This 1.5ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 5556052378. Listed at 20 retailers as of November 5, 2026, with prices from $6,362 to $15,355, a $8,992 spread on the same certified stone. NZ Jewellers lists it at $15,355. 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.
