About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7556984717. Listed at 13 retailers as of November 6, 2026, with prices from £2,433 to £4,914, a £2,481 spread on the same certified stone. Wholesale Diamonds Direct lists it at £4,914. 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.
