Diamond guide

Like any investment, your first diamond purchase requires some contemplation. The colour, shape, size, weight and clarity are just some of the considerations that will greatly influence your decision.

Like you, diamonds are unique with no two exactly alike. At Nina’s Jewellery we will guide and assist you through the myriad of choices to ensure you find your perfect diamond.

Cut

The best-cut diamonds are those that reflect the greatest amount of light allowing the stone to sparkle and radiate its natural beauty. This can only happen with the hands of a highly skilled craftsman.

Example showing diamond cuts: Princess, Oval, Radiant, Pear, Emerald, Heart, Brilliant, Marquise

Carat

A diamond’s weight, and therefore size, is expressed in carats. In ancient times merchants used the carob seed as a base unit of weight when assessing diamonds. This unit of measurement has become what is commonly known as a carat, and has a weight of 200 milligrams. The below scale is indicative only.

Clarity

Each diamond has tiny birthmarks called inclusions, which like fingerprints, makes each stone unique. A diamond of exceptional clarity has minimal inclusions to interfere with the passage of light through the stone.

There are actually five C’s

Diamonds are valued using a universal process known as the four C’s - Colour, Clarity, Cut and Carat. This classification process, once complete, determines the fifth C - Cost. Discovering which of the four C’s is most important to you will help keep your investment affordable.

Colour

It wasn’t that long ago that people thought that the best diamonds were white. Argyle’s discovery of brilliant pink, champagne and cognac diamonds changed that perception forever - in fact, the richer the colour, the higher the price the diamond will fetch.
