Happy Xmas!"

Googled and thankfully found this place. They saw me the morning I called and I felt really comfortable with the selling process. Besides the engagement ring I also sold the gold jewellery from my ex. Happy days!"

Rachel Barnes, Five Dock, September 2014

On recommendation, I went to Sydney Diamond Buyers and was really happy with their expertise and their pricing."
