Carat
Diamond carat (ct) measures a diamond’s weight, with 1 carat equal to 200 milligrams. Carat should not be confused with visible size, as two diamonds of the same weight can look different depending on their shape, cut and proportions. Dimensions are often a better guide to how large a diamond will appear, while higher carat weights generally also come with higher prices.​

A diamond's polish refers to the smoothness of its facet surfaces after cutting. Excellent or Very Good polish means the cutter's wheel has left no visible marks, allowing light to pass in and out cleanly. Poor polish can dull a diamond's brilliance, so it's worth looking for the highest grade your budget allows.

Symmetry
Symmetry describes how precisely a diamond's facets align and mirror one another. Well-symmetrical diamonds reflect light more evenly, maximising sparkle and fire. Minor symmetry variations are often invisible to the naked eye, but Excellent or Very Good symmetry ensures the diamond performs at its best.

Depth %
Depth percentage is the height of a diamond from table to culet, expressed as a proportion of its width. The ideal range varies by shape, but getting it right is critical, too shallow and light escapes through the bottom, too deep and it leaks out the sides. Both reduce brilliance.

Table %
The table is the large flat facet on top of a diamond. Table percentage measures it as a proportion of the diamond's overall width. A well-proportioned table directs light deep into the stone and back to your eye, contributing significantly to a diamond's brilliance and visual impact.

L:W Ratio
Length to width ratio compares a diamond's longest dimension to its shortest, giving you a sense of its outline. A ratio of 1.00 means a perfectly square stone, higher numbers produce a more elongated look. Personal preference rules here, whether you love a classic square or a slender, elegant shape, the choice is yours.

Fluorescence
Some diamonds emit a soft glow, usually blue, under ultraviolet light. In most cases, fluorescence has little effect on appearance in daylight and can even make faint-colour diamonds look whiter. Strong fluorescence occasionally gives a diamond a slightly hazy look, so it's worth considering alongside colour grade.
More than seventy percent of all diamonds sold by wholesalers are round brilliant cuts. Their demand lies in their excellent appearance and the excellent sparkle and brilliance that the facets produce. Round gems hold timeless charm and stand out in all setting fashions.
Their clever shape makes the round brilliant, ideal for usual solitaire settings and jewellery. As round diamonds offer the most brilliance, they stand alone well without the necessity for other side stones to provide them up. Round brilliant cuts also complement coloured stones great, as the brilliant-cut radiates the most sparkle, reflecting the full rainbow of colours to complement any gem.
Certification
All the loose diamonds that you see in our online inventory come with the original GIA Grading certificate, which is the most trusted grading report in the world. Most diamonds are laser inscribed on the girdle with their identification sign for your peace of mind. GIA provides the best help with their clarity grades. Still, it is essential to know that each buyer will have an individual desire. The catalogue provides a universal guide for deciding clarity in round diamonds.
Shop round-cuts for diamond rings
Round diamonds have been favoured for hundreds of years, and the round-brilliant cut remains at the top selection for engagement rings. The brilliance and sparkle excited from the numerous facets of the cut let the round brilliant work in every setting type — from solitaires to adorned halos round engagement rings.
Round diamonds cost higher on a per carat base than fancy shapes for two purposes; the request for round diamonds is very big, and the yield is relatively moderate. Because more of the rough gem is lost in the cutting of a round diamond, the price of each carat maintained is more expensive. A regular round diamond (for example; a 1.00 carat, F-color, VS2-clarity, Ex cut) may cost 25-35% more than a comparable fancy shape.
The appearance classification of a round cut diamond regards to how much yellow tone (or lack of a yellow tone) the diamond displays. More petite round hides shade better than larger rounds , so depending on the measurement of diamond you buy, you may not need to get a colourless (D-F) diamond, even if you want your diamond to seem colourless. We will help you choose the shade of Round diamond to purchase based on if you require a transparent diamond, a diamond with a slight tone, or a warmer diamond.
