The 4 Cs

of coloured gemstones

The “4 Cs” — carat, cut, colour and clarity — were designed to standardise the evaluation of diamonds. When it comes to coloured gemstones (sapphires, emeralds, rubies…), the 4 Cs can serve as a guideline, but are not enough on their own to judge the quality of a sapphire, emerald or ruby. In practice, for coloured gemstones we prioritise a detailed assessment of the colour (quality and intensity), a cut suited to the crystal type and any treatments applied, in addition to weight and transparency.

Carat, the weight of the gemstone

CARAT

The weight of the gemstone

The carat measures the weight of the gemstone. It remains relevant for all gems, as it determines size and price. The larger a gemstone, the rarer and more valuable it is. However, the cut and quality also influence its beauty and value. Large stones are rarer, but a small well-cut gemstone can be just as precious.

Cut, the cut or shape of the gemstone

CUT

The cut, or shaping, of the gemstone

The cut of the gemstone is a key criterion for maximising its brilliance. A well-executed cut allows the stone to catch light and sparkle optimally. Faceting requirements vary according to the crystal structure. At Edenly, we ensure each gemstone is cut to reveal its natural radiance, focusing on “Good” and “Very Good” cuts to optimise its beauty.

Colour, the colour of the gemstone

COLOUR

The colour of the gemstone

Colour is one of the most important criteria in gemstone evaluation. For stones like ruby or sapphire, depth and intensity of colour determine rarity and value. Coloured gemstones are graded on hue scales ranging from the palest to the richest. For example, a deep blue sapphire or an intense red ruby is more valuable than a paler stone.

Clarity, the clarity of the gemstone

CLARITY

The clarity of the gemstone

Clarity refers to the natural inclusions or imperfections inside the gemstone. The fewer visible inclusions to the naked eye, the higher the quality. A++ quality gems are highly sought after as they are transparent with no major inclusions and offer exceptional clarity. Most coloured gemstones have natural inclusions; these are more tolerated than in diamonds and are judged by their visual impact rather than a strict clarity standard, adding to each gem’s authenticity.

Quality, Certification and Origin of Edenly Gemstones

At Edenly, we select only gemstones that meet very strict quality criteria. Each gemstone is chosen for its exceptional brilliance, colour and clarity.
