Clarity, Colour, Carat Weight and Cut.

WHAT IS DIAMOND CLARITY?

The clarity grade is based on any tiny natural identifiers found within a diamond.

Michael Arthur is very specific about the diamonds he sets in his pieces and makes sure they are free from inclusions that are visible without magnification. We recommend these diamonds for the best performance and value for money.

The shape of a diamond can affect the importance of its clarity grade. While the facets of round and princess cut diamonds can hide certain imperfections, step cut shapes such as emerald and Asscher cuts have large, open tables. If you are searching for a step cut diamond, we suggest looking at those with clarity grades of VS2 or higher.

WHAT IS DIAMOND COLOUR?

This grade refers to the pure white colour of a diamond, or its lack of colour.

The less colour within the diamond, the rarer and more valuable it is likely to be. While D to F colour grades are considered colourless, an untrained eye cannot easily spot colour within G to I grades. If you are concerned about visible colour and are considering platinum or white gold for the ring, Michael Arthur recommends D to G to make sure no slight colour is detected.

WHAT IS DIAMOND CARAT WEIGHT?

Carat weight is a measure of a diamond’s weight, and a reflection of its size.

1 carat is equivalent to 200 milligrams. Because carat is a record of a diamond’s weight, not its size, two diamonds of slightly different sizes may have the same carat weight. A diamond’s size also depends on how evenly its weight is distributed and the quality of its cut. Some diamonds are cut to maximise carat weight, resulting in less sparkle. A balance of quality in carat and cut is therefore recommended. Speak to Michael Arthur to discuss the ideal proportions for the diamond weight and shape you are considering.

WHAT IS DIAMOND CUT?

A quality cut grade allows a diamond to express its natural sparkle and beauty.

Cut refers to the quality of a diamond’s proportions and symmetry, and also to its shape, such as brilliant cut or princess cut.

These angles allow the diamond to capture light and reflect it, producing sparkle. If a diamond’s pavilion is too deep, for example, the centre will be noticeably dark, and if it is too shallow the diamond will leak light, reducing its performance.

If you want a truly brilliant diamond, consider those with cut grades of Excellent or Very Good. Michael Arthur Diamonds only deals in diamonds with a cut grading of Very Good or Excellent.

Each diamond comes with a GIA report, which contains a full scientific and unbiased assessment of your diamond’s 4Cs. GIA tests every diamond submitted to establish its authenticity as a diamond and whether it has been subjected to treatments. GIA reports provide a full description of the diamond, including colour, weight, measurements and cutting style, and disclose any known treatments.

A GIA diamond is a diamond graded by the Gemological Institute of America (GIA), the creator of the 4Cs and the leading independent diamond authority. Learn more about GIA and why savvy shoppers rely on it.

Fluorescence is the glow you sometimes see when an object emits visible light. Some diamonds fluoresce when they are exposed to ultraviolet (UV) rays from sources like the sun and fluorescent lamps. This can cause them to emit a bluish light or, more rarely, a yellow or orange light. Once the UV light source is removed, the diamond stops fluorescing. We work with diamonds that have nil to strong fluorescence and ensure there are no negative effects on their appearance.

Every piece of diamond jewellery we produce at Michael Arthur is certified and conflict-free.

This means we purchase them from clean, legitimate sources we know and trust, who operate under the Kimberley Process Certification Scheme and the System of Warranties.

This is serious behind-the-scenes work to ensure all diamonds Michael Arthur Diamonds provides you with are purchased under the highest ethical standards.

This international scheme was established and implemented by the United Nations in 2003 to eliminate the trade of conflict diamonds (also known as ‘blood’ diamonds):

It outlines the regulations and requirements that help prevent all forms of illegal diamond trading.

It guarantees that any imported diamonds come with government-validated Kimberley Process certificates stating the diamonds are conflict-free.

It confirms all diamonds have been transported from the source in sealed, tamper-resistant containers.

Kimberley Process members account for approximately 99% of the global production of rough diamonds.

The System of Warranties

The System of Warranties is the diamond industry’s process to further guarantee that any diamonds that make their way to individual jewellers are conflict-free. When diamonds are imported into a country and are ready for trade, they are certified by laboratories such as GIA, HRD or DCLA, which can guarantee that the stones are conflict-free. Diamond dealers can provide warranty statements guaranteeing that loose diamonds, or complete diamond jewellery, came from a legitimate source and are conflict-free.

All diamond traders and manufacturers must keep copies of their invoices for annual audits.
