About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded D 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 2504288357. Listed at 22 retailers as of October 30, 2026, with prices from £1,223 to £3,429, a £2,207 spread on the same certified stone. NZ Jewellers lists it at £3,429. 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.
