About this 0.52ct natural emerald diamond

This 0.52ct natural emerald sits in the half to three-quarter carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 815675417. Listed at 12 retailers as of November 2, 2026, with prices from £186 to £990, a £803 spread on the same certified stone. NZ Jewellers lists it at £990. 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.
