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 LG780623029 or 780623029. Listed at 3 retailers as of October 30, 2026, with prices from £749 to £990, a £242 spread on the same certified stone. The Diamond Guys 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.
