About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-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 6541025827. Listed at 20 retailers as of October 30, 2026, with prices from $1,682 to $4,605, a $2,923 spread on the same certified stone. NZ Jewellers lists it at $4,605. 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.
