About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2487530131. Listed at 18 retailers as of October 31, 2026, with prices from $3,595 to $8,574, a $4,979 spread on the same certified stone. NZ Jewellers lists it at $8,574. 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.
