From emerald cut engagement rings. When grading and appraising Diamonds, cut may not be as influential as the other C’s like color, clarity, and carat weight, but it is definitely an influencing factor when it comes to the Gemstones overall beauty. To properly evaluate the cut of a given Gemstone, you must not only study its face-up view or the surface or top view but study it from all other angles as well. An excellent cut can reduce loss on carat weight but enhance its looks to breathtaking proportions at the same time.

Common Cuts Used on Gemstones

Brilliant Cuts   A brilliant-cut Gem usually has three flat polished surfaces per facet. They are positioned in such a way to radiate the best light from the Gemstone. Diamond cutters also make sure that the angles will enhance the brilliance of the Gemstone. Brilliant cuts are mostly used for Diamonds and transparent Diamonds.

Some facets will have one or more shapes like stars, hearts, kites, and lozenges. Variations of the brilliant cut include the naivet or boat-shaped marquise, per-shaped pendeloque, and oval shape. Oval shapes are suitable for Gemstones with lower carat weight because they can make them appear bigger. 

The most popular variation of all is the full-cut round brilliant. It has fifty-eight facets, presently the greatest count for brilliant cut Gemstones. The single brilliant cut, on the other hand, has seventeen to eighteen facets. For Diamonds used in earrings and pendants, the briolette variation is mostly used to provide it with circular cross-section teardrop shapes. Brilliant cuts with triangular dimensions are called trilliants while square brilliant cuts are also known as princess cuts.

Step Cuts   Another popular cut for a Gemstone is the step or trap cut. Step cuts are best used for colored Gems because they possess four-sided table facets and girdles as well as parallel quadrilateral facets. The term step cut was used because this Gemstone cut bears similarities with a staircase. Step cuts have fewer facets than brilliant cuts. 

One well-known variation of a step cut is the baguette. It is rectangular in shape but with square corners. Emerald cuts are also quite popular. Its name was derived from its consistent use with emeralds. Emerald cuts remove the corners and form an octagonal shape. Clipping off the corners protect delicate Diamonds like emeralds and facilitate setting of Diamonds at the same time. Other popular variations for step cuts are window, table, radiant, and oval.

The best advantage of step cuts is its ability to enhance a Diamonds color, making the color richer and appearing to have originated straight form the belly of the Gemstone.

Mixed Cuts   Mixed cuts for Diamonds are mostly combinations of brilliant and step cuts. The crown or top portion of a Gemstone will resemble a brilliant cut while the pavilion or bottom portion of a Gemstone will receive a step cut. At times, the two cuts will appear side by side. Mixed cuts are also characterized by their rounded outlines. Many transparent Diamonds like rubies and sapphires are often cut this way. Gemstones with mixed cuts are also commonly set in prongs. 

Variations for mixed cuts include but are not limited to cushion, zircut, pear or teardrop, and oval.

Cabochon Cuts   A Diamond with a cabochon cut will appear rounded on top and flat on the bottom. At times, Gems will only appear in this cut. Height of a Gemstones dome with a cabochon cut varies. The name is derived from the French term used for bald heads. Cabochon cuts are simplest to make, and that’s why you’ll often see them used on affordable Diamonds and those that will not benefit from faceting.

Fancy Cuts   Any other cut besides those mentioned above is usually referred to as fancy. A checkerboard cut, for instance, will have a combination of a large table facet on top and a mixed cut. A rose cut will have a round girdle outline, flat base, dome-shaped crown, and facets of a brilliant cut.

When judging the cut of a Gem, start by evaluating it face up. See if the Diamond shows uniform color distribution and radiates light in the best possible way. Gemstones cut with large windows are unappealing. Lastly, recheck all other angles and determine if the cut took both carat weight and looks into consideration.

From one of a kind princess cut engagement rings. Colored Gemstones are usually cut to make the most of the exquisiteness of the gem’s color. A high-quality cut highlights the Gem’s color, moderates its attachments and unveils superior regularity and proportion. Since Diamond color can differ, there are no rigid geometrical principles to follow to maximize the radiance of the stone. The cut of the rare Diamonds are usually done with no thought for its color.

Cut considerations

The percentage of the stone together with its gleam and exactness in faceting conclude the amount of the stones ability to exude beauty and fire. If you are to assess the significance of cutting the Diamond, you might just arrive at the thought that it is everything. The stone’s cut intensely affects the energy, brightness and vivacity together with its observed size and its plain color.

With the previously mentioned identification of the stones brilliance the cut made on it must be geometrically precise, meaning the facets of the stone must be properly aligned which would allow enough light to come in to the stone which in turn would reflect on the upper large side.   

Diamond cuts

Round brilliant cut- this is the most widely accepted surface cut for most of the Gemstones which includes Diamonds that are known for deflecting the most light. The regular round brilliant cut normally has 24 faces on its pavilion, 32 faces on its crown and a table surface. 

Cabochon cut- this cut is known for being flat on its bottom and rounded on its upper portion. This cut is known as the primogenital and a common cut, its variety includes: oval, round, triangular, and sometimes even octagonal cuts. 

Oval cut- this is the spin-off of the round brilliant cut.

Emerald cut- less deflective among all the other kinds of cut, but this is considered as the best cut for emeralds. Its variations include trillion and square.

Radiant cut- consists of 70 surfaces and is naturally rectangular in shape with small cut on its corners. When done on a Diamond, its crown corner consists of a blend of the pavilion section and the brilliant-step cut scheme. 

At the end of the day, there really is no single and standard arrangement regarding what angle to utilize for faceting the different Gems. The definition of the best cut is rather subjective for it is completely dependent on the personal preference of the person who wants the stone to be cut.
