About this 0.63ct natural emerald diamond

This 0.63ct natural emerald sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556370960. Listed at 5 retailers as of October 30, 2026, with prices from £456 to £578, a £122 spread on the same certified stone. Blue Nile lists it at £578. 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.
