Cut refers not to a diamond’s shape (e.g round, oval, pear, etc.) but to a diamond’s proportions, symmetry and polish. The beauty of a diamond depends more on cut than any other factor. The better a diamond is cut, the more it will sparkle.


Virtually all diamond cuts sold for use in jewellery are one of ten round or fancy diamond shapes. The most popular diamond shapes are:



Diamonds come in a variety of colours, some of them highly prized  (pinks, blues, even yellow). However in a white diamond, the presence of a yellow tint will lower the price of a diamond. The less body colour in a white diamond, the more true colour it will reflect, and thus the greater its value.



Because they are formed deep within the earth, under the extreme heat and pressure; virtually all diamonds contain “birthmarks” which are small imperfections inside the diamond (called inclusions), or on its surface (called blemishes). Clarity refers to the degree to which these imperfections are present.


Carat Weight

This is the term with which people are most familiar, but remember that carat is specifically a measure of the diamond’s weight.


GIA Certification for your Diamond

All of our diamonds are purchased from ethical sources and come with a GIA certificate.


It is important to have your precious pieces valued for insurance purposes. Without a valuation, you may find a surprise in the value of a piece of jewellery bequeathed to you by a relative or friend. This is also a service Claudia Jewellers offers.
