Emerald – May Birthstone

Emeralds are fascinating gemstones. They have the most beautiful, most intense and most radiant green that can possibly be imagined: emerald green. Inclusions are tolerated. In top quality, fine emeralds are even more valuable than diamonds. The name emerald comes from the Greek ‘smaragdos’ via the Old French ‘esmeralde’, and really just means ‘green gemstone’. Innumerable fantastic stories have grown up around this magnificent gem. The Incas and Aztecs of South America, where the best emeralds are still found today, regarded the emerald as a holy gemstone. However, probably the oldest known finds were once made near the Red Sea in Egypt. Having said that, these gemstone mines, already exploited by Egyptian pharaohs between 3000 and 1500 B.C. emerald-in-rectangular-cut

Palladium is a platinum group metal that acts a lot like platinum itself, but is lighter in weight and less expensive. It is hypo allergenic, sturdy, long wearing and naturally very white. It was used extensively during World War Two, when Platinum was scarce, but jewellers kind of forgot about it. It offers an excellent choice for jewellery as it’s workable and beautiful.

It does not require rhodium plating like white gold jewellery.

Diamond – April birthstone

Diamond :from the ancient Greek  adámas “unbreakable”) Diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools. Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers  in the Earth’s mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth). Diamonds are brought close to the Earth’s surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlite. .diamond-find-rough

Aquamarine – March birthstone

Iron is the substance which gives aquamarine its colour, a colour which ranges from an almost indiscernible pale blue to a strong sea-blue. The more intense the colour of an aquamarine, the more value is put on it. Some aquamarines have a light, greenish shimmer; that too is a typical feature. However, it is a pure, clear blue that continues to epitomise the aquamarine, because it brings out so well the immaculate transparency and magnificent shine of this gemstone.
