Emerald
The green against which every other green is measured — and the one major gemstone where visible inclusions are accepted as part of its character.
About Emerald
Emerald is beryl colored by chromium and vanadium. It grows in a geologically violent environment, and the result is that nearly every emerald contains inclusions and fractures. The trade calls this the jardin, the garden, and a clean emerald is so unusual that it invites suspicion rather than admiration.
Because of that fracturing, the overwhelming majority of emeralds are treated with oil or resin to fill surface-reaching fractures and improve apparent clarity. The treatment is accepted but is not permanent, and an oiled emerald may need re-treatment over its life. The extent of the filling — none, minor, moderate, significant — materially affects value and should be documented.
Colombian material sets the standard for pure, slightly bluish green. Zambian emerald tends slightly darker and bluer and is often cleaner. At 7.5 to 8 on the Mohs scale emerald is reasonably hard but its fractures make it fragile in practice, which is why it needs a protective setting.
Why Sharon works with emerald
Sharon uses emerald sparingly and honestly, and she will often point a client toward fine green tourmaline or tsavorite garnet instead — comparable color, better clarity, far better durability, and a fraction of the price. When only emerald will do, she sets it protected.
Caring for emerald
Never use ultrasonic or steam cleaning on emerald — it can strip the oil and open fractures. Clean with a soft cloth and lukewarm water only, and avoid solvents and household chemicals.
Common questions about emerald
Why do emeralds have so many inclusions?
Because of the geological conditions in which they form. Inclusions are so universal that the trade regards them as characteristic rather than as a flaw, and a completely clean emerald is rare enough to warrant testing.
Are emeralds oiled?
The great majority are treated with oil or resin to fill surface-reaching fractures. This is accepted practice but is not permanent, and the degree of treatment should be stated on any report.
Is emerald suitable for an engagement ring?
It can be, in a protective setting and with realistic expectations about care. Sharon is candid that green tourmaline or tsavorite garnet will survive daily wear considerably better.
