About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6531148030. Listed at 11 retailers as of October 30, 2026, with prices from $3,985 to $7,883, a $3,898 spread on the same certified stone. NZ Jewellers lists it at $7,883. 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.
