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 G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6512955939. Listed at 18 retailers as of October 30, 2026, with prices from £6,630 to £12,469, a £5,839 spread on the same certified stone. NZ Jewellers lists it at £12,469. 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.
