About this 1.02ct lab-grown marquise diamond

This 1.02ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG789603005 or 789603005. Listed at 19 retailers as of October 30, 2026, with prices from £119 to £793, a £674 spread on the same certified stone. Reve Diamonds lists it at £793. 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.
