About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three 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. Listed at 7 retailers as of October 30, 2026, with prices from $22,439 to $34,999, a $12,560 spread on the same certified stone. NZ Jewellers lists it at $34,999. 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.
