This shape has set the standard for all other diamond shapes, and accounts for more than 75% of diamonds sold today. Its 58-facet cut, divided among its crown (top), girdle (widest part) and pavilion (base), is calibrated through a precise formula to achieve the maximum in fire and brilliance. Round cut diamonds are incredibly versatile,

There are many ideal cuts or sets of proportions and facet angles for the round brilliant cut. Below are the proportions for a brilliant in percentages of girdle diameter according to the IDC (International Diamond Council formed in 1979)

Criteria	Unusual	Good	Very Good	Good	Unusual
Crown Angle	< 26.9	27.0 to 30.6	30.7 to 37.7	37.8 to 40.6	40.7 +
Pavilion Angle	< 38.4	38.5 to 39.5	39.6 to 42.2	42.3 to 43.1	43.2 +
Table width	71%+	70% to 67%	66% to 53%	52% to 51%	< 50%
Crown height	< 8.5%	9% to 10.5%	11% to 16%	16.5% to 18%	18.5% +
Girdle thickness	extremely thin	very thin	thin & medium	thick & V thick	extremely thick
Pavilion Depth (for pointed culet)	< 39.5%	40% to 41%	41.5% to 45%	45.5% to 46.5%	47%+
Culet Size			pointed to 1.9%	2% to 3.9%	4%+
Total depth	< 52.9%	53.0% to 55.4%	55.5% to 63.9%	64% to 66.9%	67.0%+

Cut Ratio

It can be seen therefore that a ratio can be realised for any given brilliant cut diamond, and which when calculated, will yield its deviation from the 100% brilliance of the Eulitz Cut (mathematically perfect). We can calculate this for you when you purchase a diamond from us and it indicates mathematically how well your diamond has been cut. We generally reject stones that fall below 9% deviation. You might think this is a hard line approach, but we want you to be delighted and so we always aim to supply you with diamonds that exceed your expectations.

Types of Brilliant cut:

The 'Ideal' round brilliant cut has changed through out history, but in 1972 Euliz calculated the proportions necessary for 100% brilliance in a diamond. We are currently translating the work from German and will provide more information on the solution in the near future.

Round cut diamonds are incredibly versatile and round cut diamond rings are the immensely popular brilliant cut. Also referred to as the “ideal cut,” or "brilliant cut" the round cut is the most famous throughout 7000 years of jewelry history. If you are looking for a diamond ring with a intense brilliance and fire, then the round cut is the only option. The current round brilliant consists on an average of 58 facets, which maximizes the amount of light that the stone reflects back. The old & traditional round cut diamonds are often characterized by a smaller table, heavy, large circular girdle, and have large depth. With new advancements in diamond cutting technology, the ideal and brilliant round has unparalleled beauty, luster, intense fire and shine. Round cut diamond ringare available in a variety of designs and styles including antique, vintage, and modern contemporary for you to choose from.

Round diamonds that are well cut are affected by variety of factors that play a important part and have an impact on the brilliance and amount of intense fire that is emitted and reflected back to viewers eyes. A good round cut diamond ring should have an excellent polish, high luster, linear and atmospheric symmetry, more facets, perfect table, girdle and pavilion alignment, and clear transparency, as do all of the round cut diamonds sold by Sndgems. All of this can be achieved and produced by a skilled, gifted and expert stone-cutter and modern advanced cutting tools, so only order a round cut diamond ring from stores that have a reputation of selling good quality as well as stylish cuts. Also, the purity of the diamond is an important aspect to consider as is purity of your eternal love. Please be beware that many jeweler stores try to sell imitated and replicated diamonds filled with artificial fillings which you wouldn't be able to dtect with naked eyes. They try to sell synthetic man made diamonds as authentic diamonds which is a big concern for you. That is why please do careful & thorough research on a store before selecting a round cut diamond ring, and always shop from a tradional & reputable jewelry like Sndgems.
