About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1537529474. Listed at 20 retailers as of October 27, 2026, with prices from $2,657 to $8,717, a $6,060 spread on the same certified stone. NZ Jewellers lists it at $8,717. 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.
