About this 1.22ct natural marquise diamond

This 1.22ct natural marquise sits in the classic one-carat band, graded K 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 6551871464. Listed at 13 retailers as of November 4, 2026, with prices from $2,613 to $4,255, a $1,642 spread on the same certified stone. Wholesale Diamonds Direct lists it at $4,255. 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.
