About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1488773530. Listed at 2 retailers as of November 2, 2026, with prices from $1,805 to $3,281, a $1,475 spread on the same certified stone. Yorxs lists it at $3,281. 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.
