About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG791649754 or 791649754. Listed at 12 retailers as of November 3, 2026. 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.
