GIA Accredited Diamond Jeweller

Launched in 1931 with the sole aim of maintaining the quality and sourcing of diamonds across the planet, the GIA is the world's leading authority on this most precious stones. As a GIA Accredited diamond supplier, we source only the finest, responsibly collected diamonds on behalf of our customers to ensure that your piece of diamond jewellery is as beautiful as it can possibly be. This includes looking at what jewellers call 'The 4 C's' which are made up of the following:

1. Cut: Cut quality is the factor that fuels a diamond’s fire, sparkle and brilliance. The allure and beauty of a particular diamond depends more on cut quality than anything else. The GIA's Diamond Cut Grading system is based on seven criteria. These are Brightness, Fire, Scintillation (the pattern of light and dark areas and the flashes of light, or sparkle, when a diamond is moved), Weight Ratio, Durability, Polish, and Symmetry.

2. Clarity: Because diamonds are formed deep within the earth, under extreme heat and pressure, they often contain unique birthmarks, either internal (inclusions) or external (blemishes). Diamond clarity refers to the absence of these inclusions and blemishes. Diamonds without these birthmarks are rare, and rarity affects a diamond’s value. Using the GIA International Diamond Grading System™, diamonds are assigned a clarity grade that ranges from flawless (FL) to diamonds with obvious inclusions (I3).

3. Colour: Diamond color is all about what you can’t see. Diamonds are valued by how closely they approach colorlessness – the less color, the higher their value. (The exception to this is fancy color diamonds, such as pinks and blues, which lie outside this color range.) Most diamonds run from colorless to near-colorless, with slight hints of yellow or brown. The scale begins with the letter D, representing colorless, and continues with increasing presence of color to the letter Z, or light yellow or brown

5. Carat: Diamonds and other gemstones are weighed in metric carats: one carat is equal to 0.2 grams, about the same weight as a paperclip (don’t confuse carat with karat, as in “18K gold,” which refers to gold purity). Just as a pound is divided into 100 pennies, a carat is divided into 100 points. For example, a 50-point diamond weighs 0.50 carats. But two diamonds of equal weight can have very different values depending on the other members of the Four C’s: clarity, color and cut.
