About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6545916869. Listed at 17 retailers as of November 5, 2026, with prices from $6,207 to $14,345, a $8,137 spread on the same certified stone. NZ Jewellers lists it at $14,345. 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.
