Gemstone Shapes, Cuts and Descriptions

Cabochon Cut  

Cabochon cut shape is rounded on the top and flat on the bottom. The gemstone cut known as cabochon is one of the most ancient methods of cutting gem stones. Cabochon Cutting is amongst the oldest forms of cutting.  The translucent honey-yellow to greenish or brownish yellow chatoyant chrysoberyl which, when cut with a cabochon show a mobile streak of light are called as cymophane or cat's eye chrysoberyl. Among the gem stones commonly cut in this fashion also are the star sapphire, star gem stones and the star ruby.


Step Cut 

Step cut has rows of facets that resemble the steps of a staircase. A step cut gem has sloping, four-sided elongated facets that are cut below the table and run parallel to the stone’s girdle.  Step cut stones are generally not as bright and never as fiery as brilliant cut stones, but rather accentuate a gemstone's clarity, whiteness, and lustre.


Mixed Cut 

Mixed cut is frequently used for rubies, sapphires and other coloured gems. It includes faceting elements from both the brilliant and step cut techniques.  Mixed cuts combine the beauty of the Emerald cut with sparkle of the brilliant cut.


Trilliant Cut 

 A trilliant cut is a type of gemstone cut, which is triangular, as the name suggests. It is sometimes called trillion, or trillian.   The cut comes in two different variations, with curved and un-curved sides. usually with 43 or more facets. Because of their equilateral form, trilliants return substantial light and colour to the eye.


Baguette Cut 

Baguette Cut is one of the earliest and simplest cuts employed to give gems their perfect shapes.   Diamonds with baguette cut generally look longer and also resemble emeralds in shape.  If you are looking for heavy diamonds, then you can go for Baguette Cut Diamonds because they are known to be heavier than the other machine cut diamonds.


Half-Moon Shape 

Half-moon shape have a straight edge on one side and curved side on the other.  The early gemstones cutters shaped halfmoons gems from broken rounds and ovals.  A well cut halfmoon shaped stone will show brightness and sparkle from end to end.  Halfmoons are now a popular choice for side stones with cushion cut rings.


Hexagon Cut 

A hexagon is a polygon with six edges and six vertices. The total of the internal angles of any hexagon is 720 degrees.   A hexagonal gemstone cut into a brilliant gem gives the gemstone a unique look.


Checkerboard Cut 

The checkerboard cut is a technique where the gem stone is cut into a multitude of square facets spaced regularly around the stones surface.   Checkerboard gem cuts create amazing sparkle. This type of gem stone cut is commonly used for garnet, topaz, citrine, amethysts or semi-prescious stones.


Rose Cut 

Various forms of the rose cut have been in use since the mid-16th century. It is a variation of the cabochon where flat facets are polished into the curved surface of the cabochon cut stone.   Rose cuts are seldom seen nowadays, except in antique jewellery.


Brilliant Cut 

Brilliant cut include the oval, marquise or navette , heart, triangular trillion (also trillian or trilliant), and the pear or drop cuts. It takes best advantage of the optical properties of the stone and produce a finished gem with the maximum fire and brilliancy.  Brilliant cuts look the most like round brilliants and are therefore the most saleable. It is the most popular style of faceting for diamonds.
