This 0.54ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836619138 or 836619138. Listed at 16 retailers as of November 4, 2026, with prices from £200 to £1,168, a £969 spread on the same certified stone. Reve Diamonds lists it at £1,168. 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.
