Certificate & Stone Selection
Every stone
has an identity
Every diamond offered at Shusha is graded and certified by independent laboratories. Because trust must be measurable.
Trust is measurable
The certificate of the light you buy
A diamond’s worth is defined by its cut, colour, clarity and carat. Shusha documents these four measures with a report from independent gemological laboratories — so you choose with complete peace of mind.
The language of the diamond
The diamond’s four measures — 4C
Worldwide, every diamond is assessed by the same four measures: Cut, Color, Clarity, Carat.
Cut is the most critical measure of a diamond’s brilliance; it shows how well the stone captures and returns light. A poorly cut stone can look dull despite high colour and clarity. Shusha offers only Excellent and Very Good cut stones.
In a diamond, “colour” actually means colourlessness. The scale starts at D (completely colourless) and warms toward Z with faint yellow tones. The less colour, the clearer and more valuable the stone. Shusha collections are selected in the D–H range — stones that read white to the eye.
Clarity reflects how few natural inclusions sit inside and on the surface of the stone — the fingerprint of its formation in nature. VVS and VS grade stones, flawless to the naked eye, form Shusha’s core standard.
Carat expresses a diamond’s weight — not its size. One carat equals 0.20 grams. Two stones of the same carat can look different in size depending on their cut, so carat should be read together with cut, never alone. Shusha offers certified options from 0.10 to 3.00 carat.

The right stone for you
Choosing by your priority
The perfect stone is the one that balances your budget with your priority. A few pointers.
Keep cut at the top. An Excellent cut comes before colour or clarity; it is what truly brings the light to life.
Focus on colour. The D–F range gives an icy-white look, especially pronounced in white gold and platinum.
Choose the eye-invisible threshold: G–H colour and VS clarity look almost identical to the top grades and hold their value.
A stone with good cut proportions and slightly lower colour will look larger and bright for the same budget.
