About this 1.48ct lab-grown marquise diamond

This 1.48ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG802620398 or 802620398. Listed at 6 retailers as of November 1, 2026, with prices from £185 to £867, a £682 spread on the same certified stone. Rare Carat lists it at £867. 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.
