ROCK TRIVIA: TOURMALINE ( stone of October )
Tourmaline has a variety of colors.from blues and greens, to reds, yellows and pinks.Gem and specimen tourmaline is mined chiefly in Brazil and Africa. 
Almost every color of tourmaline is found in Brazil, including a new blue and green variety that was found in the state of Paraíba. Another recent discovery in Mozambique has colors a bit less bright than the Brazilian, but it tends to be clearer and larger than that found in Brazil. 
Some fine gem quality material has been produced in the United States, During the early 1900s, Maine and California were the world's largest producers of gem tourmalines. Typically the colors are raspberry reds and bright pinks and mid-range greens as well as some bicolor in California.
Chrome tourmaline, found in Tanzania. is a rich green color due to the presence of chromium which also produces the green of emeralds.
Top quality indicolite (blue )and verdelite (green) are found in Afghanistan.These tourmalines have beautiful clarity and very intense color.

ROCK TRIVIA; MOONSTONE
The shimmer of light of the moonstone is something very special in the gemstone world. The inner construction of the gemstone causes light rays to be refracted and scattered in the stone. This very unique light effect is known as 'adularisation'. 
The classic moonstone, which is almost transparent with a bluish shimmer, come from Sri Lanka. However, they are also found in the USA, Brazil, Australia, Myanmar and Madagascar. For a few years, there have also been some green, brown and orange specimens on the market, as well as some with smoky and champagne colors, mainly originating from India.
Prices for Moonstone have the most astonishing range. The more intense in color, the larger and the more transparent, the more highly valued the moonstone. Bluish moonstones of good quality have been becoming more and more of a rarity in recent years and the prices for these will continue to rise exponentially.

ETHIOPIAN OPAL
Ethiopian Opal has the same molecular structure as Austrailian Opal. They are basically hydrated forms of Silica in a a unique formation. This formation does not crystallise in a regular form, and is called amorphous.
The main difference in Australian and Welo Opal is how much water they contain. Australian Opal is found deeper, so it has more pressure exerted on it and contains more water. Australian Opal is usually about 6% to 10% water and Welo Opal is closer to 3% to 5% water. Australian Opal has a tendency to dry out but Welo Opal can actually absorb more water.

JEWELRY BY TIME PERIODS; EDWARDIAN 1901-1915
The fashion was inspired by 18th century French courts and the look was light and delicate. Stars, ribbons and bows were favorite motifs for this period. Pastels, white-on-white, lace, Diamonds, Pearls and Platinum ruled the look.
The look of jewelry that looked like embroidery and lace was made possible by advances in platinum fabrication. Pale colored stones such as amethysts, aquamarines, peridots, pale green garnets and blue sapphires were also popular as well as black opals from Australia.
Pictured is an Edwardian diamond with Pearls and Sapphires and set in Platinum. A perfect example of the period as well as the Stone of September!
