Diamonds are classified according to the 4 C’s — colour, clarity, cut and carat weight — a globally accepted standard for understanding the personality of a stone. This is, however, only necessary when choosing a traditional white diamond. Champagne, cognac, and colour diamonds do not follow the same process, and are celebrated and chosen for their unique hues and patterns.
When it comes to selecting your white diamond, one should always pay close attention to the 4 C’s. It’s important to consider these specifications, as they play an overall role in your stone’s brilliance, sparkle and overall quality. Based on your individual needs and budget, we will source a diamond that suits you best.
Traditionally, a diamond’s value is determined by the absence of colour. The “whiter” the diamond, the higher the value and rarity. Colour grading starts at D (the “whitest”) and moves up the alphabet, increasing in yellow hues as it escalates.
Clarity refers to the internal or external inclusions (small imperfections) that are visible in or on the surface of a diamond. They prove that the diamond was formed naturally over time under great pressure, and are important to note as they will determine the path of light. The less internal inclusions and fractures in the diamond, the better the refraction of light.
The cut refers to the proportions, symmetry and polish of a diamond. These factors are extremely important in the refraction and the reflection of a stone.
4. CARAT WEIGHT
Carat weight is the actual weight of the diamond and this factor will have the most noticeable influence on the price of your stone.
These diamonds have a beautiful, antique aesthetic and have similar qualities to white diamonds - boasting their own unique vibrance and brilliance. Champagne and cognac diamonds come in different tones ranging from C1, the lightest to C7, the darkest.
While colour diamonds share the same hardness and durability as white diamonds and are formed in exactly the same way, they are incredibly unique in appearance. Their high concentration of internal inclusions means that the 4C’s do not apply to colour diamonds and that it is, in fact, the very thing that gives them their captivating patterns and colour. The array of hues and tones available is vast, and include salt and pepper, opaque, colour and icy diamonds .
THE ROSE CUT
A popular choice for colour diamonds, rose cuts have a flat base and large pavilion with bigger triangular facets. As colour diamonds do not refract light, the bottom table facet is not necessary. Dating back to the 16th century, rose-cut diamonds and gemstones have an old world charm that is truly unique. Rose-cut stones do not refract light the same as white brilliant-cut diamonds, but their larger, triangular facets will display bigger and bolder flashes of light and colour.
