About this 1.21ct natural oval diamond

This 1.21ct natural oval 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 5563116856. Listed at 22 retailers as of November 6, 2026, with prices from $2,120 to $6,264, a $4,145 spread on the same certified stone. NZ Jewellers lists it at $6,264. 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.
