About this 15.18ct natural oval diamond

This 15.18ct natural oval sits in the over five carat band, graded F 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 5241043347. Listed at 6 retailers as of October 31, 2026, with prices from £548,840 to £718,952, a £170,112 spread on the same certified stone. Ritani lists it at £718,952. 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.
