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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1159166396. Listed at 11 retailers as of October 30, 2026, with prices from £6,162 to £10,651, a £4,489 spread on the same certified stone. NZ Jewellers lists it at £10,651. 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.
