About this 0.53ct natural oval diamond

This 0.53ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566378658. Listed at 4 retailers as of November 6, 2026, with prices from $528 to $759, a $231 spread on the same certified stone. Steven Stone lists it at $759. 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.
