About this 0.71ct natural marquise diamond

This 0.71ct natural marquise sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551408877. Listed at 18 retailers as of October 30, 2026, with prices from £439 to £1,650, a £1,211 spread on the same certified stone. NZ Jewellers lists it at £1,650. 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.
