SEPTEMBER - SAPPHIRE

The only difference between a Ruby and a Sapphire is simply the colour. The colour of a Sapphire is created by various amounts of iron and titanium in the stone, the combination of which produce varying colours. Whilst the most desirable colour Sapphire is blue, ( specifically a“cornflower blue’) they also come in violet, dark gray, orange, yellow, pink, green and black. These different coloured Sapphires are referred to as “fancy Sapphires” and are often less expensive than the blue ones, yet equally as beautiful, and a fine alternative to blue. 
A rare orange - pink coloured kind of Sapphire is called “Padparadscha,” which means “Lotus Flower” in Sinhalese, is very expensive and is the only colour Sapphire given its own name. Because Sapphires are available in so many colours, they are an incredibly versatile gemstone.

OCTOBER - TWICE AS NICE

OCTOBER - TWICE AS NICE

Through the ages referred to as, ‘The tears of Zeus”, and believed by the Bedouins to be filled with Lightning, the kaleidoscopic play of colour trapped within Opals has made them a source of fascination for centuries.

Most modern references suggest it is adapted from the Sanskrit word "Upala” which literally translates to the word “jewel”. The argument for the Sanskrit origin is strong. The term first appears in Roman references around 250 BC, at a time when the opal was valued above all other gems. The word itself has two meanings, one is related to "seeing" and forms the basis of the English words like "opaque"; the other is "other" as in "alias" and "alter". It is claimed that opalus combined these uses, meaning "to see a change in colour".
