About this 1.15ct lab-grown round diamond

This 1.15ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade and certified by IGI LG490191094 or 490191094. Listed at 7 retailers as of October 23, 2026, with a relatively tight 10% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
