About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 3515444026. Listed at 8 retailers as of October 28, 2026, with prices from $17,787 to $47,241, a $29,454 spread on the same certified stone. Diamond Quarter lists it at $47,241. 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.
