Lab Grown Marquise Diamonds
A marquise is an elongated brilliant with a point at each end. Of every shape in the range it covers the most finger per carat, so it gives the largest apparent size for the weight, and its outline elongates the hand.
Use the filters above to narrow this lab grown marquise inventory by carat, colour, clarity and cut. Prices move with live supply, so the stone you are looking at is the stone available today, and every one is sold loose with its grading report.
Choosing a marquise diamond
Check the two points align and the two sides mirror each other, because asymmetry shows immediately on a shape this elongated. Watch for a bow-tie through the centre, and protect both points with v-shaped claws. A length to width ratio near 1.85 to 2.10 is where most buyers land.
Lab grown or natural marquise?
Every stone on this page is lab grown. If you want to price the same marquise stone as a mined diamond, the same carat, colour, clarity and cut is listed in our natural marquise diamonds, and the difference between the two is the clearest way to decide which you actually want. Both are real diamonds; the lab grown stone simply lets the same budget go further on size.
Other shapes and the full range
If you are still deciding on outline, compare this against lab grown oval diamonds, lab grown pear shaped diamonds, lab grown heart shaped diamonds. The whole lab grown diamond inventory lists every shape side by side with the same filters. To see natural and lab grown stones together along with the current specials, go to our the complete range of loose stones.
Frequently asked questions
What should I look for in a marquise diamond?
Check the two points align and the two sides mirror each other, because asymmetry shows immediately on a shape this elongated. Watch for a bow-tie through the centre, and protect both points with v-shaped claws. A length to width ratio near 1.85 to 2.10 is where most buyers land.
Are lab grown marquise diamonds real diamonds?
Yes. A lab grown diamond is the same carbon crystal as a mined one, with the same hardness and the same optical properties, and the two cannot be told apart by eye. Every stone here carries an independent grading report that names it as laboratory grown and a laser inscription on the girdle matching that report.
Can I have a marquise diamond set into a ring?
Yes. Every lab grown marquise diamond here is sold loose, so you choose the stone first and the setting second. Diamond Story sets loose stones into engagement rings, pendants and earrings in our Melbourne workshop, and we will advise on the setting that suits the shape you have chosen.
