All RUUSK Diamonds are conflict-free and purchased from accredited Diamond suppliers. We take care to source beautiful high quality Diamonds for all RUUSK collection pieces and each is sourced in accordance with the Kimberley Process* 

All Natural Clear Diamonds used in collection pieces are G-F or above in colour, placing them in the Rare White colour scale and each has VS, or above, clarity. All of our RUUSK diamonds have been cut by a trained Diamond lapidarist or stonecutter. 
RUUSK pieces with a 0.5ct, and above, Natural Clear Diamond come with certification from the Gemological Institute of America (GIA) identifying your Diamond's carat weight, measurements, cut, colour and clarity. GIA certificates are an internationally recognised Diamond grading report. 

And so you can understand the Diamond Grading parameters RUUSK works within, we've put together a guide on how we select the Clear Diamond for your very special piece so you can treasure your Diamond for a lifetime. 



When referring to cut, this can mean different things. Most understand the cut of a Diamond in relation to the shape of the stone and there are a range of shapes you can request a Diamond to be cut into. We predominantly work with a Round Brilliant Cut but also offer pieces with Pear, Oval and Princess Cut Diamonds.

Otherwise, Cut can also refer to the quality of the workmanship or craftsmanship that went into aligning and polishing the diamond’s facets. This can be seen on a GIA certificate where they assess the Diamond's brilliance and sparkle. All RUUSK Diamonds are sourced by trained Diamond specialists to ensure the best quality cuts.


Diamonds are graded on a colour scale with the scale beginning with the letter D (we like to remember this by thinking of D for Diamonds) and ending with Z; D representing colourless Diamonds and Z, a light yellow or brown Diamond. 

All Diamonds used in RUUSK Collection pieces are F-G in colour, or above, putting them in the colourless to near colourless or rare white category. We can specifically source Diamonds with D or E colour on request so please let us know if this would be of interest. 


Many of these colour distinctions are so subtle as to be invisible to the untrained eye. But these slight differences make a very big difference in diamond quality and price. Generally the more colourless, the higher their value. 


Because Natural Diamonds are formed in the Earth, they often contain "unique birthmarks" either internal (known as inclusions) or external (known as blemishes). Diamond Clarity refers to the absence of inclusions and blemishes, grading the purity of the stone according to the visibility of these characteristics under high magnification or to the naked eye. 
Almost all Diamonds have these tiny imperfections and Diamonds without these birthmarks are extremely extremely rare & expensive. Known as Flawless diamonds, most jewellers will never see one in their lifetime!

RUUSK specifically sources Clear Diamonds graded VS in clarity or higher (VS stands for Very Slightly Included). Which means all our diamonds are eye-clean with only minor inclusions that can sometimes even be hard to see under 10x Magnification. We can specifically source Diamonds with VVS (Very, Very Slightly Included) clarity grading on request. 


Carat is an ancient unit used to describe the weight of gemstones; one carat is equal to 0.20 grams. And larger diamonds (those with higher ct's) are rarer than Diamonds of a smaller ct weight. 
However, taken by itself, carat weight does not determine the value of a Diamond. So we always consider Cut, Clarity, Colour and Carat in conjunction when sourcing your very special Diamond for you. That way, we can gain a bigger picture as to the overall quality of your Diamond. 


Although Diamonds are the hardest of all gemstones, (diamonds are the hardest substance known to man - the only thing that can scratch a diamond is another diamond!) they are not indestructible so please take care when wearing your jewellery. To look its best, Diamond jewellery has to be cleaned regularly and the safest method for cleaning Diamond jewellery is a soft toothbrush and warm soapy water followed by a good rinse in hot water.

Every other year, you should have your piece checked by a professional jeweller for wear or damage to ensure that your stone remains safely set.
*(The Kimberley Process was established in 2003 by the United Nations to prevent “conflict diamonds” from entering the mainstream rough diamond market. This means every Diamond purchased isn't from suspect sources, unknown suppliers or suppliers in countries that have not implemented the Kimberley Process Certification Scheme)
