About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3435367873. Listed at 5 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.
