About this 0.64ct natural oval diamond

This 0.64ct natural oval sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1505335744. Listed at 16 retailers as of November 5, 2026, with prices from $646 to $3,224, a $2,578 spread on the same certified stone. NZ Jewellers lists it at $3,224. 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.
