About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7551404677. Listed at 5 retailers as of November 2, 2026, with prices from £2,729 to £4,685, a £1,956 spread on the same certified stone. Wholesale Diamonds Direct lists it at £4,685. 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.
