About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5563477788. Listed at 13 retailers as of October 31, 2026, with prices from £2,391 to £4,548, a £2,157 spread on the same certified stone. Helzberg Diamonds lists it at £4,548. 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.
