About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6425854156. Listed at 19 retailers as of November 5, 2026, with prices from $3,788 to $11,029, a $7,241 spread on the same certified stone. NZ Jewellers lists it at $11,029. 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.
