Quality carat, colour, clarity and cut diamond rings

Diamonds come in all shapes, sizes and quality. We work with you to ensure you get the best diamond ring in Sydney, to your budget and based on the following:


A diamond’s weight is measured in carats, which ranges from 0.25 carats (4mm) up. The value of a diamond isn’t placed on carats alone, but in conjunction with the following factors:

The less the colour a diamond ring has, the higher it’s valued. This is simply because diamonds are normally characterised as having a lack of colour. Diamonds are graded from D (which are colourless and most valuable) to Z (the most saturated in colour). Fancy coloured diamonds such as pink and blue are excluded from colour grading.

Diamond Colours


Diamonds come with their unique fingerprint, due to naturally occurring grades or blemishes. What can be seen as a flaw to one person, could be the characteristic that compliments the uniqueness of the piece for another.

Diamond Clarity


Ultimately, how a diamond is cut determines how the light illuminates, how it sits on its wearer, it’s symmetry and brilliance. Per Lei’s expertise ensures you get the best-cut diamond rings in Sydney.
