Marquise Cut Diamonds: As Unique as the Smile of Marquise de Pompadour

As with many of the fancy shaped diamonds, the marquise is a fascinating cut with an ardent presence. This canoe-shaped diamond must be carefully chosen by the diamond cutter because of its unusual geometry. Its beauty dates back to King Louis XIV, who desired a diamond shaped like the smile of his mistress, the Marquise de Pompadour. The most important thing to remember when choosing this sophisticated cut is the length-to-width ratio to avoid a bow-tie effect.
