About this 0.73ct lab-grown heart diamond

This 0.73ct 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 LG726510422 or 726510422. Listed at 20 retailers as of October 30, 2026, with prices from $239 to $1,318, a $1,079 spread on the same certified stone. Reve Diamonds lists it at $1,318. 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.
