About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1569227572. Listed at 11 retailers as of November 6, 2026, with prices from £1,463 to £2,978, a £1,516 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,978. 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.
