Diamond cut is often mistaken to be the shape of the diamond, but cut refers to the proportion and alignment of the facets, symmetry, the polish of the diamond and the quality of craftsmanship. A diamond sparkles brilliantly due to its ability to reflect and interact with light and this ability is determined by the perfection in the cut.

When a diamond is cut well, light enters through the table and travels to the pavilion where it reflects from facet to facet till it is thrown back through the table to the observer’s eye. This is called the light performance of a diamond. A poorly cut diamond makes the light seep out from the sides and the bottom of the diamond and it looks dull and lifeless despite its clarity and colour grading.

So even a flawless diamond with the whitest possible colour will start to look dull and lacking shine, if it is not cut to perfection.

DIAMOND PROPORTIONS

Elements such as a diamond's width and depth are universally measured to determine the quality of a stone. According to The Diamond Pro, “Diamond cut proportions directly affect a diamond's ability to reflect light and provide brilliance. Proportions are based on the ratios between size, angle and shape of each diamond facet. Various combinations of these elements impact how the diamond will interact with light, which determines its overall beauty and lasting appeal.” There are three common width ratios of diamond: shallow, ideal and deep. Shallow cut diamonds often appear larger based on their table size; how- ever, light escapes these stones through the sides greatly impacting the diamond's brilliance, sparkle and fire. Alternatively, when a gemstone is cut too deep, white light is forced to pass through the bottom of the diamond making the stone generally less vibrant and appealing. For the best results, seek out an excel- lent or ideal cut stone. These cuts are equipped with optimal facet angles to ensure ultimate fire and brilliance.

Brilliance refers to the brightness of a diamond, created by the combination of all the white light reflected from the surface and the inside of a polished diamond. When light hits a diamond's surface, some light enters and some is reflected back. A round diamond will typically display more brilliance than a fancy shape due to the ability of the round cut to maximise the reflecting light.

Fire refers to the brilliant, colourful flashes reflected by the diamond. The fire effect is caused by the dispersion of light as it travels through the diamond. The better the cut of the diamond, the more vibrant the dispersed colours will appear.

Sparkle refers to the dance of light which is produced when a diamond is moved from side to side. These flashes are caused when the light that isn't reflected back from the table, enters the diamond and bounces off the inside walls of the diamond.

For a diamond to be magnificently brilliant, this light performance of brilliance, fire and sparkle needs to be at the maximum. ORRA Crown Stars are cut to maximise this light performance.We proudly claim that diamond is brightest and the same is evident from the GemEx certification that we git for our OCS products. GemEx certification is done for stones above 18 cents and a certificate of acceptance is issued by the GemEx lab in USA

Some of these differences are not visible to the naked eye, but directly impact the overall quality and price of the stone. Only a certified grading professional can determine a diamond’s color grade. Also the tone of the jewellery’s setting can affect the appearance of diamond color and hence the colour grading is done before setting the diamonds into jewellery. If you are buying affordable jewellery then you can go for our Astra collection which has I, J, K colors.

A common misperception is that a larger carat weight is always better than a smaller carat weight. But this needs to be in conjunction with a perfect cut. In fact, a high carat weight diamond with a poor cut may look smaller than a diamond with a smaller carat weight and a very good cut.

So having understood the above factors, choose your diamond keeping in mind how get the best value for your budget. With ORRA, you can rest assured that our diamonds are cut to ensure brilliance because without that social dazzle, a diamond has no raison d'étre.
