About this 1.54ct natural marquise diamond

This 1.54ct natural marquise sits in the one-and-a-half to two 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 1548723544. Listed at 6 retailers as of November 2, 2026, with prices from $6,566 to $11,108, a $4,542 spread on the same certified stone. NZ Jewellers lists it at $11,108. 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.
