About this 1.02ct lab-grown oval diamond

This 1.02ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG819698106 or 819698106. Listed at 6 retailers as of November 6, 2026, with a relatively tight 24% spread, which is unusual at this carat range and suggests competitive pricing across the listings. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
