1. About 316 Stainless Steel Jewelry

In metallurgy, Stainless Steel is defined as a ferrous alloy with a minimum of 10.5% chromium content. The name originates from the fact that Stainless Steel stains, or rusts, less easily than ordinary steel. Stainless Steel has higher resistance to oxidation (rust) and corrosion in several environments. High oxidation resistance in air at ambient temperature is normally achieved with additions of more than 12% (by weight) chromium. The chromium forms a layer of chromium (III) oxide (Cr2O3) when exposed to oxygen. The layer is too thin to be visible, meaning the metal stays shiny. It is, however, impervious to water and air, protecting the metal beneath. Also, when the surface is scratched this layer quickly reforms. This phenomenon is called passivation by materials scientists, and is seen in other metals, such as aluminium. When Stainless Steel parts such as nuts and bolts are forced together, the oxide layer can be scraped off causing the parts to weld together. When disassembled, the welded material may be torn and pitted, an effect that is known as galling. There are different types of Stainless Steels: when nickel, for instance is added the austenite structure of iron is stabilized. This crystal structure makes such steels non-magnetic and less brittle at low temperatures. For higher hardness and strength, carbon is added. When subjected to adequate heat treatment these steels are used as razor blades, cutlery, tools etc.

The AISI defines only Type 316 for food and surgical Stainless Steel uses; Alloy addition of molybdenum to prevent specific forms of corrosion; equivalent to ISO A4.

The ASTM & ISO have a standard for wrought stainless steel used for surgical implants. It is called ASTM F-138. The ISO specification 5832-1 is included in this spec.

The material composition covered by this specification has been employed successfully in human implant applications in contact with soft tissue and bone for over a decade

The number 316 stands for the type of stainless steel; it's basically a formula for the mixture of elements that make up this alloy. The L stands for a low carbon content

316L stainless steel - a hard wearing alloy highly resistant to corrosion and chemicals. Stainless steel is virtually maintenance free and is highly resistant to scratches. 316L Stainless Steel provides superior corrosion resistance and higher resistance to pitting. Stainless steel can be worn by many people who cannot wear other types of jewelry due to allergic reactions. 

All of our stainless steel jewelry are made of 316L stainless steel..

All stainless steel jewelry is polished to a mirror finish, bright. Shiny. classic appeal.

It has a look that is clean, modern, elegant, ,Strong. Durable. With a charm all its own that keeps delivering year after year. It has the advantage of being a more rugged allow than gold or silver as it is nearly indestructible.

2. About 925 Sterling Silver Jewelry

Pure silver is .999 fine , also called fine silver, is relatively soft, very malleable, and easily damaged so it is commonly combined with other metals to produce a more durable product. The most popular of these alloys is sterling silver, which consists of 92.5 percent silver and 7.5 percent copper., commonly known as Sterling silver and is quality stamped .925, SS or Sterl.

Although any metal can make up the 7.5 percent non-silver portion of sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness and durability without affecting its beautiful color. The small amount of copper added to sterling has very little effect on the metal's value. Instead, the price of the silver item is affected by the labor involved in making the item, the skill of the craftsperson, and the intricacy of the design Because pure silver is so soft, it should only be used when malleability is required, such as in handcrafted jewelry featuring weaving and other intricate designs. Sterling silver is most often used for jewelry and household accessories because of its combination of beauty and durability. It is the most common metal used in jewelry today.

The sterling silver jewelry is made from this sterling silver, which is a white and highly reflective precious metal. It is of superior quality, which reflects in its look and feel. Although less durable than stainless steel and other precious metals, sterling silver is often employed in watches that coordinate or look like sterling jewelry. A protective coating may be added to prevent tarnish. Sterling silver jewelry is not very cheap, yet is also not beyond reach. It has a very distinctive look and can be easily distinguished. There is no mistaking the high reflective shine of this jewelry, which is one of its characteristics trade marks.

It adds a sophisticated charm to your personality. Sterling silver jewelry has a very stylish look and lends an incredible elegance to your entire look. The inedible stamp of quality along with the chic sophistication makes it a wonderful must have product. It is a very versatile ornament which crosses all barriers of age, cast, creed etc. It can be worn by anyone whether young or old.

Sterling silver jewelry has a unique air of class, sophistication and style surrounding it. It is a wonderful thing to own and also to gift to people who matter. It says a lot about your personality and taste. Wearing sterling silver jewelry can immediately enhance your over-all persona. It is available for both men and women being one of those essential pieces of jewelry which you must have in your collection.

With proper care, your fine quality silver will last a lifetime. To minimize scratches and other damage, store your silver jewelry either in a cloth pouch or in a separate compartment in your jewelry box. Avoid exposing your silver to household chemicals when cleaning with bleach or ammonia, or when swimming in chlorinated water, as these chemicals can damage silver.

3. About Ring Size

Ring size

In the United States and Canada, ring sizes are specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch (0.8128 mm) in diameter, or roughly 1/10 inch (more precisely, 0.1005 in or 2.55 mm) in inside circumference.
In Europe (excluding Ireland and the United Kingdom), ring sizes are specified using a numerical scale, with half sizes.
In Ireland, the United Kingdom and Australia, ring sizes are specified using an alphabetical scale, with half sizes.
In Japan, ring sizes are specified using a numerical scale that only has whole sizes.
In Switzerland, ring sizes are specified using a numerical scale, with quarter and half sizes.
In Germany, ring sizes are specified using actual internal diameter in mm. (the same as ISO)
The ISO standard for ring sizes is ISO 8653:1986, which defines standard ring sizes in terms of the inner circumference of the ring measured in millimetres.
