About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 1509817064. Listed at 7 retailers as of November 5, 2026, with prices from $14,533 to $35,475, a $20,942 spread on the same certified stone. Diamond Quarter lists it at $35,475. 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.
