About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 25 retailers as of November 4, 2026, with a 62% 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.
