About this 0.83ct lab-grown marquise diamond

This 0.83ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG817672511 or 817672511. Listed at 20 retailers as of November 3, 2026, with prices from £189 to £950, a £761 spread on the same certified stone. Reve Diamonds lists it at £950. 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.
