About this 1.23ct natural emerald diamond

This 1.23ct natural emerald sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6312215708. Listed at 16 retailers as of November 5, 2026, with prices from £1,445 to £4,073, a £2,628 spread on the same certified stone. NZ Jewellers lists it at £4,073. 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.
