About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 305829106. Listed at 12 retailers as of November 5, 2026, with prices from £2,677 to £5,234, a £2,557 spread on the same certified stone. NZ Jewellers lists it at £5,234. 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.
