The most significant difference between a Swiss and a Japanese replica watch is the movement, while Swiss replicas come with an ETA movement the Japanese replicas come with a Miyota movement, similar to the movement found on Citizen and Seiko watches.
Swiss replica watches's price usually range from $400 to $600
Mens Japanese watches's price range between $180 to $300 depending on the functions they have. Ladies Japanese watches usually sell for $100 to $200.
Glass is typically made by melting sand, Much of that sand consists of quartz. Some glass will also be made of recycled glass.
Quartz comes in every color imaginable, but the most popular purple gemstone bead I think would be amethyst. Some quartz is even dyed. the most common quartz colors I have seen are clear, white, rose, yellow, and smoky. the smoky and rose quartz being my favorite. If you have purple gemstone beads and don't know what it is, it could be quartz but most likely amethyst
Quartz is considered a gemstone due to several properties that make it desirable for use in jewelry and decorative objects. Here are some of the key properties of quartz that contribute to its status as a gemstone: Hardness: Quartz has a hardness of 7 on the Mohs scale, which measures a mineral's resistance to scratching. This level of hardness makes quartz relatively durable and less prone to scratches, making it suitable for use in jewelry. Clarity and Transparency: Quartz can occur in a wide range of transparency levels, from transparent to translucent. Clear, transparent quartz, known as rock crystal, is highly valued for its clarity and ability to refract light. This property allows quartz gemstones to exhibit brilliance and sparkle. Color Varieties: While quartz is commonly associated with clear or colorless crystals, it also occurs in a variety of colors. These color variations are often due to impurities and trace elements present during the crystal's formation. Some popular colored quartz gemstones include amethyst (purple), citrine (yellow), rose quartz (pink), and smoky quartz (brown). Pleochroism: Certain varieties of quartz exhibit pleochroism, which means they can display different colors when viewed from different angles. This optical property adds depth and interest to the gemstone, making it visually appealing. Availability: Quartz is one of the most abundant minerals on Earth, making it readily available and relatively affordable compared to some other gemstones. Its widespread availability contributes to its popularity as a gemstone. Versatility: Quartz is a versatile gemstone that can be faceted, carved, or cut into various shapes and sizes. Its versatility allows for a wide range of jewelry designs and applications. These properties, combined with quartz's beauty and versatility, contribute to its status as a popular gemstone used in jewelry, ornaments, and various decorative objects.

A cabochon cut quartz refers to a particular style of cutting and shaping a quartz gemstone. The term "cabochon" (pronounced kah-buh-shawn) comes from the French word "caboche," which means a small dome or rounded shape. In this type of cut, the quartz is shaped into a smooth, convex form with a flat back and a rounded or domed top. Unlike faceted gemstones, which have multiple flat surfaces and angles, cabochons have a curved surface that showcases the stone's natural color, patterns, and inclusions. The smoothness of the cabochon cut gives the gemstone a polished and glossy appearance. Quartz is a popular material for cabochons due to its abundance and wide range of colors and varieties. Some common types of quartz used for cabochons include clear quartz, rose quartz, amethyst, citrine, and smoky quartz. Cabochon-cut quartz gems are often used in jewelry, such as pendants, earrings, rings, and bracelets, and they can be set in various metals or combined with other gemstones to create unique designs.
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
Some prestigious brands of luxury watches for women include: Rolex, Faberge, TAG Heuer, Cartier, Vacheron Constantin, Van Cleef & Arpels and Montblanc.
The two main categories are quartz and mechanical, with automatic watches being a subcategory of mechanical watches. However, there are hybrid types that uses some form of combination between the two.Quartz: uses a battery of some sort (replaceable battery, rechargeable battery that are charged by wearing it or leaving it exposed to light) to drive an electronic circuit that control a vibrating quartz crystal (which vibrates at a bit over 32KHz).Mechanical: One of the oldest forms of timepieces - using a wound-up spring and a clever gear system that consistently distributes power (called escapement) to the hands. Usually these will be hand-wound only through the crown.Automatic: A mechanical watch with extra mechanisms that allow it to wind the spring by itself using the natural motions of the wearer.Mechatronic: A quartz watch with a mechanical chronograph (stopwatch).Spring Drive: A technology developed by Seiko that uses a mechanical power system to drive quartz-based electronics which then controls the delivery of the power system.

LeGant is a trademark used by Montgomery Ward department stores for watches produced under contract for sale in their chain. The watches were initially made in Switzerland, and will bear 'Swiss Made' on their dials and movements. Some models, such as the 'QS' were early 'electric' watches, not to be confused with 'electronic' watches, and were an evolutionary step between classic mechanical watches and modern quartz electronic watches. These movements utilized a balance wheel mechanism for timekeeping, as do fine mechanical watches, both vintage and modern. However, the watches were powered by battery (rather than the coiled mainspring to store power, as done in mechanical watches). This hybrid electro-mechanical movement helped to overcome the problem of extremely short battery life in the first electric watches. The Le Gant name was sold to Seiko in the early 1990's and watches from that era specify 'Japan Mov't', etc. Production was later ceased.

Quartz, is made up of silica and oxygen,it is one of the most common minerals on Earth. Billions of people use quartz every day, but few realize it because the tiny crystals they use are hidden in their watches and clocks. What do the clear or whitish crystal rocks found all over the world have to do with timekeeping While it's interesting to think that the quartz you find beautifying a landscaped lawn is also in your wristwatch, most of the quartz in electronics is synthetic, and specific quartzes can be created with specific frequencies for specific functions. Some materials, such as certain ceramics and quartz crystals, can produce electricity when placed under mechanical stress. The ability to convert voltage to and from mechanical stress is called piezoelectricity. Quartz crystals maintain a precise frequency standard, which helps to regulate the movement of a watch or clock, thus making the timepieces very accurate. Quartz is also used in radios, microprocessors, and many other technological and industrial applications.
A quartz clock is a clock that uses an electronic oscillator that is regulated by aquartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Quartz timekeepers are the world's most widely-used timekeeping technology, used in most clocks and watches, as well as computers and other appliances that keep time.Source: http://en.wikipedia.org/wiki/Quartz_clock

Quartz is a highly abundant material and has been used in a plenty of applications. Powdered quartz is used in making porcelain, scouring soaps, sandpaper, and wood fillers. Because it is a primary ingredient in sand it is also used to make glass & labware, silica brick, cement, and mortar. Ground quartz is used as an abrasive in stonecutting, sandblasting, and glass grinding. We are the leading Quartz Powder manufacturers in india.
Japanese movement watches are a good quality, but over-all a Swiss movement is the best. Some good Japanese mechanical watch brands are Citizen and SEIKO.
Some very durable diving watches include Invicta Pro Diver, the Seiko SKX series, Citizen Eco-Drive Professional's Diver's Watch, the Aquagraph Wenger Deep Diver Swiss Quartz, and Reactor Dive Watches. Diving watches can be very expensive, however, but the more you pay for a diving watch, the better quality it may be!
Quartz is a mineral. No other minerals contain quartz.
