About this 1.31ct natural marquise diamond

This 1.31ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567550668. Listed at 7 retailers as of October 30, 2026, with prices from $3,280 to $4,690, a $1,410 spread on the same certified stone. Jared lists it at $4,690. 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.
