Diamondport
We're here to help make the most important decision of your life as smooth as possible. We'll work with you to create a beautiful diamond engagement ring that she'll love - almost as much as she loves you. Visit us now at our Brisbane studio which is conveniently located in the Queen Street Mall to see some of the best engagement rings Brisbane has to offer.

At Diamondport Brisbane, one thing is for sure: whether you want a custom engagement ring or one of our beautiful designs, we guarantee you and your partner will love it. At Diamondport, we are diamond merchants, Brisbane engagement ring designers and manufacturing jewellers. We'll work with you closely whether you're in Brisbane, or located elsewhere, to design your engagement ring to reflect one of the most important moments in your life.
Services
We import some of the finest quality diamonds in Australia and specialise in custom engagement rings, wedding rings and eternity rings, all crafted right here in Brisbane. Diamond Merchant Ashley Portas loves 'making dreams come true' by helping clients to design their dream engagement ring. Clients say we're great listeners, that the process is informative and fun.
It's really hard to tell without having an experienced diamond merchant on your team. Have a look at our guide on GIA certified diamonds to help you understand what makes a quality diamond. We do suggest being wary of information you read online regarding diamond quality - there is a lot of information that is incorrect and misleading.
Your diamond engagement ring and wedding ring are beloved pieces of jewellery that you intent to have for the rest of your life. But wearing them every day can leave your jewellery looking lacklustre. Regular cleaning is essential to not only keep your ring sparkling but to also protect it from further damage.
Making sure your ring fits perfectly is all part of our service at Diamondport. We can resize your engagement, wedding, eternity and dress rings so that they sit just right. Ring resizing and all our other ring care services are carried out in our Brisbane studio located in Queen Street Mall. Resizing a ring takes less than a week, and we offer a same day service in some cases.
So many guys surprise their partner with a proposal yet how can you surprise her with the correct ring size? It would be a tad awkward if you were to get down on one knee only to realise that the ring doesn't fit past her first knuckle. Engagement ring sizes don't need to be a guessing game. If you can get a ring that you can bring into the appointment, that's great.

My fiancé worked with Ashley and the team at Diamondport to design my dream engagement ring, I was blown away by the elegant pear cut and the custom basket design. Beau proposed about a month ago and every day since I catch myself staring at it with awe and pinching myself that this ring is mine forever. I met with Ashley soon after our engagement for a post proposal follow up session where he provided me with a range of information and tips for ring care.
I would definitely recommend this company for those in the market for their forever ring.

Outstanding service by Jason and the team at Diamondport who have recently created a stunning custom engagement ring for me. I was recommended them by a friend and I would now recommend them to anyone else thinking of purchasing an engagement ring. The team helped bring to life my designs and ideas to create a perfect ring for my fiance.

Would definitely recommend Diamond Port to anyone wanting a stunning engagement ring for their loved one. My ring was spectacular and shins in any light, I am totally in love with it. The quality is second to none. The follow up meeting was professional and I was shown how to care for my new precious ring. Choosing wedding bands was great, Ashley can accommodate to all tastes in style. Was a very intimate and personal setting to make your choices.

A little background, myself and my wife Tara have been married for 20 years and I wanted to mark the occasion with an eternity ring. I had a pretty good idea what I wanted and with the excellent advice and assistance from Ash and Jason they nailed it. Custom made and ready for collection within 4 weeks (just before Christmas). Top job guys, Tara loves your work and is regularly caught extending her hand and examining the ring when she thinks no one is looking. Could not ask for better service or workmanship. For anyone looking for that special ring, I would strongly recommend visiting Ash and Jason

I just collected my beautiful engagement ring today and had a wonderful experience with Diamondport. My partner and I went to see Ashley with zero knowledge about diamond but he walked us through everything. The whole process was amazing, very well communication and advice! I received lots of compliments on my ring. Cannot thank Diamondport enough for making me such a gorgeous ring! Highly recommend!!! 💍❤️

Jason and Ashley at Diamondport were so lovely to work with when buying my engagement ring. My fiancé and I were very comfortable in our consultation and follow up appointments. Having been to other jewelers and feeling out of place, we immediately felt a difference with Jason and Ashley as they were so down to earth, honest and realistic in balancing budget, design and wishes.
Would definitely recommend to friends and family!

My partner proposed to me recently with a custom made ring from Diamondport. After questioning him about the who what where of this stunning ring he told me about the whole process he went through to make the absolute most perfect ring I could imagine. I never knew what ring I would want one day, all I knew was white gold and simple. Turns out my partner knows me better than I know myself. The ring was pure perfection, simple with beautiful added detail on top and bottom that I had never seen before. Thank you Ashley at Diamondport and the incredible team of Jewelers that help my man create this

I recently lost the diamond from my 17 year old engagement ring...then found it in the back seat of the car! I took the lucky rock to Ashley at Diamondport, slightly nervous about letting it go. It couldn't have been in safer hands. The diamond was set in a completely new ring and is now a stronger and more beautiful version of its old self. I highly commend Ashley and the team at Diamondport for their professionalism, expertise and high quality craftsmanship. Trustworthy too and locally made. The whole process from start to finish was very professional with regular progress updates.
Thanks a

Diamondport have once again created exceptional masterpieces! My (now) husband worked with Ashley to create a custom made engagement ring that is absolutely stunning so it was no brainer for Diamondport to be apart of creating our wedding bands too. And they're perfect! Thank you Ashley and team, there's no where else we would turn to! xox

Ashley has helped me with the Engagement ring from start to finish, a full custom ring and my partner could not be happier with the finished product. We loved Ashley’s work and returned to get both our wedding rings made, they’ve turned out perfect. Could not recommend a better place to get your rings made than Diamondport!

After searching for Brisbane's finest jeweller, it did not take long before I stumbled accross Ashley and his team at Diamondport. Upon reading raving reviews and the history behind the company, I was drawn to the idea of an intimate enterprise. So, I hastily made an appointment.
Through comprehensive design visits and ongoing consultations with… Ashley, we created a stunning and vastly unique engagement ring perfect for my picky fiance.
Following my first phone call, right up to the post-proposal appointment, I was met with the utmost care and consideration. I felt so welcome and well regarded

Incredible experience with Diamondport, in all my dealings with Diamondport, my expectations have been exceeded. Ashley is incredibly passionate about what he does, and takes care of you, irregardless of whether you end up being a customer or not (due to unforseen circumstances, I was unable to go through with my purchase initially). But I know EXACTLY where I will be going when I need to make my engagement ring decision!
