About this 0.71ct lab-grown marquise diamond

This 0.71ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG720597483 or 720597483. Listed at 10 retailers as of October 28, 2026, with prices from $255 to $630, a $375 spread on the same certified stone. Brilliant Earth lists it at $630. 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.
