About this 1.4ct natural radiant diamond

This 1.4ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557214071. Listed at 13 retailers as of October 27, 2026, with prices from £2,433 to £4,770, a £2,337 spread on the same certified stone. NZ Jewellers lists it at £4,770. 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.
