This 1.31ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555815619. Listed at 2 retailers as of November 1, 2026, with prices from $7,383 to $9,888, a $2,506 spread on the same certified stone. Yorxs lists it at $9,888. 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.
