About this 1.42ct lab-grown round diamond

This 1.42ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799643978 or 799643978. Listed at 3 retailers as of October 25, 2026, with a relatively tight 1% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
