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 LG818608856 or 818608856. Listed at 7 retailers as of October 29, 2026, with prices from $320 to $1,110, a $790 spread on the same certified stone. MOH London lists it at $1,110. 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.
