Emerald: Buying Guide

Emeralds are prized for colour over clarity — and almost all are treated with oil or resin.

Jardin and clarity

Inclusions in emerald are called 'jardin' (garden). Eye-visible inclusions are normal; what matters is colour, liveliness and stability.

Enhancement levels

Labs grade clarity enhancement as None, Minor, Moderate or Significant. Colombian emeralds with no or minor oil carry the highest premiums.

Care

Avoid ultrasonic cleaners and heat, which can remove oils.

Verification tools & references

Every Riakoob piece arrives certified, insured and covered by our 12-month value promise.
