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 $1,046,895 to $1,371,378, a $324,483 spread on the same certified stone. Ritani lists it at $1,371,378. 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.
