About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6565111898. Listed at 11 retailers as of November 2, 2026, with prices from $11,655 to $21,318, a $9,662 spread on the same certified stone. With Clarity lists it at $21,318. 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.
