What cut of diamond does Comete use?

Comete favours the brilliant cut in its JEWELLERY, the cut that most enhances the brilliance and shine of all precious stones.

What purity do Comete Diamonds have?

Our JEWELLERY uses mainly SI Purity and G Colour diamonds. Diamonds often have some tiny imperfections inside them, called inclusions. The clarity scale ranges from F (Flawless = free of imperfections) to I (Included = inclusions). Therefore, SI Clarity for a diamond determines how many tiny imperfections the diamond has, based on the clarity scale. In this specific case, SI is the abbreviation for Small Inclusions and applies to diamonds whose inclusions are small, but visible with a 10x magnifying glass.

Are Comete Diamonds Certified?

In collaboration with the IGI, Italian Gemmological Institute, we offer our consumer a certification of authenticity  and value of the Comete diamond for JEWELLERY with diamonds from 10 Carat Points upwards.

How much is 1 Carat?

What is the Diamond?

Diamonds originate in the Earth's mantle, where the very high pressure conditions necessary for their formation exist. The crystals are brought to the surface, encased in a rock containing a lot of olivine called kimberlite, by volcanic conduits through eruption. This gives rise to the diamond chimneys of the primary deposits. Later, through erosion, the kimberlite can be crushed, releasing the diamonds into secondary deposits, usually alluvial.
