This 0.9ct lab-grown round sits in the just-under-one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG805672195 or 805672195. Listed at 3 retailers as of November 2, 2026, with a relatively tight 8% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
