About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 1123472190. Listed at 16 retailers as of November 1, 2026, with prices from $14,325 to $26,270, a $11,945 spread on the same certified stone. NZ Jewellers lists it at $26,270. 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.
