About this 0.67ct natural heart diamond

This 0.67ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7511835923. Listed at 21 retailers as of October 30, 2026, with prices from $950 to $3,710, a $2,760 spread on the same certified stone. NZ Jewellers lists it at $3,710. 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.
