About this 0.92ct lab-grown marquise diamond

This 0.92ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG809683405 or 809683405. Listed at 7 retailers as of October 27, 2026, with a 95% 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.
