Diamond rings come in all kinds of settings simple, elegant, glamorous, traditional, extravagant or totally different. The diamond ring settings for the marquise diamond do often come with a halo setting. But next to this popular marquise diamond ring setting there are some other settings that are very popular. Read on and perhaps you will be choosing for marquise engagement rings.

The elegant & timeless solitaire setting Marquise diamonds have their own strong appearance; therefore the solitaire ring setting is very popular for the marquise cut diamond. The focus will be on the marquise diamond instead of the ring setting, giving it the attention it deserves.

The halo setting To spice up the appearance of a marquise diamond a halo setting is a popular pick for marquise diamond engagement rings. The halo around the center-stone makes the appearance of the marquise diamond even larger and gives it a softer yet more glamorous appearance. Some even choose to add pave diamonds in the marquise cut diamond ring band resulting in a ring that truly sparkles away while being less usual as a round cut diamond due to the center diamond -marquise diamond.

The totally different setting This is obviously not the name of the setting but it explains what the appearance of this marquise diamond ring is: totally different. Because in this setting the marquise diamond is not mounted in the ring setting vertical, with the points up and down but horizontal. While it is just a slight change in the way it gets mounted in the ring it has a big impact visually.

Which of these three marquise diamond ring settings do you prefer most?

Quality And Grading Of Marquise Cut Diamonds

When looking at the quality of marquise cut diamonds, there are a few important factors to consider: shape, color, clarity, and cut. These aspects help determine how beautiful and valuable the diamond is.

Evaluating Diamond Shape

  • Shape: A marquise diamond should look like a football, with two pointed ends and curved sides.
  • Length-to-Width Ratio: The ideal length-to-width ratio is around 2.00. This means the diamond should be long and narrow to look balanced.
  • Symmetry: It’s important that the diamond is symmetrical. If it isn`t balanced, it can lose some of its sparkle and beauty.

Diamond Color and Clarity

  • Color: The color of a diamond is graded from D (colorless) to Z (light color). For marquise cut diamonds, a color grade of D to H is best for a bright, white appearance.
  • Clarity: Clarity looks at how clear the diamond is and if there are any flaws inside or on the surface. It`s a good idea to choose diamonds with high clarity grades like Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1 and VVS2), or Very Slightly Included (VS1 and VS2). Marquise cuts can show colors and imperfections more easily than other shapes, so higher grades are better.

Cut Parameters and Symmetry

  • Cut: The way a diamond is cut affects how it sparkles. It’s important to check the cut parameters to make sure they are in the ideal or excellent range according to the GIA or AGS.
  • Polish and Symmetry: Look for diamonds with very good or excellent polish and symmetry ratings. If a diamond has poor symmetry, it might not reflect light as well, which can reduce its sparkle.

Choosing Certified Diamonds

  • Certification: Always choose diamonds that are certified by trusted gemological institutes. Certified diamonds have been thoroughly checked by experts who provide detailed reports on their quality.
  • GIA Certification: This certification ensures that the diamond’s cut, color, clarity, and carat weight meet strict standards.
  • AGS Certification: Known for its detailed cut grading system, AGS certification is especially useful for fancy-shaped diamonds like the marquise cut.

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
