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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1433343777. Listed at 10 retailers as of October 29, 2026, with a 111% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
