We contracted with Mos Holdings (also known as Complex Industries) the head office in Hong Kong but factory is in China, to make my custom earrings. Their address is Company: Complex Industrial Company Limited
Address: 20F, Unit F & G Gold King Ind Bldg., 35-41 Tai Lin Pai Rd Kwai Chung. The other websites are: http://www.complex.com.hk/e/default_home.asp and also http://www.mosholdingsltd.com/sc/. The order did not look like the samples. First they were late by 1 month in making the earrings and in that time had mislead me about when the earrings would be finished and pushed back the completion date several times. The also made the earrings in the wrong plating- I asked for 18 K gold, rose gold plated earrings but they gave me 9K gold earrings which were pale and looked terrible. The earring pins broke off easily and they did not plate the earrings well so the base metal was exposed and so it looked rusted. The engraving was done incorrectly on all the earrings as well and bad quality glue was used, so CZ stones would fall off easily. Out of 1,312 earrings that I ordered there were 879 earrings that were faulty. They refused to give me a refund or even discuss the matter and I have still been unable to talk to a manager.
This company seems very good as they do very good samples, but when the actual order is sent - the earrings are made so faulty that they cannot be sold.
Please do not be fooled even though they say they make jewlery for big brands- they are fraudulent.
