About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542671206. Listed at 12 retailers as of November 4, 2026, with prices from £1,785 to £3,152, a £1,367 spread on the same certified stone. Wholesale Diamonds Direct lists it at £3,152. 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.
