About this 5.18ct natural oval diamond

This 5.18ct natural oval sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2155817505. Listed at 3 retailers as of October 29, 2026, with prices from £122,736 to £194,769, a £72,033 spread on the same certified stone. MOH London lists it at £194,769. 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.
