About this 0.52ct natural oval diamond

This 0.52ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2518269850. Listed at 13 retailers as of October 27, 2026, with prices from £337 to £1,399, a £1,062 spread on the same certified stone. NZ Jewellers lists it at £1,399. 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.
