This 0.81ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6223166247. Listed at 3 retailers as of November 2, 2026, with prices from $3,520 to $5,356, a $1,836 spread on the same certified stone. 77 Diamonds lists it at $5,356. 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.
