About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG790611909 or 790611909. Listed at 18 retailers as of October 29, 2026, with prices from $215 to $1,243, a $1,028 spread on the same certified stone. Reve Diamonds lists it at $1,243. 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.
