not support any illegal activities, such as financing war or terror groups. Conflict free stones can be traced back to their origin.

Also referred to as lab grown diamonds, synthetic diamonds and man-made diamonds, these are stones produced not through mining, but in laboratories under controlled conditions. Considered to be a more environmentally responsible choice, a lab created diamond has the exact same physical and atomical qualities as a mined diamond.

At Steven Stone we believe that the cut of the diamond is the most important. When a diamond is cut well it increases the sparkle and the overall look and impact of the stone.
