About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1509375272. Listed at 6 retailers as of November 1, 2026, with prices from $2,906 to $4,691, a $1,785 spread on the same certified stone. 77 Diamonds lists it at $4,691. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
