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 VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6545425894. Listed at 16 retailers as of October 29, 2026, with a 131% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
