About this 0.55ct natural marquise diamond

This 0.55ct natural marquise sits in the half to three-quarter carat band, graded H 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 6442135615. Listed at 19 retailers as of November 5, 2026, with prices from $678 to $2,895, a $2,217 spread on the same certified stone. NZ Jewellers lists it at $2,895. 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.
