About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG842605764 or 842605764. Listed at 3 retailers as of October 27, 2026, with prices from €274 to €579, a €305 spread on the same certified stone. Taylor and Hart lists it at €579. 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.
