    Yes, Effy emeralds are generally real. However, not all pieces feature natural emeralds. The luxury jewelry maker uses a mix of naturally derived and lab-created gemstones in its jewelry.

However, fashion jewelry that features lab-grown or cultured gemstones other than diamonds can be found on the site.
