About this 0.91ct natural heart diamond

This 0.91ct 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 1545945750. Listed at 5 retailers as of October 31, 2026, with prices from $2,531 to $3,018, a $487 spread on the same certified stone. Blue Nile lists it at $3,018. 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.
