About this 0.86ct lab-grown heart diamond

This 0.86ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG844618747 or 844618747. Listed at 17 retailers as of October 31, 2026, with prices from $917 to $4,150, a $3,233 spread on the same certified stone. Riddles Jewelry lists it at $4,150. 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.
