Our main mission to accomplish is to provide quality onyx blocks to our precious clients in all over the world.

Our quarries have been operated by our family companies which are Topaz Onyx Mining Ltd. and Oztas Marble Inc. since 1972. As the family's 3th generation we have taken over Oztas Marble Inc. from Mr. Hasim Ozcelik in year 2008 who is founder of company and believes that companies have to live forever.

Topaz onyx is manufacturing company and Oztas Marble is marketing and export company. Oztas Marble is not only marketing our own quarry stones, but also it markets our affiliated quarry stones, too. If any of our steady customers can address us some specific stone, we can outsourse that stone on our customer's behalf at bargain price because always quarry owners offer bargain prices to each other.
