About this 1.51ct lab-grown marquise diamond

This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG713524947 or 713524947. Listed at 17 retailers as of October 31, 2026, with prices from €546 to €1,692, a €1,146 spread on the same certified stone. Rare Carat lists it at €1,692. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
