About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 754512154. Listed at 21 retailers as of October 30, 2026, with prices from £2,732 to £5,889, a £3,158 spread on the same certified stone. NZ Jewellers lists it at £5,889. 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.
