About this 0.53ct lab-grown heart diamond

This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG689506109 or 689506109. Listed at 9 retailers as of November 2, 2026, with prices from $325 to $1,137, a $812 spread on the same certified stone. MOH London lists it at $1,137. 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.
