About this 0.74ct lab-grown heart diamond

This 0.74ct 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 LG734515310 or 734515310. Listed at 8 retailers as of November 1, 2026, with prices from $498 to $1,210, a $712 spread on the same certified stone. MOH London lists it at $1,210. 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.
