About this 1.05ct natural marquise diamond

This 1.05ct natural marquise sits in the classic one-carat band, graded J 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 1156013614. Listed at 5 retailers as of October 30, 2026, with prices from $2,439 to $6,230, a $3,791 spread on the same certified stone. NZ Jewellers lists it at $6,230. 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.
