About this 0.9ct natural oval diamond

This 0.9ct natural oval sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6445853532. Listed at 20 retailers as of November 5, 2026, with prices from $868 to $3,004, a $2,136 spread on the same certified stone. NZ Jewellers lists it at $3,004. 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.
