About this 0.39ct natural emerald diamond

This 0.39ct natural emerald sits in the sub-half-carat band, graded J 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 5566318315. Listed at 3 retailers as of October 31, 2026, with prices from £178 to £231, a £52 spread on the same certified stone. 77 Diamonds lists it at £231. 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.
