About this 3.7ct lab-grown marquise diamond

This 3.7ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG848620748 or 848620748. Listed at 10 retailers as of October 30, 2026, with prices from $1,735 to $6,285, a $4,550 spread on the same certified stone. Taylor and Hart lists it at $6,285. 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.
