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 6562287659. Listed at 3 retailers as of October 28, 2026, with prices from £216 to £297, a £81 spread on the same certified stone. 77 Diamonds lists it at £297. 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.
