About this 1.4ct natural round diamond

This 1.4ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6485964199. Listed at 11 retailers as of November 4, 2026, with prices from $12,211 to $19,018, a $6,807 spread on the same certified stone. MOH London lists it at $19,018. 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.
