About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551370755. Listed at 8 retailers as of November 6, 2026, with prices from $3,640 to $5,969, a $2,329 spread on the same certified stone. Wholesale Diamonds Direct lists it at $5,969. 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.
