Fracture filling is a very common with emeralds. The fracture is filled with
colourless oils or resins, this will improve the colour and clarity of the
Inclusions Emeralds have many natural inclusions. Only the very finest qualities are
transparent, as most emeralds are clouded by inclusions these can be liquid or
gas bubbles, healing cracks and foreign crystals. These inclusions are not necessary classed as
faults, but are evidence as to the genuineness of the gem.
Cleaning & Care Warm soapy water and a soft toothbrush will help maintain
the sparkle of your emerald. Estimates state that approx 90 % or more of
emeralds are fracture-filled. Since the great majority of fashioned natural
emeralds contain filled fractures, it’s risky to clean them ultrasonically or
with steam. Ultrasonic vibrations can weaken already-fractured stones. Heat can
damage emeralds, especially by extending existing fractures. Light and
chemicals can cause the oils, resins used to fill surface-reaching fractures to
alter in appearance or deteriorate. Visit us on a yearly basis for a FREE clean

in a cloth pouch or in a separate compartment to other gemstone jewellery (i.e,
diamonds are a higher hardness level on the Mohs scale) they could cause
scratches to other items of gemstone jewellery that have a lower hardness
