Touchstone offers some wonderful choices when it comes to opal and tourmaline jewelry for your October birthdays.

 Opals are translucent with flashes of color due to the amorphous non - crystalline order. It is like a liquid caught in a frozen state with particles floating around with no defined order so we call it a mineraloid and not a mineral.
Care: Opals are a delicate gemstone that need special care. Please do not  knock them as they can scratch easily. (Not recommended to wear while doing house work or gardening!)  Clean your opal jewelry with a mild soap and a very soft brush. 
Source: Opals are found in Australia, Brazil, Czech Republic, Ethiopia, Honduras, Indonesia, Mexico, Poland, Tanzania, and the United States.

Tourmaline is one of the most vivid of gemstones. IT comes in many combinations of color including "watermelon" tourmaline as shown in this pair of earrings and the necklace pictured.

The necklace has a full display of tourmaline in both rough gems and also natural forms of dark greenish black tourmaline crystals at each station. The center piece is a large watermelon tourmaline showpiece. Source: Tourmaline is found in Pakistan, Afghanistan, Myanmar, Australia, Canada, and the US. Tourmaline is also the gemstone for the state of Maine.

 Citrine is our colorful birthstone for the month of November. Citrine, not unlike Fall leaves is pale yellow to orange brown, to root beer like deeper hues. So lets cozy up to citrine with its warm earth tone colors to bring into our décor and fashion jewelry. To help you with finding the right piece of citrine Touchstone Gallery offers many choices in citrine in carved hearts, wonderful geode tables on hand crafted metal stands, geode butterfly wings, and faceted jewelry. 
Metaphysical properties: Abundance, prosperity, things that are related to the harvest this time of year.
About: Natural citrine is rare when found in nature. It is a type of crystalline quartz that may have started as amethyst. You may ask why would you turn amethyst to citrine? Well, like all things we like to have variety. So we take amethyst and heat treat it to change amethyst to citrine. It is still a natural mineral, just that we have speeded up the process by a few million of years of climactic forces on the mineral. 
Care: Since citrine is essentially quartz it is a hard mineral and makes wonderful faceted jewelry.  Clean your citrine jewelry with warm water, mild detergent and soft brush. 
Source: Brazil is the leading producers of citrine but can be found in other areas of the world like Bolivia; Democratic Republic of the Congo; Madagascar; Mexico; Myanmar; Namibia; Peru; Russia; South Africa; United States; Zambia.
