This 2.03ct lab-grown marquise sits in the two to three carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838647708 or 838647708. Listed at 10 retailers as of October 30, 2026, with prices from £263 to £2,336, a £2,073 spread on the same certified stone. Do Amore Diamonds lists it at £2,336. 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.
