The cut refers to the design of the stone, such as round or oval.
Each cut sparkles in its own way and this is an important factor as it determines the shape of the stone you want to go for.
This refers to the colour of the stone.
With grey diamonds, morganites & rubies you want a colourful stone, but with white or classic diamonds you want a completely colourless stone.
Clarity refers to the number of amazing inclusions in a gemstone.
With grey diamonds we look for the most beautiful inclusions, like a scattering of stars sparkling in the night sky, but with white or classic diamonds we look for no inclusions.
Morganites are clear whilst other stones like moonstone or tourmaline have the most beautiful, exciting inclusions.
Carat is a measurement of weight, not love.
It is simply what the precious stone weighs in metric carats which are a unit of measurement like kilos or pounds.
