About this 0.42ct natural emerald diamond

This 0.42ct natural emerald sits in the sub-half-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6183601992. Listed at 2 retailers as of October 31, 2026, with prices from £508 to £603, a £95 spread on the same certified stone. Yorxs lists it at £603. 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.
