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 standard cut grade stated by the retailer rather than the lab and certified by GIA 5231659519. Listed at 21 retailers as of November 4, 2026, with prices from $5,210 to $10,593, a $5,383 spread on the same certified stone. MOH London lists it at $10,593. 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.
