This 0.54ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845658669 or 845658669. Listed at 14 retailers as of November 3, 2026, with prices from £127 to £778, a £650 spread on the same certified stone. Reve Diamonds lists it at £778. 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.
