About this 0.55ct natural marquise diamond

This 0.55ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 706509323. Listed at 6 retailers as of November 4, 2026, with prices from $931 to $1,525, a $594 spread on the same certified stone. MOH London lists it at $1,525. 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.
