The ELEGANCE COLLECTION - A Graceful Classic Design !

SOLD With a center highlight faceted gemstone of Lepodolite, white potatoe freshwater cultured Pearls, amethyst and light amethyst Swarovski Crystals, this 21 inch necklace presents a graceful and classic look.
The necklace is finished with a silver platted patterned square Toggle Clasp.

The earrings are Sterling Silver circular Shepards Crooks with a 1 1/2 inch pearl and crystal oval dangle.


Lepodolite is a lilac-gray or rose-colored phyllosilicate mineral in the mica group that is a secondary source of lithium. It is associated with other lithium-bearing minerals like Spodumene in pegmatite bodies. It is one of the major sources of the rare alkali metals rubidium and caesium. It occurs in granite pegmatites, in some high-temperature quartz veins, greisens and granites. Notable occurrences include Brazil, Russia, United States,Canada and Madagascar.


Freshwater Cultured Pearls are a kind of pearl that comes from freshwater mussels. They are produced in Japan and the United States on a limited scale, but are now almost exclusive to China. The U.S. Federal Trade Commission requires that freshwater pearls be referred to as "freshwater cultured pearls" in commerce. Although the Japanese freshwater pearl industry has nearly ceased to exist, it holds special historic value as the first country to cultivate whole freshwater pearls in Lake Biwa, using the Biwa pearly mussel. The industry attempted a comeback with a mussel hybrid in Lake Kasumigaura in the last decade, but this venture also met with failure, with production ceasing in 2006. The pearl farm in Tennessee also holds special historic value as it is the only freshwater pearl outside of Asia, it continues as a tourist attraction. Today China is the only commercial producer of freshwater pearls, producing 1500 tons using a triangle shell mussel and several hybrids that have shown heterosis from several mussel species.


Swarovski Crystals are also used in this set.

Purple Gemstones !

When one talks about gemstones and the color purple is mentioned, normally the conversation then tends towards the well known and very popular purple February Birthstone gemstone called Amethyst. Some will also think of the gemstone Ametrine, which is a unique dual gemstone of Amethyst and Citrine.




But there are some other purple colored gemstones that can also be used to make some very colorful and unique jewelry pieces. Four additional purple colored gemstones that are used quite often in jewelry are listed below.

It occurs in granite pegmatites, in some high-temperature quartz veins, greisens and granites. Notable occurrences include Brazil, Russia, United States,Canada and Madagascar.



Sugilite (also known as Luvulite) is a relatively rare pink to purple cyclosilicate mineral. Sugilite crystallizes in the hexagonal system with prismatic crystals. The crystals are rarely found and the form is usually massive. It is mostly translucent but can be opague when mixed with a host rock. Sugilite was first described in 1944 for an occurrence on Iwagi Islet, Japan, where it is found in an aegirine syenite intrusive rock. It is found in a similar environment at Mont Saint-Hilaire, Quebec, Canada. In the Wessels mine in northern South Africa, Sugilite is mined from a strata-bound manganese deposit. It is also reported being found in Italy, Australia and India.


Sodalite is a light, relatively hard yet fragile mineral named after its sodium content; in mineralogy it may be classed as a feldspathoid. Well known for its blue color, Sodalite may also be grey, yellow, green, or purple and is often mottled with white veins or patches. The more uniformly blue material is used in jewelry but the fashionable purple variety hold the greatest attention. It is normally fashioned into cabochons for pendants and beads. Lesser grade material is more often seen as facing or inlay in various applications. Although somewhat similar to Lazurite and Lapis Lazuli, Sodalite rarely contains Pyrite and its blue-purple color is more like traditional royal blue than ultramarine. It is further distinguished from similar minerals by its white (rather than blue) streaks. Sodalite's six directions of poor cleavage may be seen as incipient cracks running through the stone.




And last but not least we have to consider our tried and true gemstones made out of Agate. In one specific location in the Campo Morado area of Mexico, south-southwest of Mexico City, there is a very purple colored Agate. It is a naturally colored purple Agate called the Morado Agate. But as with many other Agates and Jaspers, buyer beware because many are dyed and purple is one of the favorite colors.

Jewelry Set - Summertime Lavendar Colors !

In keeping with the delicate Summertime theme, lavendar is a perfect color.

.
SOLD

This lavendar colored presentation created by Gayle is highlighted by a marquise shaped Sugalite pendant with Freshwater Pearl clusters on either side and complimented with additional Pearls, Amethyst, Lepodolite and Fluorite beads. The necklace is then completed using a Silver S-hook Clasp. Matching dangle French Hook Earrings containing the same gemstone beads completes the set.

.

Sugalite (also spelled "sugilite") is a semi-precious stone that was discovered in 1944. It is named after Ken-ichi Sugi, a Japanese geologist who originally discovered the stone. Sugalite typically has a lavender or purple color--it can range from dark purple to pale lavender with hints of gray. Opacity varies significantly across sugilite grades. Matrixing and opaque blotches are common. Translucent specimens with little matrixing are far more valuable than opaque sugalite stones. Sugalite specimens are typically scored between 6 and 7.5 on the Mohs harness scale. The hardness of sugalite is comparable to that of quartz crystal, making it durable enough to use in gemstone jewelry such as pendants, bracelets and earrings. Occcurances of gem quality Sugalite can be found in Japan, Canada, South Africa, Italy, Australia and India.

.

Lepodolite (also spelled Lepidolite) is an uncommon mica and has only in the past decade become available on the mineral market in large quantities in gemstone quality. Lepidolite is an ore of lithium and forms in granitic masses that contain a substantial amount of lithium. The lithium content in lepidolite does vary greatly however and low lithium lepidolite is nearly useless as an ore of lithium. The typical violet to pink color of lepidolite is characteristic and is the only field test available to identify lepidolite from other micas. Pink muscovite or very pale lepidolite may confuse an identification. Lepidolite, like other micas, has a layered structure of lithium aluminum silicate sheets weakly bonded together by layers of potassium ions. These potassium ion layers produce the perfect cleavage. lepidolite crystals accompany such other lithium bearing minerals such as tourmaline, amblygonite and spodumene and can add greatly to the value of these specimens. A rock made of granular pink lepidolite and red to pink tourmaline is used as an ornamental stone for carving and in jewelry such as pendants and earrings. Single large plates or "books" of lepidolite can have appealling violet color and make attractive specimens. Notable occurrences include Brazil, Russia, Calafornia, Canada and Madagascar.

.

Fluorite (also called "fluorspar") is a halide mineral composed of calcium fluoride. It is an isometric mineral with a cubic habit, though octahedral and more complex isometric forms are not uncommon. Crystal twinning is common and adds complexity to the observed crystal habits thus making it great for jewelry. Fluorite comes in all colors of the rainbow, but purples and greens are most common. Fluorite is a widely occurring mineral which is found in large deposits in many areas. Notable deposits occur in China, Germany, Austria, England, Norway, Mexico, Canada, Kenya and many States in the United States. Fluorite has been the state mineral of Illinois since 1965. At that time, Illinois was the largest producer of fluorite in the United States, but the last fluorite mine in Illinois was closed in 1995.

.

Amethyst is the purple variety of quartz and is a popular gemstone. If it were not for its widespread availability, amethyst would be very expensive. The name "amethyst" comes from the Greek and means "not drunken." This was maybe due to a belief that amethyst would ward off the effects of alcohol, but most likely the Greeks were referring to the almost wine-like color of some stones that they may have encountered. Its color is unparalleled, and even other, more expensive purple gemstones are often compared to its color and beauty. Although it must always be purple to be amethyst, it can and does have a wide range of purple shades. Amethyst can occur as long prismatic crystals that have a six sided pyramid at either end or can form as druzes that are crystalline crusts that only show the pointed terminations. As a mineral specimen, amethyst is popular for its color and nice crystal shapes that produce a handsome, purple, sparkling cluster. However, amethyst is not the same everywhere. Different localities can produce a unique amethyst to that particular region or even to that particular mine. Experts can often identify the source mine that a particular amethyst came from. The key to this is the specimen's color, shape of crystal, inclusions, associations and character of formation.

Freshwater Pearls and Crystals are the other items in this jewelry piece.

THE COLOR PURPLE !

Lepodolite Jasper & Amethyst

PURPLE is the new black ! Well, not quite. Will anything ever be the new black? But purple is this season's welcome addition to our beloved black. Be it grape or lilac, lavender or wine, violet, plum, puce, mauve, magenta, amethyst, pomegranate, eggplant or mulberry, there's no question that purple is the color of this fall and winter season. After all, we need something that is rich, luscious and exotic to liven up what has become an all-too-serious season of stripped-down, black-and-charcoal basics and bad financial times. Purple can bounce off of black, be used as a layering piece, or a shawl.
.
Indeed, not since the recessionary 1980s have we seen so much of the royal hue in our clothing, jewelry, accessories and even makeup. We're seeing other '80s-era jewel tones, too - fuchsia, teal and power red - but it's purple that's popping up most often on everyone from TV pundits to yoga teachers to bank tellers to stars striding along the red carpet. Purple, a perfect blend of hot red and cool blue, is that rare color that's flattering on everybody. Some hues are better on some people than others, of course - deep, royal purple looks great on people with dark, dramatic colouring, for instance, while warm, wine-y shades are terrific with golden skin tones and cool lavender is lovely on fair beauties. Purple is also one color whose mood changes depending on what it is paired with. It is a chameleon, becoming earthy when matched with browns and beiges, delicately feminine with pinks and other pastels, dramatically eccentric with brights like red or green, and seriously sophisticated with silver, charcoal, black and other cool neutrals. In fact, very dark and very light purples practically are neutrals, just a whisper away from black, navy or dove grey. Symbolically, purple has long had a wide range of meanings including nobility, regality, ritual, imagination, spirituality and creativity.
.
That's one of the reasons the color experts have chosen a shade of purple, "Blue Iris", as 2008's color of the year: "Combining the stable and calming aspects of blue with the mystical and spiritual qualities of purple, Blue Iris satisfies the need for reassurance in a complex world, while adding a hint of mystery and excitement." Long ago, purple was one of the most expensive, most difficult dyes to create, and so it was reserved for royalty. In coats of arms, it is still used to represent the gentry, and in military terms is awarded to the bravest, most noble of soldiers. It has also been a significant color for the ecclesiastical set, most notably for Roman Catholic bishops' robes, and has long been associated with spirituality, mysticism and the unknown. In many cultures, purple is also a color of mourning. Thai widows, for instance, traditionally wear purple, and during the Victorian era, purple was the transitional color for women in the period between deep mourning and the return to regular society.

Turquoise & Amethyst

More happily, though, it is also considered a creative color, the color of imagination, artistry, free-thinking and sensitivity. Many fashion experts believe that colors become popular not just because they are new and fresh and we're bored with last year's trendy shades, but because they resonate with the ethos of the times. So why purple, why now? Perhaps it is because, after a period of rampant excess and crass consumerism, we yearn to tap into our nobler selves, to seek a higher spirituality, to mourn the lost dreams of the North American middle class and to reconnect with our creative side. Or perhaps it's simply because it is beautiful, and it makes us feel beautiful when we wear it. And how you choose to wear purple is up to you - there is really no wrong or right way. You can keep it subtle, simply adding a touch of black currant eye shadow or the sparkle of an amethyst-coloured necklace to a black or grey outfit. Or you can add a bigger punch of drama with a magenta handbag, plum-coloured pump or a violet blouse or eggplant sweater under a businesslike jacket. Or you can go all out with high-impact pieces, like a purple party frock or mulberry puffer jacket.
.
But whether you go for subtle or spectacular, one thing for sure: it's a PURPLE reign this fall.
