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 E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG790612520 or 790612520. Listed at 5 retailers as of October 28, 2026, with prices from £193 to £805, a £612 spread on the same certified stone. Rare Carat lists it at £805. 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.
