Difference: 925 sterling silver, Thai silver, Tibetan silver, Argentium Sterling silver
925 sterling silver
Is 925/1000 silver with 75 thousandths of copper silver, silver is an internationally recognized standard, as silver standard. 100% of the silver is relatively soft, making could not be formed, made of silver inconvenience, and relatively easy to "oxidation", is usually platinum plated 925 silver (white rhodium) to prevent Silver oxide or sulfide in the case of yellow black, not platinum plated 925 silver, known as the “prime bank.” Nowadays, 925 sterling silver jewelry take 50% parts of world jewelry markets.

Argentium Sterling silver
Argentium Sterling silver is a modern sterling silver alloy which modifies the traditional alloy (92.5% silver + 7.5% copper) by replacing some of the copper with the metalloid germanium. As it retains the 92.5% silver content of the traditional alloy, it is still referred to as sterling silver.
Germanium was discovered to impart the following properties to sterling silver:
• Fire scale elimination
• High tarnish resistance
• Precipitation hardening and simple heat-hardening properties
• Increased ductility
• Increased thermal and electrical resistance (making alloys suitable for welding and laser forming)
• Environmental advantages (associated with not having to remove or plate over fire scale)
Many of these properties significantly affect the traditional methods of working silver. For instance the absence of fire scale eliminates tedious and time-consuming steps required by the silver worker using traditional sterling silver. It also eliminates the need for plating the final product which is often done on manufactured items because of the problems introduced by fire scale. Tarnish resistance is of significant importance to both silver workers and the wearer of silver jewelry.
