About this 1ct natural emerald diamond

This 1ct natural emerald sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6415318930. Listed at 16 retailers as of November 4, 2026, with prices from £990 to £2,890, a £1,900 spread on the same certified stone. NZ Jewellers lists it at £2,890. 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.
