About this 0.9ct lab-grown heart diamond

This 0.9ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG639487413 or 639487413. Listed at 22 retailers as of October 27, 2026, with prices from $319 to $2,894, a $2,576 spread on the same certified stone. Queensmith lists it at $2,894. 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.
