About this 1.23ct natural emerald diamond

This 1.23ct natural emerald sits in the classic one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6542578608. Listed at 2 retailers as of November 4, 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.
