Gemstone's quality is greatly determined by its cut, but unlike for diamonds, there are no standardized cutting rules for all gemstones. In order to pick the perfect piece, read up on types of cuts that will bring out the best a gemstone can offer.
The cut of a gemstone can make a world of difference. To understand this, all you need to do is compare pictures of a gemstone in rough form and after it is cut. High quality cutting maximizes the natural beauty of a gemstone and minimizes the visibility of flaws.
A well-cut gemstone should have good symmetry and proportions. However, the huge variation of gemstone colors means that, unlike white diamonds, there are no set standards for cutting.
Gemstones with very saturated colors will generally be cut shallower than gemstones with less saturated color. Deeper cuts can help to intensify the pale colors, while shallow cuts can help make the color of dark stones appear more vibrant.
There are dozens of different cuts of gemstone, many of which look very similar and the best way to establish the cut is to compare it to pictures. Some are more rounded, some are square, and some can be a combination. However, one thing that they will all have in common is facets. The number of facets may also give you an indication of the gemstone’s cut.
There are many different cuts of gemstone (too many to list), and different stones are more suited for different cuts. For diamonds, for example, the most common cuts include Round Brilliant Cut, Emerald Cut, Cushion Cut, Marquise Cut, Princess Cut and Radiant Cut. The quality of the stone and personal preference are likely to determine which one you choose.
The top cut of a gem is called the crown which will have several facets (sides) on it. The largest of the horizontal facets will be called the table with the base be known as the pavilion.
All gemstones sparkle to a certain degree, but experts agree that the diamond offers the most. Of the cuts, the round brilliant cut, with its 58 facets, tends to give off the most sparkle as it allows light to reflect off every edge.
It is almost impossible to give an accurate estimate about how much it costs to get a gemstone cut as it will depend on the stone, the jeweller and the number of and style of cuts to be made. The round brilliant cut tends to be the most expensive due to the intricate detail required. Prices tend to start from $50.
