Cleaning & Care Warm soapy water and a soft toothbrush will help maintain
the sparkle of your Ruby. Ultrasonic and steam cleaners are usually safe for
untreated, heat-treated, and lattice diffusion treated stones. Fracture-filled,
cavity-filled, or dyed material should only be cleaned with a damp cloth.
Ruby is resistant to the effects
of heat, light, and common chemicals. Boric acid powder will etch the surface
of even untreated stones. Fracture-filled, cavity-filled, and dyed stones can
be damaged by even mild acids like lemon juice. Visit us on a yearly basis for

Storing Your Ruby When you are not wearing your Ruby jewellery place it 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 level.
Ruby has accumulated a host of legends over the centuries.

enabled their owners to live in peace with their enemies. In Sanskrit, ruby is
ratnaraj meaning king of gems. In Burma warriors wore rubies to make themselves
invincible during battle. Many medieval Europeans wore rubies to guarantee them
health, wealth, wisdom and success in love. The world's largest ruby is owned
by a Chinese jewellery company, It weighs 8184g (40920 Carat) and measures 5.11
