About this 0.68ct lab-grown marquise diamond

This 0.68ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844621594 or 844621594. Listed at 17 retailers as of October 30, 2026, with prices from £213 to £988, a £775 spread on the same certified stone. Reve Diamonds lists it at £988. 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.
