About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 16145824. Listed at 5 retailers as of November 4, 2026, with prices from £2,552 to £5,666, a £3,114 spread on the same certified stone. MOH London lists it at £5,666. 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.
