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 $5,008 to $11,573, a $6,565 spread on the same certified stone. NZ Jewellers lists it at $11,573. 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.
