Semi-Precious Stone Earrings–A Fresh Alternative

/in , , /by

Color in jewelry enhances a wardrobe, but if you don’t want to wear costume jewelry–or if you cannot wear it due to metal sensitivities–consider fashion jewelry.  And not just fashion jewelry–handmade fashion jewelry with natural elements.

Fashion jewelry?  Quality jewelry made with components that are sterling silver, gold, or gold-filled.  Natural elements?  Yes, natural elements–semi-precious stones, nuts, seeds–with an endless variety.

Have you sworn not to wear costume jewelry?  Are you a little skeptical about the quality of jewelry that is handmade or jewelry that is not classified as fine jewelry?  Let me introduce you to some beautiful, semi-precious stones that will give you something to think about when it comes to quality fashion jewelry.

Semi-precious stone earrings are just one option of components for jewelry that is natural.  The colors and shapes of semi-precious stones are endless.

Are you looking for pink accessories?  Pink rhodonite stone earrings are absolutely lovely.  Rhodonite is a beautiful pink stone (Rhodon is Greek for rose) that appears to have black veins running through it.  The rhodonite stone is feminine yet very durable, and it comes in a variety of shapes.   You will find quality handmade rhodonite earrings available with sterling silver or gold-filled ear wires.

Or perhaps you want beautiful earrings for your black cocktail dress. Consider handmade rainbow obsidian earrings.  Rainbow obsidian is black–a by-product of lava.  This beautiful stone shows flashes of black, blue and green–casting off a beautiful iridescence in the light; hence it’s name: rainbow obsidian.  Rainbow obsidian handmade earrings and cocktail hour make a perfect match.

Are you casually dressed in red?  Have ever seen handmade red sponge coral earrings? Sponge coral is porous like a sponge.  If you really like the natural, organic look, you’ll love sponge coral earrings.  When they are handmade, these casual but classy earrings can be found in sterling silver and gold-filled ear wires.

Blue lapis.  Blue lapis stone earrings are a favorite with women who like semi-precious stone jewelry.  Whether you’re dressing up or down, these vibrant blue earrings will gorgeously accessorize your wardrobe.

The beauty of natural stones far surpasses anything that costume jewelry has to offer.  Expand your jewelry collection, but don’t leave nature out this time.  Consider quality, handmade jewelry with natural elements.  If you’re uncomfortable, ease into it with semi-precious stones.  You won’t regret the move.

Aluminum die casting design

1.    There are a variety of casting methods to produce aluminum die casting and magnesium alloy casting, because of the low melting point of aluminum and magnesium alloy. So in the design of their structures, you should consider which kind of casting method to cast this casting at first, in order to consider the relative structural manufacturability.
2.    The aluminum alloy and magnesium alloy casting should try to use thin wall structure, and strive to the balance of wall thickness. This is helpful to prevent shrinkage cavity shrinking and improve the strength of the metal castings. But you can also thicken some part for the unbalance of wall thickness to set feeding aluminum and magnesium alloy casting. This can help filling shrinkage to guarantee the quality.
3.    The aluminum and the magnesium alloy is easy for oxidation and suction. The density is small, so as to make the static pressure of the metal fluid is small and be difficult to exhaust. Therefore, aluminum and magnesium alloy casting is easy to generate hole and oxidation slag, reduce the mechanical properties and gas tightness. So designing the casting structure should avoid big plane, and the transition should be gentle, and avoid causing the turbulence of metal liquid.
4.    Because of the low melting point of the aluminum and the magnesium alloy, to those castings that have some certain gas tightness requirements, you should avoid using core support to fixed core when design.
5.    The compression strength of magnesium alloy is higher than its tensile strength. So you should adopt asymmetrical section and box to undertake the compressive stress.
6.    Pay attention to adopting the method of double metal die casting and potting casting to solve the problems in the structural design of the aluminum alloy and magnesium alloy.
7.    The corrosion resistant of magnesium alloy is poor. Often use surface treatment to improve the corrosion resistance of magnesium alloy castings.

Different Types Of Casting To Suite Your Casting Necessity

There are different processes that can be used in creating complex shapes of metals parts and one procedure is through casting. Casting is a manufacturing method wherein a liquid material is transfer

red into a mold, usually following a hollow cavity of the desired shape, and then allowed to solidify afterwards. It has been used even in the past and one example or type of casting is die-casting.

The die casting method is a process of forcing molten metal under high pressure into mold cavities similar to permanent mold casting. It best suites the purpose of making small to medium sized parts fashioned with good and precise details. By-products of this method are furnished with fine exterior finish and dimensional accurateness. Most materials used in this method are metals such as zinc die casting, copper, and aluminium die casting and magnesium die casting.

Another form of casting which is considered to be the most popular and simplest type is sand casting. It is a technique that has been used for many centuries now. Sand casting is a process of forming a mold out of a sand mixture through pouring a casting liquid into a desired shape. This type of casting allows manufacturers to create large number of products in such a small range of production expenses. Most metals are caste depending in the type of sand used for the molds in this method.

An additional process that can be also used is Plastic molding. It is a manufacturing technique in making parts from both thermoplastic and thermosetting plastic materials for production. It includes plastic injection molding wherein molten plastic is injected at high pressure into a mold, which is the opposite from the product’s actual shape. Example by-products of this method are bottle caps and outdoor furniture.

Moreover, a further technique is cold forming. It is also known as cold forging. Cold forming is a manufacturing procedure in which a metal is shaped at an ambient temperature to produce metal components in a definite shape. The techniques usually involved in this procedure are bending, cold drawing, cold heading, coining extrusion, thread rolling and others.

Some benefits of cold forming are enhancements in the component properties of the product because the grain structure of the material is being elongated during the formation process wherein it is forced to follow the structure and as a result its’ strength is increased. Another benefit of cold forming is that the aesthetic finish of the components gives out a brighter facade and formed with a consistent high tolerance. These somehow reduce the necessity of complex finishing and polishing.

These are only some of the different kinds of casting. Other types of casting aside from die-casting, cold forming and sand casting of metals are plaster casting, shell molding, investment casting, permanent mold casting, centrifugal casting, continuous casting and casting of plaster, concrete, or plastic resin. Each type of technique has specific and unique routine that allows you to produce superior outcome and high-quality by-products to best suite all your casting needs for your manufacturing use.
