• Marquise cut. The marquise cut is a slender striking cut that designers often use for their "masterpieces". The shape allows to create a feeling that the diamond is bigger than it really is. Its length is twice bigger than its width.
• Round cut. The name suggests us that a design with this cut would contain a circle cut diamond. The circle cut diamonds have always been an excellent choice for engagement rings, despite its not-so-modern appearance. They bribe by their elegance and simplicity.
• Pear cut. One more popular fancy cut. It has the round cut in the base of the brilliant and extends itself to a point. If ideally proportioned it gives a depth of scintillation to the point of the stone. It is used if a longer look is required.
• Oval cut. Another popular diamond cut which is particularly good for rings with a wide band or with long rows of accent stones. This cut is known for its outstanding shine and sparkle which make sure that you won't be disappointed after buying it.
