Where can I learn more about diamonds?

You wish to have a larger knowledge about diamonds before buying one or simply by pure curiosity? Golsong offers two hour classes in London and in Brussels, during which she will talk about the 4C’s, the mining, the fake and lab grown diamonds as well as teach you how to look at them. Visit the “Classes” page in order to know more about these sparkling two hours. 

What are the 4C’s?

The 4C’s is the industry standards for assessing a diamond’s quality.

• Cut
• Colour
• Clarity 
• Carat weight

Golsong’s gemmologist carefully consider all these factors and plenty more to ensure your full satisfaction when searching for your diamonds. 

Cut

Diamond cutting requires great knowledge and accuracy; we source our diamonds from a close network of suppliers who excel at both. Even our melee diamonds – the small sided stones of usually less than 0.05ct – are selected based on the 4C’s.

The cut of a stone also refers to its shape. The round brilliant cut is currently the one used the most on the market. Its multi-facets (57) and symmetrical design give them an exceptional sparkle which works especially well on engagement rings. 

However, beside the round brilliant there is a huge variety of cuts which you can ask for. At Golsong we are always ready to hunt for exciting new ones. Contact us here

Colour

Using colour to describe a diamond is something not always easy to see and understand for an untrained eye. Golsong’s gemmologist are always there to help you choose and analyse your diamond colour, whether white or colourful each stone has its own beauty!

Graded on a scale from D to Z, the finest-quality white diamonds are at the top of this one. It is this absence of colour that intensifies the flashes of fire visible in the very best diamonds. D and E colour diamonds are frequently referred to as "exceptional whites" reaching high prices, F and G as "rare whites", difficult to distinguish but commonly used on the market, only an experienced gemmologist, such as Ghislaine, director of Golsong and GIA gemmologist, can make the difference between them. 

The rarest diamonds are the fancy colours such as red, blue, pink, green, orange, purple up to black. Prices tend to relate their beauty and rarity. However, Golsong does work with fancy coloured diamond suppliers and is happily helping you find the stone of your dream, whatever its size. 

Clarity

Each diamond is unique, like a snowflake. Nearly all contain crystals or minerals, formed during their creation in the earth and visible to the trained eye as minuscule inclusions. It is these tiny blemishes, known as inclusions, which affect a diamond's clarity and make it possible to compare two diamonds of exactly the same cut, carat and colour.
