About this 0.53ct lab-grown heart diamond

This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818609103 or 818609103. Listed at 6 retailers as of November 4, 2026, with prices from $453 to $1,559, a $1,106 spread on the same certified stone. MOH London lists it at $1,559. 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.
