About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1136074301. Listed at 6 retailers as of November 6, 2026. 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.
