Quartz is one of the most important minerals on earth and makes up one of the
most popular gemstone groups in the world of colored stones. It is the second
most abundant mineral found in Earth's continental crust, second only to the
feldspars. The name 'quartz' is thought to be derived from the German word
'quarz', which likely originated from the Slavic and Polish words meaning
'hard'.
Pearls are organic gemstones that are formed by shelled molluscs; mainly bivalved oysters and mussels. Pearls are made up of nacre (mother-pearl) which is mostly aragonite (calcium carbonate) and conchiolin. The aragonite microcrystals build up around an irritant. The name "pearl" is said to have originated from the Middle English word "perle", which in turn came from the Latin word "perna", meaning "leg", thought to be due to the ham-leg shape of the bivalve mollusc.
