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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2517450428. Listed at 11 retailers as of November 5, 2026, with prices from $758 to $2,577, a $1,819 spread on the same certified stone. NZ Jewellers lists it at $2,577. 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.
