A diamond is given a grade to describe the level of inclusions or imperfections. The less imperfections, the better the clarity. All diamonds have inclusions. It’s what makes them unique like a fingerprint. And as we promise only the best for our customers, all our platinum and 18 carat gold diamond rings are graded by the best graders and valuers in the world. Roxanne Rajcoomar-Hadden,  diamond specialist, will help you through the process every step of the way. 


The colour grade describes the colour tones in a stone. The diamond colour grade starts at colour D, which is perfectly colourless. The colour scale goes from D to Z and indicates yellow and brown tones. It takes a trained eye to distinguish between shades that are close together, but an untrained eye see the difference between shades that are several tones apart with a little practice. Pink, blue, red, and green diamonds are also found, but they are very rare. These fancy coloured diamonds don’t follow the normal colour/price scale and are priced separately.


A carat is often confused as the size of a diamond, when in fact it is actually the measure of a diamond’s weight. Put simply, the more a diamond weighs, the rarer the diamond is.    The word carat is derived from carob. In ancient India gems were weighed with carob beans that all weighed exactly the same.


Cut refers to the reflective qualities of the diamond. Behind every quality diamond is a skilled cutter. We take great pride in scrutinising the cut of each diamond we hand select, as only those most precisely cut perform with true fire, brilliance and scintillation. Very Good Cut - A diamond with a very good cut has very strict requirements for depth and table percentages. These proportions give the stone a maximal brilliance and icy fire. Good cut - A diamond with a good cut has acceptable but imperfect proportions. Its brilliance and fire is good, which makes it a good stone for jewellery. Fair cut - A diamond with a fair cut has less than perfect proportions to make the most of the weight. This cut sacrifices the brilliance of the stone. Poor cut - A poorly cut diamond has imperfect proportions that make it look lustreless. Diamonds with a poor cut are not recommended for fine jewellery.

PLATINUM is very durable,  hard-wearing, hypo-allergenic. It is  the hardest of all the alloys. Platinum, which is naturally white, will not fade to yellow, like white gold can.

18CT YELLOW GOLD is 75% gold, mixed with other alloys. It is durable and does not tarnish, corrode or react with its owners skin. This is an ideal metal alloy for making pieces such as engagement and wedding rings that need to last at least a lifetime!

WHITE GOLD is composed of gold, alloys, and a rhodium plating which gives it a white look that’s very similar to platinum. While white gold looks very similar to platinum, over time the the rhodium plating in white gold will wear off and fade to a yellowish tinge. Once you re-polish and re-plate the white gold ring, it will look white again.

FAIR TRADE gold and precious metals’ is a ground breaking initiative that offers a lifeline to poor and exploited small-scale miners around the world. It links consumers of jewellery with the source of their purchase. It is this link through Fairtrade standards and certification that makes Fairtrade gold the best gold in the world. RRH Jewellery uses Fairtrade gold for all collections and bespoke work. For further information please get in contact.
