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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565491818. Listed at 14 retailers as of November 4, 2026, with prices from $3,701 to $6,587, a $2,886 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,587. 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.
