Carat Weight

Carat is a measurement of a diamond’s weight, which indicates its size. Diamonds of the same carat can appear different sizes depending on its shape, and how well it’s cut. Referred to as ‘ct’, 1ct equates to 0.20g.

RPS Diamonds Recommends prioritising Cut, Colour and entering your budget to guide your Carat search.

Colour

As diamonds form, they can pick up trace elements that cause colouration - typically yellow, brown or green tints. The higher the Colour grade, the more colourless the stone. As a very visual aspect of the diamond, it is important to choose a high Colour grade for a bright and icy stone.

RPS Diamonds Recommends D to F for a bright and colourless diamond.

Clarity

Most diamonds contain small irregularities known as inclusions and blemishes, which form as the diamond grows. A high Clarity grade will drive up price, so consider diamonds that contain inclusions that you won't see with the naked eye, rather than aiming for an extremely high Clarity grade.

RPS Diamonds Recommends VS2 to SI1 for natural diamonds and VVS2 to VS2 for lab diamonds. These provide the best quality to value ratio.

Cut

The Cut grade of a diamond outlines how precisely each facet of the diamond has been cut. The better the cut, the crisper, brighter and more intense the sparkle - so it’s an important grade to prioritise. It only applies to round diamonds, so consider high symmetry and polish grades for other shapes.

RPS Diamonds Recommends Excellent for GIA graded natural diamonds, or Ideal for IGI graded lab diamonds - essentially different terms for the same, top grade.

Polish

The Polish grade of a diamond refers to the smoothness of the diamond’s facets. The higher the grade, the more finessed the Polish of the stone, meaning you won’t see imperfections like burns or abrasions, and instead the diamond will sparkle clear and bright.

RPS Diamonds Recommends Excellent to Very Good for a sparkly diamond with a clear looking surface.

Excellent

Very Good

Symmetry

Symmetry refers to the symmetrical arrangement and alignment of the diamond's facets. Diamonds require symmetry to produce the best brilliance, and it is important to see strong lines of symmetry in fancy shaped diamonds for the best aesthetics.

RPS Diamonds Recommends Excellent to Very Good for strong brilliance and perfect looking shapes.

Excellent

Very Good

Fluorescence

Diamonds with poor Fluorescence grades emit a soft glow when exposed to UV light sources, such as the sun, which can cause the diamond to look hazy. This can counteract the effect of a high Cut and Colour grade, so a diamond with no Fluorescence is favourable.

RPS Diamonds RecommendsNone to Faint for a diamond that appears crisp and bright in all lights.

Table %

The table is the top surface facet of the diamond, and is the largest of all the facets. This is the diamond’s main point of entry for light and largely determines its sparkle. An ideal table is large enough for plenty of light to enter, but not too large that it negatively impacts the dispersion of light. Different diamond shapes will have different ideal table percentages.

RPS Diamonds Recommends 52% to 62% for round diamonds.

min

max

Depth %

The depth of a diamond is its height from the tip of the culet to the table, and the percentage of the diamond’s depth can hugely impact sparkle. Diamonds cut too shallow or too deep wont produce the best sparkle and can appear dull, because the light isn’t optimally bounced from facet to facet.

RPS Diamonds Recommends 58% to 63% for round diamonds.

Ratio

Ratio refers to the length to width dimensions of the diamond, the ideal of which will vary depending on diamond shape and your personal preference. A round diamond’s ratio should be 1, meaning it is as long as it is wide. The higher the ratio, the longer and thinner the diamond.
