Celini – Engagement Ring

Enter the budget range that works for you to see which diamonds fit your search. If there are no diamonds available within your required range, you may need to adjust your Carat Weight or other diamond variables.

View either GIA or IGI diamonds, or a mixture of both. GIA are recognised as the world’s most accurate and reliable graders of natural diamonds, whilst IGI are regarded as providing the most thorough analysis of lab diamonds.

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.

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.

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.

LEARN ABOUT FLUORESCENCE

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.

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 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.
