About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2427329524. Listed at 17 retailers as of November 2, 2026, with prices from $11,339 to $25,909, a $14,570 spread on the same certified stone. NZ Jewellers lists it at $25,909. 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.
