About this 1.7ct natural emerald diamond

This 1.7ct 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 1565792034. Listed at 5 retailers as of November 1, 2026, with prices from £4,419 to £5,587, a £1,169 spread on the same certified stone. Ritani lists it at £5,587. 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.
