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 €2,463 to €5,736, a €3,272 spread on the same certified stone. NZ Jewellers lists it at €5,736. 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.
