About this 0.84ct lab-grown marquise diamond

This 0.84ct lab-grown 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 and certified by IGI LG823670225 or 823670225. Listed at 4 retailers as of November 2, 2026, with prices from $1,010 to $1,430, a $420 spread on the same certified stone. Kay Jewelers lists it at $1,430. 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.
