Welcome to A. Wiener and Company's website. Our company was established some 60 years ago, when Ascher Wiener arrived in New Zealand. He built up the company rapidly, soon achieving a reputation for honesty and accuracy. He was helped greatly by family ties in the major centres of Antwerp, South Africa, New York and Israel. The Australian operation began in 1965 in a small way and over the years we have become one of the key companies in the Australian diamond industry. Our vision is always to be at the forefront of changes and trends in the diamond market, which is evident in our range of loose diamonds and diamond jewellery.

We have a comprehensive range of loose diamonds in all shapes and sizes, colours and purities. Our consistent fine make is found in goods from vvs to pique quality. We pride ourselves in our investment in larger diamonds and therefore carry a very large stock of 0.50ct-10ct, with and without certificates. We also specialise in matching fancy shapes, including kites, trapezoids and half moon shapes.

Whether you are a manufacturer, single-store retailer or a chain operation, we can help you source the diamonds you need. We are constantly travelling to all the world's diamond centres in search of new stock, and are always looking for those "hard-to-get" items. We can therefore offer competitive pricing as a result of our strong buying power. We believe in long term relationships in business, and indeed, we are dealing with some third-generation customers, an achievement of which we are proud.

Our staff has an accumulation of over 100 years of trade experience and our representatives are always keen to make new contacts. Ask us how we can help you with your diamond and jewellery business.
