About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded D 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 1545915029. Listed at 19 retailers as of November 5, 2026, with prices from $2,362 to $6,521, a $4,159 spread on the same certified stone. NZ Jewellers lists it at $6,521. 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.
