About this 1.33ct lab-grown marquise diamond

This 1.33ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG538274065 or 538274065. Listed at 23 retailers as of November 2, 2026, with prices from £199 to £990, a £791 spread on the same certified stone. MOH London lists it at £990. 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.
