About this 1.02ct natural marquise diamond

This 1.02ct 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 1246028134. Listed at 10 retailers as of November 5, 2026, with prices from $1,305 to $4,334, a $3,029 spread on the same certified stone. NZ Jewellers lists it at $4,334. 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.
