About this 0.5ct natural oval diamond

This 0.5ct natural oval sits in the half to three-quarter carat band, graded I 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 6555563039. Listed at 24 retailers as of October 27, 2026, with prices from $600 to $3,133, a $2,534 spread on the same certified stone. NZ Jewellers lists it at $3,133. 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.
