Over our extensive career in the jewellery industry, we’ve had the rare opportunity to view and collect some very unique gemstones & naturally coloured diamonds that are truly one of a kind visually. The kind of loose diamonds & gemstones that you could spend your lifetime searching for yet, never come across again.

Please browse through a selection of our featured loose diamonds for sale and watch this page for updates as we’ll be sharing with you some of our rare & collectable gemstones including; Padparadscha Sapphire, Plum Star Ruby, Tsavorite Garnet, Alexandrite, Purple Spinel, Tanzanite, and many more.

We are constantly excited and inspired to source the most beautiful gemstones from Australia and around the world for our clients, so if you’re looking for something in particular please don’t hesitate to get in touch.

Once you’ve selected your gemstone with us, you will then have the opportunity to have your ring designed & 100% handcrafted to world-class standards in the workshop of Edward Swaab, Award-Winning Designer + Master Craftsman. Each creation is designed around the loose diamond or gemstone through careful consultation with Edward, where we’ll be working back & fourth on design concepts until you’re 100% confident with his vision for handcrafting the piece.

If you’d like to discuss your requirements personally or arrange an obligation free consultation, please call us on 02 9689 3396 or send us an enquiry here.
