GIA 4Cs

Diamonds have long been the ultimate emblem of enduring love—celebrated for their rarity, resilience, and timeless brilliance. Formed deep within the earth over billions of years, each diamond carries a legacy of strength and permanence, making it not only a symbol of commitment, but a piece designed to be cherished and worn every day.

Selecting the perfect diamond is a refined and meaningful experience. At the heart of this process are the four essential qualitie, known as the 4Cs which together define a diamond’s character and value. Understanding these elements allows you to navigate your selection with confidence and clarity, ensuring a choice that is as personal as it is exquisite.

A diamond’s true beauty is revealed in the way it interacts with light. It captures, reflects and refracts illumination to produce an elegant play of brilliance, fire, and scintillation. Each facet contributing to its unique visual signature. When the 4Cs are perfectly balanced they create a harmonious composition, allowing the diamond to radiate with exceptional life, depth, and sophistication.

All natural & lab grown diamonds over the carat weight of 0.50ct come with a GIA Certificate.

Colour

Color comparison chart of gemstones labeled D, H, N, and Z showing decreasing color intensity from left to right.

the scale starts at D however these are very rar and most diamonds available are nearly colourless or with tints of yellow or brown. Coloured diamonds come in a myriad of colours. The colour is created interstitial impurities or structural defects. These diamonds are can be slightly more reasonable in cost. An exception to this are Pink or blue and red diamonds are the rarest and most expensive.

Four diagrams labeled 'GIA Clarity Diagram Examples' illustrating different clarity grades of diamonds with geometric patterns and markings.

Clarity

Diamonds are created deep under the Earth with tremendous heat and pressure. The heat and pressure create imperfections such as marks and black dots called birthmarks, inclusions or characteristic; here less is more!

Cut

Chart displaying various cuts of diamonds with labels such as Single, Brilliant, Portuguese, Trilliant, Heart, Radiant, Peruzzi, Princess, French, Cushion, Lozenge, Oval, Emerald, Pearl, Marquise.

The brilliances of a diamond is created by cut and how light reflects and refracts around the shape. The more precise the cut the more alive the stone becomes with rainbows and sparkle.

Carat

A chart displaying various sizes of round brilliant cut diamonds, with measurements in millimeters and carats, arranged from smallest to largest.

A diamond’s weight is measured by the metric “carat” it is defined as 200 milligrams. Each carat is subdivided into 100 points therefore 0.5ct is half a carat.
