About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG811641426 or 811641426. Listed at 19 retailers as of November 2, 2026, with prices from ₹11,243 to ₹1,16,390, a ₹1,05,147 spread on the same certified stone. MOH London lists it at ₹1,16,390. 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.
