Diamond Guide

There is no other gemstone like a diamond. It is found in the most remote places on earth and the fact that it forms at all is something of a miracle. Read more below about the 4C’s of white diamonds - cut, colour, clarity, carat.

Cut

Possibly the most important of the C’s. Each diamond is expertly faceted to bring out the beauty of the gemstone. A high cut grade means a high degree of brightness, fire (rainbow colours) and scintillation (sparkle). Diamond cuts are graded in 5 levels: Excellent, very good, good, fair, poor.

Cut

Colour

A diamond’s colour is graded by the lack of colour. The highest grade is ‘D’ and extends to ‘Z’ or light yellow. Colours D-G are excellent and rare. H-I are near colourless, J-Z is slightly tinted and includes many colour shades including grey, champagne and cognac. At Meadowlark we usually use F-I, but we can help source the right diamond for your budget.

Clarity

Because diamonds are formed under tremendous heat and pressure they all contain imperfections. The very best and rare clarity is internally flawless (IF). Because many inclusions are not visible to the naked eye, diamonds are graded under 10x magnification.

Carat Weight

Diamond weight is measured in carats, one carat equals 200 milligrams in weight. All C’s combined means no two stones are the same. We recommend choosing the best quality stone over size.

Black Diamonds

Black diamonds are natural diamonds which have their colour changed with heating or irridation to be permanently black. Because they are black only the carat weight applies and the cut, colour and clarity can't be rated. Often large black diamonds have many inclusions, we aim to source the cleanest gems available

Grey Diamonds

Grey diamonds are a white diamond with many natural inclusions and shades which adds to the rustic nature of this beautiful gemstone. Because they are imperfect diamonds you tend to get a real salt and pepper effect which makes each diamond extremely unique. We cost and source the highest grade but can get cloudier options to fit within your budgets.
