Bullet
The name comes from the shape of a bullet.
Step cut bullets work well with Asscher and Emerald cut diamonds in the center.
Brilliant cut bullets will match a brilliant cut center stone, especially colored stones and colored diamonds.
Cadillac
A Cadillac Cut is a diamond with five sides. It has one long side, as a base, and two sides that taper at exactly the same angle and two more side that also taper at exactly the same angle to come to an apex point.
It's called this way because its outline is reminiscent of the famous Cadillac logo.
Cadis are the perfect side stones for center Rounds, Emeralds, Asher cuts and Cushions.
Epaulet
Epaulet is a modified 5-sided fancy cut of a diamond, somewhere between a Trapezoid and a Tapered Bullet.
It resembles a shoulder ornament in outline, and its name came from the French spelling – Epaulette.
Available in either a Step Cut or Brilliant Cut, they work well with either long or short center stones.
Half Moon
The Half Moon diamonds are used mainly for side stones and have the profile of half a round or half an oval diamond. They have a straight edge on one side and curved side on the other.
Half Moon diamonds look great with rectangular center stones such as princess, radiant or emerald because they have one straight side. They come in either step or brilliant cut.
Heart
The technical name for this stone is the “Heart-Shaped Modified Brilliant,” based upon its shape and modifications of the traditional round brilliant configuration.
Heart shaped diamonds are popular as matched pairs for stud earrings and side stones for diamond rings.
Tapered Baguette
A tapered baguette, also known as "Taper", is a relatively small, elongated diamond where the two long sides taper inward to form a long trapezoidal shape.
The word “baguette” is a French word for a long, narrow loaf of bread.
Aside from being the most common side stones used in engagement rings, the look of the tapered baguette lends itself to use as matched side stones flanking rounds, ovals, princess and other classic shapes.
Kite
The Kite Shape diamond is a fancy shape which resembles a kite, or the sectional profile of a diamond viewed from the side. It is mostly used as side stones inside the shank of a fancy ring or as side stones to a center round or rectangular.
Shield
Shield Cut diamonds are a fancy shape resembling a shield used by warriors and have a somehow look of a triangular shape diamond with the top side bowed and the two bottom sides composed of two bowed edges.
Shield cut diamonds are used as side stones for rings where their wide end is fitted next to the center stone. They can also be used for dangle earrings and pendants.
Trapezoid
Trapezoids, or "Traps" are probably the most popular side stones used in jewelry.
The term trapeze is probably derived from the flying trapeze made famous in the circus.
Trapezoids work best with elongated or very large stones. Step cut trapezoids work great with Emerald or Asscher cut, while Brilliant cut trapezoids are usually matched with radiant or princess cuts, as well as with colored diamonds and gemstones.
Trillion
Trillions are basically triangular in shape, cut into the shape of a wedge. The corners of this shape may be pointed or rounded and the body will vary depending on the stone’s characteristics and the cutter’s preference.
Trillions are most often sold as matched side stones for rings. Next in terms of volume are diamond stud earrings, followed by solitaire pendant necklaces and rings.
