How much do you know about Amethyst?

April 23rd, 2010 900jewelry 3 comments

Amethyst is a violet variety of  quartz often used in jewelry. The name comes from the Ancient Greek ,a reference to the belief that the stone protected its owner from drunkenness; the ancient Greeks and Romans wore amethyst and made drinking vessels of it in the belief that it would prevent intoxication .

In the 20th century, the color of amethyst was attributed to the presence of manganese. However, since it is capable of being greatly altered and even discharged by heat, the color was believed by some authorities to be from an organic source. Ferric thiocyanatewas suggested, and sulfur was said to have been detected in the mineral.

More recent work has shown that amethyst’s coloration is due to ferric iron impurities.Further study has shown a complex interplay of ironand aluminium is responsible for the color.

On exposure to heat, amethyst generally becomes yellow, and much of the citrine, cairngorm, or yellow quartz of jewelry is said to be merely “burnt amethyst”. Veins of amethystine quartz are apt to lose their color on the exposed outcrop.

About Coral

November 6th, 2009 900jewelry No comments

Coral is not a mineral but a hard calcareous substance consisting of the continuous skeleton secreted by many tribes of marine coelenterate polyps for their support and habitation. It is found growing plant-like on the sea-bottom. With pollution on the rise everywhere it is becoming increasingly rare, to the extent that even the most prized, the Mediterranean coral, is threatened with extinction.

Coral was very popular until a few years ago, but has now become too expensive for most pockets. Its increasing rarity does. however, make it a good long-term investment. You would be wise to buy Italian coral rather than specimens from the Far East, which have often been adulterated.

The best corals are generally considered to be those of a deep rose red colour, though some jewelers would tend to disagree. Understandably so, when it is almost impossible to find more than one or two necklaces of this shade in a hundred ! As regards white and pink varieties, choose without hesitation the colour known as “angel’s skin”.

Weight-wise, coral is worth more on today’s market than gold, which is why it is such a sound investment provided, and I stress this, it is of the best quality. The finest specimens come from Sardinia and Tunisia; larger, less fine ones from Japan and China.

Coral is cut en cabochon or used for beads and sometimes small carvings. Beware of imitations, such as coloured shell or bone.

Agate is a variety of  chalcedony formed from layers of quartz which usually show varicolored bands. It usually occurs as rounded nodules or veins.

Often tiny quartz crystals form within the stone and add to the beauty and uniqueness of individual stones. These crystals are called druzy(sometimes misspelled as druzy). Lapidaries often cut just the drusy from an agate and jewelers use these drusy cabochons as the main stone or as an accent stone in their jewelry designs.

Some named varieties are: moss agate, eye agate; and plume agate, which looks like it’s filled with beautiful feather plumes .

Agate is a relatively inexpensive stone except for some varieties with unusual banded or scenic markings.
