Let customers speak for us
excellent customer service
Joseph at Diamond Lab was extremely helpful and made choosing the engagement ring and stone an absolute breeze.
For anyone who is hesitant of buying a ring online, I would seriously suggest Diamond Lab. They were fast, responsive and met my absurd Christmas time frame requirement.
Choosing a stone, they explained everything I was to know about clarity, colour & grading. No stone was left unturned when it came to these guys. My Fiancé absolutely loved it and I can’t thank Joseph at Diamond Lab enough.
This company is excellent to work with. Brilliant ring and quick to reply to everything.
Joseph was absolutely fantastic! I called him with a couple of ideas for a custom ring. He provided some great ideas and gave me thorough time frames as to cost and timeframe around delivery, as I live interstate. The design process was easy, as Joseph was happy to pass on all minor changes that I was after and assure me that this wouldn't affect the delivery date. The ring arrived on time and was absolutely perfect. Honestly don't know what I would have done without Joseph's amazing help!
Amazing ring! Perfect communication from the maker!
Absolutely beautiful. I cannot stop staring at my engagement ring. It’s pure perfection.
Best engagement rings of great quality, beautiful design. Friendly customer service. 100% recommend!
Ordered a Moissanite Tennis Bracelet. It was made to order in just a few short weeks. Overall quality and finish was very high especially the clasp which locks in tight and seamlessly.
My wife loves it
My experience shopping with Diamond Lab was fantastic from start to finish. The communication was clear, the team was incredibly helpful, and the quality of the jewellery exceeded my expectations. I really appreciated the personal guidance in choosing the right stones and settings, it made the process feel effortless and special.
Delivery was quick, the packaging was beautiful, and the attention to detail was evident in every aspect. I wouldn’t change a thing, but I’d love to see even more ready-to-ship options available in future. Overall, I’m thrilled with my purchase and will definitely be returning for more pieces.
Absolutely stunning! I purchased a pair of 2ct total weight lab diamond studs from Diamond Lab, and they completely exceeded my expectations. The brilliance rivals natural diamonds, crisp, bright, and full of fire. The craftsmanship of the setting is flawless, and they sit perfectly on my ears with just the right amount of sparkle for everyday wear or special occasions.
Customer service was exceptional too, Nicole helped me choose the perfect size and setting, and the packaging felt luxurious from start to finish. I’ve received countless compliments already. If you’re considering lab-grown diamond studs, these are a must. Elegant, ethical, and worth every dollar.
If you’re looking for high-quality jewellery and exceptional service, I can’t recommend Diamond Lab enough. Thank you to Joseph for making such a special purchase such an enjoyable and memorable experience.
Got my engagement ring from and it is absolutely stunning and incredible quality! Highly recommend
I brought in an idea based on a few Pinterest photos, and the Diamond Lab team brought it to life better than I ever imagined. The craftsmanship is unreal, and the diamond quality was better than anything I saw in traditional stores. I love that everything is made to order, and the fact it’s all ethical makes it even more special. So grateful I found you guys
We were nervous about buying a ring online, but Diamond Lab made it incredibly easy. We had a virtual consultation, and everything was explained clearly. The CAD design process was fascinating and gave us full confidence. The finished product was flawless, and the packaging was beautiful too. You can tell they care about every little detail. Thank you so much!
