About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231035274. Listed at 4 retailers as of November 4, 2026, with prices from £3,731 to £5,210, a £1,478 spread on the same certified stone. 77 Diamonds lists it at £5,210. 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.
