About this 1.06ct natural heart diamond

This 1.06ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 801638041. Listed at 10 retailers as of October 30, 2026, with prices from $1,041 to $2,650, a $1,609 spread on the same certified stone. NZ Jewellers lists it at $2,650.
