This 1.51ct natural round sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2566054835. Listed at 14 retailers as of October 27, 2026, with prices from €3,861 to €8,450, a €4,589 spread on the same certified stone. NZ Jewellers lists it at €8,450. 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.
