About this 1.24ct lab-grown marquise diamond

This 1.24ct lab-grown marquise sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG602342037 or 602342037. Listed at 5 retailers as of October 26, 2026, with prices from $282 to $978, a $696 spread on the same certified stone. MOH London lists it at $978. 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.
