Boulder Opal
Boulder Opal

Boulder Opal is unique among gemstones with its intense flashes of color formed over 100 million years ago from hydrated silica embedded in ironstone. Opal comes from the Greek word 'opallus' which loosely translates as 'changing color'. Australia is the world's only source for boulder opals, with boulder opals making up only 2% of its entire opal output. As each opal is unique in color and shape boulder opals are usually cut flat or in cabochon with the natural ironstone backing intact.

A stone of strength, boulder opal is said to calm the inner soul, give clarity and aid in circulation.

Emerald
Emerald

The word emerald comes from the Greek 'smaragdos' meaning green stone. It is the most precious stone in the beryl group and in the precious top four of gemstones including sapphire, ruby and diamond. Emerald is highly valued for its deep bright green color. Inclusions are tolerated more in emeralds than virtually any other gem as they are considered part of the character of the natural stone.

Emerald was the sacred stone of the goddess Venus representing love, hope and healing.

Rhodochrosite
Rhodochrosite

Rhodochrosite is a rose-colored gemstone that was only introduced to the market around 1940. It can be recognized by its alternating raspberry red and pink stripes, somewhat similar in that respect to malachite or agate. The most common colors are light red and pink and it displays a vitreous luster when polished.  Transparent red crystals are rare and rhodochrosite is usually found in an aggregate form.

Due to its composition, rhodochrosite is also referred to as manganesespar or as raspberryspar with reference to its color. The name rhodochrosite comes from the Greek word, "rhodokhros", meaning "rose colored". In Argentina, rhodochrosite stalagmites formed in Inca silver mines that were abandoned centuries ago. Sometimes it is also called "Rosa del Inca" or "Inca rose stone" and it is said that the Incas believed that rhodochrosite was the blood of their former rulers that had turned to stone. Rhodochrosite is the national gemstone of Argentina and the state mineral of Colorado as significant deposits were discovered in both places. The main rhodochrosite deposits are in Argentina as well as Chile, Mexico, Peru, South Africa, Hungary and the USA.

Rhodochrosite's pink color associates it with emotional healing, love, compassion, creativity and intuition. Rhodochrolite is thought to encourage positive feelings, personal strength and to soothe its wearer. Physically, rhodochrolite is said to help blood pressure, respiration, migraines and in traditional Hindu beliefs, rhodochrolite is associated with Anahata, or the heart chakra, which is related to peace, decision-making, love, compassion and psychic healing.

Tourmaline
Tourmaline

Tourmaline is the gemological name for an important group of complex gem-quality boron silicate minerals. Its name is thought to be derived from the Sinhalese word 'turamali' or 'stone with mixed colors' as tourmaline can be found in all colors of the rainbow from brown, yellow, pinks to blues. Most red, pink and brown to yellow tourmaline is colored by manganese, while iron and titanium can result in greenish to bluish-black colors. The rare emerald-green tourmaline is colored by chromium (and sometimes vanadium).

Tourmaline has been known since antiquity in the Mediterranean region with the Dutch importing it in 1703 from Sri Lanka to Western and Central Europe. Tourmaline is also the national gemstone for the United States, where it has been mined for centuries. Tourmaline is said to be a powerful detoxification stone that invites positive energy.

Ametrine
Ametrine

Ametrine is a quartz gemstone that combines Amethyst and Citrine to create a unique purple yellow hue. The only difference between amethyst, citrine and ametrine is the level of iron in the visible color-zone bands. Although Ametrine has been used since the 17th century, introduced to Europe by the Spanish conquistadors, it was not commercially mined until the 1980s. Ametrine is found in only one mine in the world, in Bolivia.

Since Ametrine is the union of both Amethyst and Citrine, Ametrine combines the powers of both: Amethyst for sobriety and Citrine for prosperity and protection against evil thoughts.

Carnelian

Carnelian is a member of the chalcedony quartz family and is identified by its distinct orange to reddish color with a translucent to opaque wax-like luster when cut and polised.  This color occurs through the prescence of iron impurities in the quartz.

Carnelian is thought to bring good luck to the wearer and protect against poverty and bad energy.

Fire Opal

Ruby

The most important sources for ruby include Burma, Thailand, Sri Lanka and Tanzania. In 2000, new Ruby sources were discovered in Madagascar (in Vatomandry and Andilamena). These deposits turned out to be very extensive and productive, and Madagascar is now one of the leaders in Ruby output.

Legend states that he owner of a ruby is assured a life of peace and plenty. Ruby has long been attributed with the ability to protect its wearer from injury and to cure blood disorders. It is also said to provide its wearer with energy, emotional strength, positive attitude, heightened awareness and focus.

This chakra is concerned with Kundalini; spiritual energy, the power of pure desire, divine consciousness, opening of the mind and natural energy of the self.

 

Tsavorite
Tsavorite

Tsavorite, discovered in the late 1960s in Tsavo, Kenya, is a form of Grossular garnet and is often mistaken for Emerald due to its deep green color that comes from exposure to chromium and vanadium deep within the earth. In fact, it is clearer, more brilliant and more durable than Emerald. Larger Tsavorite specimens are almost non-existent which is why we usually only see Tsavorite in smaller sizes.

Tsavorite is a rare stone and today only has 4 small mines in production in Africa. Tsavorite garnet is thought to provide its wearer with strength, vitality and positivity.

Sapphire
Sapphire

The name Sapphire derives from Greek 'sappheiros' meaning blue, yet sapphires come in a wide array of colors including pink, yellow, orange and green. Sapphire is a gem quality variety of the mineral corundum - aluminum oxide which crystallized into gemstones with the presence of small amounts of other elements, especially iron and chrome that are responsible for the color. A ruby-red sapphire colored by chrome is actually a Ruby. Sapphires are the second hardest substance on earth after diamond. In times of antiquity and the Middle Ages, the term sapphire actually referred to lapis lazuli but in the early 19th century, the description and definition of sapphire was changed to what we know today.

Throughout history Sapphire has symbolized truth, loyalty and protection.

Turquoise
Turquoise

The word Turquoise comes from the French word "Turquie" (named after the country Turkey) as trading routes brought Turquoise from Persia through the Middle East towards Europe in the 17th century.  Turquoise can come in different shades of blue or green, and is commonly veined or mottled with brown or black oxides or a sandstone base. Some prefer color veining while others prefer a solid-colored deep turquoise-blue hue.

The turquoise that is found in the USA contains iron rather than aluminum, so it is actually a mixture of turquoise and chalcosiderite. Since it contains iron, it is a green color. Pure blue turquoise is rare and turquoise is mostly interspersed by brown, dark-gray or black veins, which can be sparse or dense. These veins are either the host rock or other minerals and turquoise that contains veins is referred to as "turquoise matrix". Turquoise is mined chiefly in Iran, Afghanistan, China, Australia, Chile, Mexico, and in Arizona and Nevada inthe US.

Turquoise has a long history of use as a talisman or amulet. The ancient Egyptians believed that the color blue was a symbol of regeneration, so turquoise was treasured for both decorative and superstitious purposes. Turquoise was also used by Native Americans in works of art and jewelry, some of whom believed that it possessed protective properties. The Tibetans believe in the healing properties of turquoise and have valued turquoise jewelry for centuries.

While emerald is colored by trace amounts of chromium (and vanadium), aquamarine color is the result of iron impurities within colorless beryl crystal.

Diamond Slices are sliced diamond sections prized for their unique inclusions and pattern definition with varying hues and colors that are completely different from traditional faceted diamonds. Three-rayed 'trapiche' diamond slices are amongst the most scarce and striking of these as they contain a recognizable radiation-symbol pattern.
