RUUSK’s Guide to Diamonds

Buying a Diamond ring can be all sorts of confusing; from cut to colour to carats, we're here to help you understand how each element comes together to make this precious stone even more stunning. When selecting a Diamond for you to treasure for a lifetime there are 4 main Cs you need to consider: CUT, COLOUR, CLARITY & CARAT.


The cut of the Diamond determines its brilliance. Essentially, the better a Diamond is cut, the more sparkle it will have. All RUUSK Diamonds are sourced by trained Diamond specialists to ensure the best quality cuts.

The cut of a Diamond can also refer to the shape of the stone. The most popular cut is the round brilliant cut, but variations include oval, pear, cushion, princess or emerald, depending on personal preference.


In the world of Diamonds, the less colour the better. The closer a Diamond is to being ‘colourless’, the rarer it is. Grading of colours is based on a scale from D-Z, with D being colourless and the rarest, and Z having a yellowish tint.

All classic RUUSK Diamonds range from F-G in colour, putting them in the ‘colourless’ to ‘near colourless’ or ‘rare white’ category. Diamonds of higher quality, ranging up to D, can be sourced upon request.


Diamond clarity refers to the purity of the stone. Almost all Diamonds have tiny imperfections which are graded according to the visibility of these characteristics under high magnification or the naked eye. Grading ranges from flawless (no visible or internal imperfections) to slight imperfections, to imperfect.

RUUSK works with Diamonds graded VS in clarity or higher. VS Diamonds are eye-clean with only minor inclusions that can sometimes even be hard to see under 10x magnification.


The carat is an ancient unit used to describe the weight of gemstones. One carat is equal to 0.20 grams. Larger Diamonds are rarer than those of smaller carat weight and size. However, taken by itself, carat weight does not determine the value of a Diamond. Cut, Clarity, Colour and Carat must all be considered upon determining the quality of your Diamond. 

All RUUSK Diamonds over 0.5 carat come with a GIA certification – an internationally recognised Diamond grading report which outlines your Diamond’s carat weight, measurements, colour, clarity and cut.
