About this 1.61ct natural round diamond

This 1.61ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA. Listed at 3 retailers as of October 31, 2026, with prices from £8,938 to £11,179, a £2,241 spread on the same certified stone. Blue Nile lists it at £11,179. 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.
