About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-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 6542872409. Listed at 22 retailers as of October 25, 2026, with prices from £1,777 to £4,090, a £2,313 spread on the same certified stone. MOH London lists it at £4,090. 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.
