About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1558818360. Listed at 11 retailers as of November 4, 2026, with a 69% 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.
