About this 5.21ct natural oval diamond

This 5.21ct natural oval sits in the over five carat band, graded G 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 2195424944. Listed at 6 retailers as of October 29, 2026, with prices from $171,774 to $280,290, a $108,516 spread on the same certified stone. MOH London lists it at $280,290. 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.
