About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555051331. Listed at 7 retailers as of October 30, 2026, with prices from $1,321 to $3,477, a $2,156 spread on the same certified stone. NZ Jewellers lists it at $3,477. 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.
