About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555474780. Listed at 11 retailers as of October 30, 2026, with prices from $2,521 to $6,439, a $3,918 spread on the same certified stone. NZ Jewellers lists it at $6,439. 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.
