About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555193668. Listed at 7 retailers as of October 30, 2026, with prices from £1,188 to £3,179, a £1,991 spread on the same certified stone. NZ Jewellers lists it at £3,179. 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.
