About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 734534187. Listed at 6 retailers as of October 27, 2026, with prices from $1,523 to $4,122, a $2,599 spread on the same certified stone. NZ Jewellers lists it at $4,122. 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.
