Mele have a range from 0.001 - one thousandth of a carat - to 0.29 carats, and are usually in diameter from 0.6 mm to 4.2 mm. In Indian trade, mele diamonds ranging in size from 0.001 carats to 0.025 carats are called "asterisks."


LabGrown diamonds are grown in strictly controlled laboratory conditions using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle of the earth's crust


Moissanite is a rare mineral of the class of natural carbides of the composition SiC (silicon carbide). It forms small, colorless crystals with a diamond sheen.

Synthetic corundum is grown by the Czochralski method.
