About this 1.58ct lab-grown marquise diamond

This 1.58ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG778666518 or 778666518. Listed at 21 retailers as of November 1, 2026, with prices from £187 to £960, a £773 spread on the same certified stone. With Clarity lists it at £960. 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.
