This 1.51ct natural round 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 and certified by GIA 2487987638. Listed at 16 retailers as of October 30, 2026, with prices from £2,054 to £4,782, a £2,729 spread on the same certified stone. NZ Jewellers lists it at £4,782. 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.
