This 1.01ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG788669054 or 788669054. Listed at 24 retailers as of October 30, 2026, with prices from £131 to £834, a £702 spread on the same certified stone. Reve Diamonds lists it at £834. 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.
