I had been searching for months for the perfect emerald stone for my engagement ring and spoke with many dealers both in Sydney and overseas before I finally came across Mauro at Colonial Gemstones.

The moment I saw my Muzo Colombian emerald, I knew my search was over. Mauro was patient, genuine and very easy to communicate with throughout the whole process, which made such a difference when making an important purchase like this.

Because of the trust he built, I now feel completely comfortable entrusting Mauro to design both my engagement ring and my future wedding ring. It’s been a really special experience and I’m looking forward to creating more beautiful jewellery pieces with Mauro and the team in the future.

I had such a great experience with Colonial Gemstones and Mauro! The whole process was super easy and communication was great the entire time. Mauro made sure I was really happy with my ring — the emerald is absolutely beautiful and the whole ring turned out even better than I imagined. They were also really understanding and worked with my budget, which I really appreciated. I’m so happy with my ring and would definitely recommend them to anyone.

Exceptional experience with Colonial Gemstones! Mauro’s customer service is excellent. He took the time to explain every detail, answered all my questions, and even accommodated FaceTime meetings. What really stood out was his willingness to respond outside business hours, reassuring me and addressing my concerns. He's pleasant, honest, and genuine - a true gem in the industry! We're looking forward to doing business with them again. Highly recommend Colonial Gemstones and Mauro’s expertise.

Mauro was exceptional in going above and beyond to fix an emerald that had been chipped, and also reconditioning the stone so it was better than before. And checked in afterwards to make sure we were happy with the end result. So happy to have found you and will certainly be back in the future. Thanks again!!

We absolutely love the emerald pendant Mauro arranged for us! The stone is stunning, as is the pendant setting which he arranged to be made up for us (it reflects our requested design perfectly). We really appreciated Mauro's advice on emeralds which helped us to select the stone. Mauro went above and beyond at every stage, even posting the pendant to us when we could not meet up in person. Thank you, thank you!

I recently bought a beautiful emerald gemstone from Colonial Emeralds, initially Mauro had sent me a gemstone through post but when I physically saw it I wasn't entirely happy but Mauro was kind enough to take it back and sent me a different gemstone. He made sure that I was completely happy it. Mauro also provided a certificate of authenticity, assuring me of its natural origin, packaging was secure. If you're looking for high quality emerald gemstone, I highly recommend Colonial Gemstones.

We had an incredible experience getting my custom emerald engagement ring created, and I couldn't be more thrilled with the final result. From start to finish, the customer service was exceptional. Mauro took the time to understand exactly what I wanted, offering expert advice and guidance on the design, stone selection, and overall look. He really listened to my vision and brought it to life in a way that exceeded my expectations.

Throughout the entire process, Mauro was communicative, patient, and attentive, making sure I felt comfortable and kept my fiancé informed every step of the way. The craftsmanship of the ring is flawless, and the emerald is absolutely stunning. It’s clear that a lot of care and attention to detail went into every aspect of the design.

Excellent experience! Mauro's Colombian emeralds are absolutely beautiful. He was happy to share his knowledge of emeralds with me, took the time to chat through different stones, different sizes and cuts. I purchased a necklace that was the most exquisite green I have ever seen - I will be wearing it for years. I am already thinking of my next purchase! Thank you again Mauro for your time and knowledge, and making the process enjoyable💚

Could not have been more happy with my experience with Mauro at Colonial Gemstones.

I recently bought an engagement ring for my partner from Mauro, and I would recommend him to anyone looking for high-quality jewellery and exceptional service.

From the first meeting, I was comfortable with his knowledge and authenticity. He was patient throughout the process, even when I asked for changes to be made. He was truly committed to getting the outcome that I desired.

The end product was a beautiful emerald ring that my partner loves.

Mauro, thank you very much mate. It was an absolute privilege meeting you and having you guide me through this process. I truly appreciate it.

Excellent experience. I really enjoyed selecting the stones and working with Mauro to achieve the desired design. The process is nice and quick from describing the design, to receiving the sketch, making minor tweaks and then making the ring.
The photo does not do the ring justice! In real life it sparkles and the deep green emeralds are nice and clear.
Thoroughly recommend!

I purchased emeralds from Colonial Gemstones to make a pair of earrings for my wife. Mauro, the owner was extremely approachable, generous with his knowledge. He was professional, direct and provided excellent customer service. I also needed his help to introduce me to a jewellery maker who can carry out my design. Mauro gave me very practical design suggestions and facilitated the transformation of the stones into stunning jewellery. I am an international client from Toronto Canada. Long distance business has it distinct challenges. However Mauro provided prompt communication. He gave me prompt updates throughout the whole design and making process. It was a genuine pleasure to work with him. I give Mauro my highest recommendation to anyone looking for Columbian emeralds. Testimonial aside, the most important thing is my wife was blown away by the end result. Happy Wife Happy Life as they say. Note: Photo can never recreate how great the earrings look with the naked eyes.
