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 5231946661. Listed at 2 retailers as of October 31, 2026, with prices from $5,151 to $8,680, a $3,529 spread on the same certified stone. MOH London lists it at $8,680. 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.
