About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic 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 1549827419. Listed at 11 retailers as of November 5, 2026, with prices from $7,899 to $12,198, a $4,298 spread on the same certified stone. Cape Diamonds lists it at $12,198. 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.
