The most important things to note in a Diamond are Cut, Clarity, Colour, Carat Weight and Certificate.  These are known as the 4 c's are universally used to grade Diamonds. 

Diamond Cut
The brilliance of a diamond depends heavily on its cut as it is the diamond's reflective qualities.  The grading of the cut are Ideal, Premium, Very Good, Good and Fair & Poor, we don't sell good or fair & poor diamonds as we believe that a diamond ring without  sparkle is a diamond with little beauty, your engagement ring is forever and buying from us allows you the biggest and the best for your budget.

Ideal Cut is intended to maximize brilliance and applies only to round Diamonds.

1. Premium cut is intended to provide maximum brilliance and fire.
2. Very Good cut reflect most of the light that enters them to create their brilliance. 
3. Good cut  reflect much of the light that enters them.
4. Fair & Poor cut reflects only a small proportion of the light that enters it and often for maximizing carat weight.

Diamond Clarity
All Diamonds contain inner flaws (inclusions) that naturally occur.  The visibility, number and size contribute to the clarity.  Therefore the fewer the greater the Clarity.  Flaws are known as inclusions which are air bubbles, cracks, other minerals, scratches, pits, and chips in the Diamond.  Grade list: 

1. F = Flawless,
2. IF = Internally Flawless,
3. VVS1 and VVS2 = Very Very Slightly Included very difficult to see with 10x magnification,
4. VS1and VS2 = Very Slightly Included seen only with 10x magnification,
5. SI1 SI2and SI3 = Slightly Included easily seen with 10x magnification,
6. I1and I2 and I3 = Included and visible to the naked eye.

Diamond Colour
Colourless diamonds are the most expensive and sought after, as they tend to sparkle more.  The more the colour the less sparkle and therefore less desirable.  Whiteness is graded with a colour scale that begins at D for colourless and ends with Z for a brownish-yellow

• Colourless = DEF,
• Near Colourless = GHIJ,
• Faint Yellow = KLM,
• Very Light Yellow = NOPQR,
• Light Yellow = STUVWX and on…

Diamond Carat Weight
This is a unit of weight of a diamond.  Prices rise greatly with its size. See our diamond size guide for mm per carat sizing.

Diamond Certificate
The certificate or grading report is a professional evaluation of a diamond and as such is just as valuable as the Diamond itself to a buyer or seller, and even the owner as it describes the Diamond in such great detail that it’s fingerprint.

Certificates also serve as proof of the diamond's identity and value, but a certificate is not a valuation, it only documents the quality but all our diamond engagement rings come with a full appraisal that out lines the recommended retail price which is needed for insurance purposes.
