At MONTASH Jewellery Design we pride ourselves on providing diamond education on our beautiful & quality diamonds…
At MONTASH, we provide diamond education to ensure you have a full understanding of your purchase. Our Gemmologist can advise you on the best diamonds with her extensive knowledge in the 5Cs of diamond quality.
The Five Cs include:
Diamond Cut is the most important of the Cs as the cut has all to do with the reflective qualities of the diamond. A good cut is what gives a diamond its radiance. Different cuts include Ideal Cut, Fine Cut, Deep Cut, and the Shallow Cut. When a Diamond is well-cut light travels to the base where it then projects from one side to the other and mirrors back to the surface, giving the diamond its glint and luminosity.
Diamond clarity refers to the presence of inclusions within the diamond including blemishes, scratches, trapped air bubbles, or trapped non-diamond mineral material from the harsh stress that the crystal undergoes during production. Clear Diamonds are incredibly rare and are much more expensive due to the absence of inclusions.
Diamond colour indicates the ‘whiteness’ of the diamond and refers to the presence of yellow or brown tints existing in a white diamond. Colour is determined by comparing the diamond to an internationally approved set of master tones. ‘D’ is the grade for a white colourless diamond, and travels down the alphabet to grade stones with traces of very faint yellow or brown tinges.

A carat is the unit of weight by which a diamond is measured rather than its size and width. One carat is equal to one fifth of a gram. The larger the diamond the more expensive and more rare the carat will be. Size is one of the most obvious factors in determining the value of a diamond however, two diamonds identical in size can have different values depending on their quality. The carat size you desire will depend on the balance between size and quantity.
