About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1569499512. Listed at 14 retailers as of October 27, 2026, with prices from £1,156 to £2,109, a £953 spread on the same certified stone. Helzberg Diamonds lists it at £2,109. 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.
