About this 0.45ct natural heart diamond

This 0.45ct natural heart sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 790618448. Listed at 11 retailers as of October 30, 2026, with prices from $478 to $1,835, a $1,357 spread on the same certified stone. NZ Jewellers lists it at $1,835. 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.
