About this 0.52ct natural emerald diamond

This 0.52ct 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 1553556385. Listed at 7 retailers as of November 4, 2026, with prices from £374 to £489, a £115 spread on the same certified stone. Blue Nile lists it at £489. 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.
