About this 1.51ct lab-grown marquise diamond

This 1.51ct 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 LG784651996 or 784651996. Listed at 6 retailers as of November 3, 2026, with prices from £185 to £899, a £714 spread on the same certified stone. Frank Darling lists it at £899. 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.
