About this 0.4ct natural emerald diamond

This 0.4ct natural emerald sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6535542779. Listed at 6 retailers as of October 30, 2026, with prices from £173 to £268, a £95 spread on the same certified stone. 77 Diamonds lists it at £268. 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.
