About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded H 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 2116107671. Listed at 4 retailers as of October 31, 2026, with prices from £2,803 to £4,142, a £1,339 spread on the same certified stone. 77 Diamonds lists it at £4,142. 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.
