About this 1.04ct natural marquise diamond

This 1.04ct natural marquise sits in the classic one-carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558437117. Listed at 5 retailers as of November 3, 2026, with prices from $2,058 to $5,020, a $2,961 spread on the same certified stone. NZ Jewellers lists it at $5,020. 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.
