HAMISH WHITING GIA Gemologist and HRD Antwerp Diamond Grader
Hamish Whiting is one of the three founders of our jewellery brand and our in-house Gemologist. Hamish is a highly skilled and very experienced buyer of diamonds and precious gemstones.
Hamish has taken what he has learned during his Gemology and Diamond Grading studies at the GIA in Carlsbad, and the HRD in Antwerp, and further enhanced his buying through his years of experience and extensive research.
He has built a strong network of trusted and ethically responsible suppliers all over the world and purchases all of our gemstones directly. We are very proud to be able to offer Hamish’s skills to our customers.
His passion for what he does is evident if you ever meet him and in the gemstones that we have in our stock.
All of our modern cut diamonds are GIA certified and carefully hand-selected by our GIA Gemologist, Hamish Whiting. Hamish purchases all of our diamonds directly from the largest international diamond Global Sightholders who cut 90% of the world's diamonds. He buys our stock carefully over time with patience and expertise to ensure that we always have a collection of the most high performing and best value diamonds for our customers.
The biggest mistake people make when buying a diamond is buying based on the GIA/diamond certificate alone, also known as “buying blind”. A certificate cannot guarantee whether a diamond is beautiful or not. Even diamonds that look perfect on paper can be unflattering in reality. This is why we go well beyond the GIA certificate to make sure we are offering our customers the most high performing diamonds for the right price, what we call “smart buying”.
Cut quality is the single most important factor in determining a diamond's light performance, beauty and sparkle - however it is also the least understood by diamond purchasers and even diamond retailers.
Cut refers to the angles and proportions of the diamond, which determine how a diamond’s facets interact with light. A well cut diamond will display superior brightness, fire and scintillation compared to one that is not well cut.
A poorly cut diamond will exhibit light leakage in the form of undesirable dark zoning, such as bowties, fish eyes or transparent “windows” through the stone.
The three components of diamond cut which determine a diamonds beauty and sparkle:
The majority of natural diamonds found in the earth are slightly tinted yellow or brown. Completely colourless diamonds are much more rare and also generally much more desirable for their “icy white” appearance.
The colour scale for diamonds starts at ‘D’ for colourless stones and continues with increasing presence of colour to ‘Z’. Diamonds are exponentially more rare as they have less colour which directly affects the value.
Inclusions are natural growth characteristics which occur during the formation process of the diamond deep in the Earth’s crust. Most diamonds will have inclusions. Those that have none or almost none are very rare, and rarity directly affects value.
The GIA clarity scale is a measure of the impact of the inclusions in a diamond when viewed under a loupe at 10x magnification. It ranges from ‘F’ for a flawless stone, right down to ‘I3’ for a stone with very obvious inclusions.
Diamond fluorescence is the effect that ultraviolet (UV) light has on a diamond. When you stand under a blue light or ultraviolet light, sometimes you can see your whites get brighter or your teeth appear to glow.
This is the same effect the diamond has under the UV rays. A third of all diamonds glow blue under ultraviolet (UV) light.
Our sizing is based on the inner diameter of our ring in millimetres. Refer to the measuring chart in our guide.
