Quality Diamond
Quality Diamond Plated Products was established by Robert St.Clair in 1976 in Chatswood, Sydney and continues to supply both local and overseas markets with high quality product.
Since Robert’s retirement at the end of 2019, Colin Christian and his family have continued the business. His experience in surface coatings have grown the business to a new level.
The business has been relocated to a new workshop in Barden Ridge NSW.
We specialise in non-standard and non-stock electro deposited tools and use only premium grits to provide the best quality possible in the industry today.
