About this 1.5ct natural heart diamond

This 1.5ct natural heart 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 IGI 831624566. Listed at 5 retailers as of October 30, 2026, with prices from $4,532 to $8,523, a $3,991 spread on the same certified stone. NZ Jewellers lists it at $8,523. 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.
