This 1.4ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836623886 or 836623886. Listed at 6 retailers as of October 28, 2026, with prices from $321 to $1,059, a $738 spread on the same certified stone. MOH London lists it at $1,059. 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.
