About this 1.2ct natural marquise diamond

This 1.2ct 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 7541945323. Listed at 13 retailers as of November 3, 2026, with prices from £3,288 to £6,440, a £3,152 spread on the same certified stone. Wholesale Diamonds Direct lists it at £6,440. 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.
