About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6233866982. Listed at 7 retailers as of November 3, 2026, with prices from $3,085 to $6,482, a $3,397 spread on the same certified stone. NZ Jewellers lists it at $6,482. 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.
