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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1199023568. Listed at 8 retailers as of October 28, 2026, with prices from £1,554 to £3,767, a £2,214 spread on the same certified stone. Yorxs lists it at £3,767. 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.
