About Marquise Cut Diamonds

Let's get right to the list of what makes marquise cut diamonds special and what you should look for when buying a marquise shape diamond.

  • Just like ovals, marquises will make almost any fingers look elongated and elegant.
  • They look bigger than round cut diamonds with the same weight, and they tend to be cheaper. High five!
  • Be careful when it comes to L/W Ratio with Marquises. Look for something between 1.8:1 and 2.2:1. You’ll thank me later.
  • Now the cons: Marquise cut diamonds tend to have a bow tie. I know, again. But don’t worry, you can find a Marquise with a diminished one. Just try to stick with a depth range from 58% to 64%.
  • Also, the shape of the girdle matters for a Marquise cut. If it’s too thick, a lot of space would have been wasted inside the diamond. If it’s too thin, your diamond will be extremely fragile. I suggest you look for ‘thin’ or ‘slightly’ thin only.
  • When it comes to color, Marquise cut diamonds don’t hide it that well, unlike their round counterparts, and maybe even in a more pronounced way than the other fancy cuts. I suggest you go for a G color diamond or higher.
  • But for clarity, don’t be afraid to go as low as VS2 or SI1, as long as you know where they are. Marquises are good at hiding small inclusion.
  • For grading reports, my advice is you only pick a GIA certified Marquise diamond.
