Loose Diamonds



In order to choose the perfect diamond for your  jewellery piece there are important factors to consider and understand.

Each diamond is unique and is a phenomenon of time, place and change. And each has specific qualities that establish its value.

The four main components to the 4 characteristics of a diamond are Cut, Colour, Clarity, and Carat. When looking at a diamond, the eye perceives a balance of its characteristics and components.


The colour evaluation of most gem-quality diamonds is based on the absence of colour. A pure and structurally perfect diamond has no hue, like a drop of water, and therefore, a higher value. We have a GIA’s certified D-to-Z colour-grading system, measuring the degree of colourlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones of established colour value.

Many of these colour distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price. This is why we’re also experts at valuing jewellery.


Natural diamonds are the result of carbon exposed to remarkable heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’

Evaluating diamond clarity involves using the GIA Clarity Scale that has 6 categories, some of which are divided into a total of 11 specific grades. Many inclusions and blemishes are too tiny to be seen by anyone other than a trained diamond grader.

This is why expert and accurate assessment of clarity is extremely important. While no diamond is perfectly pure, the closer it comes, the higher its value. We will ensure the highest diamond quality and most accurate valuation.


Diamond carat is often misunderstood and refers to a diamond’s weight, not its size. When associating diamond carat sizes, take a diamond’s cut into consideration as well: a high-carat diamond with a poor cut grade may look smaller, often cut deeper, than a diamond with smaller carat weight and a better cut. Use our diamond buying tips, diamond carat size chart, and expert tips to help you choose the best diamond carat weight for you.


For superior brilliance, choose a diamond with a  cut grade of very good or excellent for round diamonds, and good or better in fancy shape diamonds. When choosing a diamond in this range, make sure its symmetry and polish are very good or excellent, so that the impact of the above average cut is not obscured.
