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 1443671778. Listed at 20 retailers as of October 30, 2026, with prices from $2,900 to $6,965, a $4,065 spread on the same certified stone. NZ Jewellers lists it at $6,965. 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.
