About this 0.51ct natural pear diamond

This 0.51ct natural pear sits in the half to three-quarter carat band, graded I colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2507605388. Listed at 7 retailers as of October 31, 2026, with a 51% 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.
