About this 5.03ct natural oval diamond

This 5.03ct natural oval sits in the over five carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2121245151. Listed at 9 retailers as of October 31, 2026, with prices from $301,816 to $534,738, a $232,923 spread on the same certified stone. MOH London lists it at $534,738. 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.
