About this 0.8ct natural marquise diamond

This 0.8ct 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 2566753263. Listed at 12 retailers as of October 31, 2026, with prices from $4,485 to $8,530, a $4,045 spread on the same certified stone. Helzberg Diamonds lists it at $8,530. 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.
