About this 0.5ct natural emerald diamond

This 0.5ct natural emerald sits in the half to three-quarter 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 1428651794. Listed at 23 retailers as of October 27, 2026, with prices from £459 to £1,155, a £696 spread on the same certified stone. MOH London lists it at £1,155. 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.
