The Marquise Cut Diamond

History of the marquise cut

Some people know the Marquise cut diamond as the “Navette” shape. This means “little boat”. Viewed from above, this shape resembles the hull of a boat. Believe it or not, but the Marquise Cut is actually inspired by lips. In the 18th century, King Louis XV of France had an official mistress: the Marquise Madame Pompadour. She was an intelligent and well-educated woman. But one of her other characteristics captivated the king: her lips. marquise diamond cut on woman's lips That’s why the king requested his Royal jeweler to design a diamond shape that looked like his mistress's lips. Over time, the diamond cut evolved to its current shape and the one you see here.

Like every diamond cut, the marquise has advantages and disadvantages.

Pros of the marquise cut

Let’s start with the benefits of this diamond shape. Besides the fact that it makes your finger looks more slender, you also get more diamond for your money. While the carat for a marquise and – for example – a brilliant are the same, the marquise looks bigger. That’s because of its long shape.

Marquises have the tendency to get a bow tie effect. The bow tie effect is something that affects several diamond shapes. When polished incorrectly, a shadow shaped like a bow tie casts over the middle section of the stone. It’s a matter of personal taste, but many people don’t like it. Another thing to keep in mind is that the ends of the marquise are fragile. If not protected, they chip easily. So either you have to be very careful with it, or purchase a marquise cut diamond with protected edges. This can be with prongs but also by means of a halo around it.
