Rose Quartz Bracelet with Amethyst and Clear Quartz Faceted Beads
Amethyst is the purple variety of quartz and is one of the most popular gems. If it were not for its widespread availability, Amethyst would be very expensive. Amethyst is a widely used gem.
The name "amethyst" comes from the Greek word "amethustos" which means "not drunken."
In the first century, Pliny wrote that amethyst was so named for its color being nearly the same as that of wine. Early Greeks believed that drinking wine from an amethyst cup would prevent intoxication.
Amethyst and are both verities of Quartz. The difference is color. But natural, with its lovely transparent yellow to orange color, is extremely rare. So almost all on the market is actually amethyst that's been heated to change its color.
Amethyst may be used to remove radiation the body stores on the sides of the head...such as from computers and such. of Amethyst are particualy good for this, just place the head next to it, you will then feel the radiation being drawn out.
Place on the 3rd eye and visualize yourself breathing in the color for total mental emotional soothing. It's a very good technique to do in bed before going to sleep.
It is a amazing all round healer and also a brilliant meditation crystal.
Amethyst can be used for massage in, egg or form.
It makes a great elixir.
Rose Quartz is a form of that ranges in color from pink to deep red.
The pink can be almost rose red and some African verities border on lavender. The color seems to be caused by iron and titanium impurities. However the color of rose is still not completely understood. It has been said to be due to a number of different minor impurities present in the rose including titanium, manganese and even colloidal gold.
The pink color in Rose is photosensitive and can fade in sunlight.
Rose is almost always massive, rarely occurring in small horizontally striated hexagonal prisms. Brazil is the only source of true well formed of rose. Rose are thus extremely valuable.
Rose has been used as a gemstone and as other ornamental and religious objects for thousands of years. Historically, it is a symbol of love and beauty.
Facets are flat faces on geometric shapes. The organization of naturally occurring facets was key to early developments in crystallography, since they reflect the underlying symmetry of the crystal structure. Gemstones commonly have facets cut into them in order to improve their appearance.
Of the many hundreds of facet arrangements that have been used, the most famous is probably the round brilliant cut, used for diamond and many colored gemstones. This arrangement of 57 facets was calculated by Marcel Tolkowsky in 1919. Slight improvements have been made since then, including the addition of a 58th facet (a culet) on the bottom of the stone. Since this is calculated to show maximum brilliance, round diamonds are rarely cut in any other arrangement, although recently the Princess cut is becoming popular. Other cuts, including "rose" cuts, are most typically found in antique jewelry. See diamond cuts for an in-depth discussion and diagrams of various shapes and ways of cutting faceted stones.
The art of cutting a gem with facets is a very precise activity. The aim with a faceted cut is to produce an article that sparkles with internally reflected light, and that shows off the "fire" of the stone. Accordingly, only transparent or translucent stones are usually faceted.
The angles between each facet are precisely calculated. As the aim is to maximise the effect of the internal reflections, these angles depend on the refractive index of the material. This means that although the name and general shape of a particular cut may be the same between different materials, the actual angles will be slightly different, for the maximum effect.
Thus, although cubic zirconia and rock crystal may look similar to diamond, and all can be cut in a round brilliant cut, the angles must be different to produce the same optical effects. Additionally, as diamond has a refractive index significantly higher than the other natural transparent stones, it can have a much greater sparkle than other materials.
While some facets can be cut by cleavage, specialised machines are used for cutting arbitrary facets. These consist of two main features:
a flat abrasive, usually diamond dust of precise size bonded onto a metal disk (called 'laps') or carried by an oily fluid on a smooth metal or ceramic disk, and
a system for holding a stone onto the disk at a precise angle and position.
This usually requires the stone to be attached to a holder or dop, which is then placed in an indexed vice. This allows progressively finer abrasives to be used without disrupting the orientation of the stone. The final abrasive must be smaller than the wavelength of light, so that the scratches it creates are invisible. Modern machines tend to have indexed gears for moving the stone, so that rotating the stone to cut the next facet can be more precisely controlled.
An older machine called the jamb peg faceting machine used wooden dop sticks of precise length. By placing one end into one of many precisely located holes in the jamb peg, the other end, with the stone, could be precisely placed onto the lap. These machines took considerable skill to use effectively.
Much less commonly, faceters use cylindrical machines, which leave concave facets. This technique is most noticeably used around the gem's girdle.
