About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1533156533. Listed at 17 retailers as of October 30, 2026, with prices from $6,027 to $13,057, a $7,030 spread on the same certified stone. NZ Jewellers lists it at $13,057. 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.
