This 1.18ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG733574269 or 733574269. Listed at 17 retailers as of October 28, 2026, with prices from £134 to £1,232, a £1,097 spread on the same certified stone. Brilliant Earth lists it at £1,232. 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.
