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 $682 to $2,618, a $1,936 spread on the same certified stone. NZ Jewellers lists it at $2,618. 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.
