About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG836617387 or 836617387. Listed at 12 retailers as of October 29, 2026, with prices from $248 to $2,312, a $2,064 spread on the same certified stone. MOH London lists it at $2,312. 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.
