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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1565330333. Listed at 5 retailers as of October 28, 2026, with prices from £3,800 to £4,587, a £786 spread on the same certified stone. Blue Nile lists it at £4,587. 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.
