About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 7551078606. Listed at 16 retailers as of November 4, 2026, with prices from £5,631 to £11,031, a £5,400 spread on the same certified stone. NZ Jewellers lists it at £11,031. 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.
