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 7 retailers as of November 1, 2026, with prices from $1,307,001 to $1,712,103, a $405,102 spread on the same certified stone. Ritani lists it at $1,712,103. 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.
