About this 0.91ct natural emerald diamond

This 0.91ct natural emerald sits in the just-under-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 6551231374. Listed at 6 retailers as of October 28, 2026, with prices from £996 to £1,507, a £512 spread on the same certified stone. GemTrove lists it at £1,507. 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.
