From the 8seasons.com website:
"These 925 Sterling Silver Imitations have hallmarked â€œ925â€ as the genuine 925 silver items, but the silver purity is not as high as the solid sterling silver.
Our 925 imitations are made of copper plated with a layer of silver. The quality of these silver imitations is determined by the thickness of the silver coating. We classified our 925 silver imitations into three grades just based on their silver plating.
Grade A: 925 Stamped--White Copper Plated with Heavy Real Sterling Silver
Grade B: 925 Stamped--White Copper Plated with Thin Silver
Grade C: 925 Stamped--Copper Plated with Thin Silver
Why we offered 925 sterling silver imitations?
We are always offering solid genuine sterling silver items, but some of our customers told us that, their customers (also the end consumers) do not wish to spend a lot money on solid stering silver, but they also like the 925 stamped silver items at inexpensive price. Based on this marketing requirement, so we cooperated with our factory developed these 925 Silver imitations."
I wondered how some of the Ebayers could offer stamped .925 sterling silver so cheaply. Not everyone may be using 'imitation' stamped 925 but I believe many of them are - and may not even be aware of it!
