About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2567613673. Listed at 16 retailers as of October 30, 2026, with prices from $705 to $2,980, a $2,274 spread on the same certified stone. NZ Jewellers lists it at $2,980. 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.
