About this 1.21ct natural emerald diamond

This 1.21ct natural emerald sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1499035189. Listed at 12 retailers as of October 28, 2026, with prices from £3,791 to £7,107, a £3,316 spread on the same certified stone. MOH London lists it at £7,107. 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.
