About this 1.62ct lab-grown marquise diamond

This 1.62ct lab-grown marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG425067445 or 425067445. Listed at 11 retailers as of October 30, 2026, with a 117% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
