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 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 $8,072 to $10,812, a $2,740 spread on the same certified stone. Yorxs lists it at $10,812. 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.
