About this 0.31ct natural heart diamond

This 0.31ct natural heart sits in the sub-half-carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1555708400. Listed at 11 retailers as of November 4, 2026, with a 235% 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.
