About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded D colour (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 2506491777. Listed at 16 retailers as of October 30, 2026, with prices from $4,197 to $9,405, a $5,208 spread on the same certified stone. NZ Jewellers lists it at $9,405. 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.
