About this 0.8ct natural oval diamond

This 0.8ct natural oval sits in the just-under-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 6451921357. Listed at 26 retailers as of November 7, 2026, with prices from $1,945 to $6,638, a $4,694 spread on the same certified stone. NZ Jewellers lists it at $6,638. 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.
