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 15 retailers as of November 2, 2026, with prices from $5,986 to $13,420, a $7,434 spread on the same certified stone. NZ Jewellers lists it at $13,420. 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.
