About this 1.55ct natural round diamond

This 1.55ct natural round sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 2537188581. Listed at 13 retailers as of November 4, 2026, with prices from £2,225 to £5,192, a £2,967 spread on the same certified stone. NZ Jewellers lists it at £5,192. 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.
