About this 1.8ct natural marquise diamond

This 1.8ct natural marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556449520. Listed at 16 retailers as of November 4, 2026, with prices from £16,185 to £26,537, a £10,352 spread on the same certified stone. MOH London lists it at £26,537. 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.
