About this 0.5ct natural oval diamond

This 0.5ct natural oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566528299. Listed at 21 retailers as of November 5, 2026, with prices from $704 to $3,168, a $2,464 spread on the same certified stone. NZ Jewellers lists it at $3,168. 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.
