About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551617543. Listed at 9 retailers as of November 3, 2026, with prices from $1,160 to $2,245, a $1,085 spread on the same certified stone. Yorxs lists it at $2,245. 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.
