About this 0.64ct natural oval diamond

This 0.64ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522681401. Listed at 17 retailers as of October 27, 2026, with prices from $974 to $3,308, a $2,335 spread on the same certified stone. NZ Jewellers lists it at $3,308. 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.
