About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2111067766. Listed at 2 retailers as of November 6, 2026, with prices from £2,810 to £3,831, a £1,021 spread on the same certified stone. 77 Diamonds lists it at £3,831. 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.
