About this 0.51ct lab-grown radiant diamond

This 0.51ct lab-grown radiant 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 LG782612205 or 782612205. Listed at 18 retailers as of October 26, 2026, with prices from $207 to $1,213, a $1,007 spread on the same certified stone. MOH London lists it at $1,213. 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.
