About this 1ct natural emerald diamond

This 1ct natural emerald sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565790904. Listed at 10 retailers as of November 4, 2026, with prices from £985 to £1,768, a £782 spread on the same certified stone. Helzberg Diamonds lists it at £1,768. 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.
