This 0.67ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG801659930 or 801659930. Listed at 23 retailers as of October 30, 2026, with prices from £181 to £992, a £811 spread on the same certified stone. Reve Diamonds lists it at £992. 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.
