About this 15.04ct natural oval diamond

This 15.04ct natural oval sits in the over five carat band, graded FANCY colour (tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2225340440. Listed at 10 retailers as of November 1, 2026, with a relatively tight 22% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
