About this 3ct natural marquise diamond

This 3ct natural marquise sits in the three to five carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6455465694. Listed at 3 retailers as of November 4, 2026, with prices from $44,191 to $67,646, a $23,455 spread on the same certified stone. MOH London lists it at $67,646. 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.
