About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231574816. Listed at 10 retailers as of November 4, 2026, with prices from $16,697 to $26,309, a $9,612 spread on the same certified stone. NZ Jewellers lists it at $26,309. 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.
