Ramzi & Co. is one of Australia’s fastest-growing manufacturers, and online retailers of engagement rings and wedding bands. We mainly operate online as this allows us to cut overhead costs and pass significant savings to our customers. Rest assured, you receive a high-quality product at a much better price than you would from a physical jewellery store.
Whether you seek a great selection of filigree engagement rings, pave rings for a special occasion, diamond halo rings to celebrate an anniversary, or stunning statement pieces like sapphire rings, you will find them all right here.
On top of increased selection, our healthy business means we bring diamond engagement rings, wedding rings, sapphire rings, morganite rings and tanzanite rings to you at very competitive prices. Every piece is hand-tended and crafted, available in a full range of sizes, styles, and settings.
Our involvement in every step of the manufacturing process means we can create custom orders just for you that even cost less than cheap engagement rings online from other retailers.
All of our rings, feature gems and diamonds sourced directly from reputable mines in conflict-free areas. You can shop with us guilt-free.

To form a ring shape, push the end of the ring sizer through the buckle as you’d do with a belt.
Wear the ring sizer on your finger and adjust to a comfortable fit while making sure it can still slip back over your knuckle.
When you’ve found your best fit, the letter that is pointed at by the arrow is your ring size.
Let’s get you a Ramzi & Co. free ring sizer.
