About this 1.23ct natural emerald diamond

This 1.23ct natural emerald sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556956116. Listed at 5 retailers as of November 5, 2026, with prices from $2,323 to $2,794, a $471 spread on the same certified stone. Blue Nile lists it at $2,794. 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.
