About this 0.42ct natural emerald diamond

This 0.42ct natural emerald sits in the sub-half-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5234406666. Listed at 4 retailers as of November 1, 2026, with prices from £230 to £507, a £276 spread on the same certified stone. MOH London lists it at £507. 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.
