About this 0.54ct lab-grown round diamond

This 0.54ct 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 LG816603140 or 816603140. Listed at 18 retailers as of November 1, 2026, with prices from $122 to $1,363, a $1,241 spread on the same certified stone. MOH London lists it at $1,363. 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.
