About this 0.4ct lab-grown marquise diamond

This 0.4ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG720536217 or 720536217. Listed at 15 retailers as of October 27, 2026, with prices from $125 to $808, a $683 spread on the same certified stone. Flawless Fine Jewelry lists it at $808. 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.
