Absolutely phenomenal. The love and effort that has been put into showcasing the wonder of Australian opals shines out as you move from showcase to showcase. The rendering that has been put into the plastering to resemble the walls and roof of underground opal mines is so realistic that one would be forgiven for forgetting they are in the middle of the city and not below ground in the desert in a hidden wonderland of opals.

Fell in love with a Opal Pendant and went home to think about wether I would buy it or not. Upon visiting the shop the next day the price went up from $1.400,- to $1.870,- as seen on the new price tag (even took photo’s the first day to show my mom). After confronting the shop manager with the price change he started making up excuses and telling us the prices had not been changed. Clearly showing he was very nervous and not happy seeing us again, obviously because we spoke to this same person a day earlier and discussed the $1.400,- shown on the price tag. We have viewed multiple Opal Pendants in this shop which prices were also changed with new price tags. ($650 to $870) We offered the Shop manager to buy the Opal Pendant for the price as shown a day earlier but he said he could not sell it at that price. Maybe the prices are up all the sudden due to summer holiday, no problem. But it would be good if they would be honest about it instead of lying to our faces.. at first it felt like a genuin shop (we’ve visited way worst, we thought) but I feel so betrayed after this experience

Great quality and amazing prices. The best opal business by far. If we add the kind owner and worker it makes of course the 5/5 score. Muchas gracias!

We bought a beautiful opal ring that will be a family heirloom. The staff were able to tell us about each piece with informed detail and did not try to push us into buying. I had it resized and Ron went above and beyond to make sure I had it for my birthday. Would definitely return for future purchases.

Very interesting! Not just beautiful jewellery, not just lovely staff. Very very cool! Opalised bone, plants, wood. Cooooool

Beautiful store and collection. Opal are expensive. It's great to learn about it but I don't think I would spend that type of money. But good place to visit.

Really cool pieces in the museum, very beautiful and one of the staff was very lovely and informative; lots of interesting facts. Jewellery is gorgeous.

We brought an overseas visitor to National Opal Collection. We researched various places but we were so impressed with the patience, expertise and attitude of the staff here. The opals are stunning; we left informed, respected and with three magnificent, lifelong gifts for our friend to take home for his wife and daughters. Highly recommended

War sehr interessant und für einen kurzen Abstecher durchaus lohnenswert

Cool opal store downstairs. Wife got a nice ring and I got to check out their interesting museum

Fantastic experience! I highly recommend. Beautiful & unique jewelry & the most friendly, patient & knowledgable staff in the World.

The personnel at the establishment was super to work with. She explained everything about opals and showed my wife and what to look for in buying opals. I highly recommended this establishment.

100% worth having a look. The guy who operates the store is an absolute legend, he's clearly extremely passionate and knowledgeable about opals and his collection. And there are some truely amazing opalised fossils among the collection. Would definitely recommend for anyone who enjoys geology, gems/minerals, history, fossils and of course beautiful jewelry

Have had such a great Shopping experience and learned much about opal gemstones. Here i found my wonderful ring- a memory to Australia. They have so much expertise and affordable prices. At the Airport (TRS) no Problems with the invoice they distributed to us. Thank you again and greetings from Germany to Ron.

Stumbled into this little gem. Went for a look. Very Interesting it was lovely to get some information about Opals. And the fossils that had turned into Opals. So many pretty stones ❤️

Excellent service, beautiful opal, sincere family business ! Highly recommend.

Staff were very friendly, Ron took the time to talk to us even though we were there just to look and not to buy. Beautiful collection of opals and interesting fossils.

An amazing store and collection!! The sales assistant was so lovely and informative. He explained so much to my friend and I about checking opal value and the shifting lights in the stones and geographical location of opals! Highly recommend this place they are so welcoming

Thank you very much for the conversations and your time. I had a quick look and came back a few hour's later as I fell in love with the jewellery and enjoyed the friendly interaction. Lovely regards from the last client you had today 😊

I received a ring with a white opal from my aunty as a goodbye gift as I was leaving Australia, the opal fell out as I was abroad but the company has replaced it for free and everything was done in a very timely manner, even though I was abroad! Special thank you to Kasumi who showcased impeccable customer service and took care of the whole situation! Highly recommend

Cool, stylish place mimicking a cave (mine). Little bit of history and beautiful products. You can see the technician cut and polish the stones as well. Very knowledgeable staff.

I've walked past this place countless times. Yesterday my boyfriend and I decided to have a look and were pleasantly surprised. There a nice selection of fossils and Amazing opal jewellery. I've never been very fond of it, but I hadn't realised the variety of colours. This place is a hidden gem in a busy city.

Great store with an amazing selection of opals. Was served by a lovely young man named Will who was extremely helpful. Would highly recommend!

Very educational session with Alex today. His patience and guidance allowed my wife to select the perfect black opal to suit her needs

Rude staff..Don’t waste your time and money

Stopped by today I’m pretty sure i was served by Ron! Lovely fella and incredibly helpful. Will return when I get my tax return.

I thoroughly enjoyed my recent visit to the store in Melbourne. When I visit the store on my previous holiday, I met Liz. She was very knowledgeable and was able to assist me in my purchase of earrings. I met William on my recent visit to make a purchase of a ring and several pendants. He was very professional and knowledgeable. We spent some time in making the decisions based on the selection of light opals. It was very difficult to make a decision but with his help I was able to. I would highly recommend anyone who is interested in purchasing opals to shop here. I will definitely purchase all my opal jewelry from The National Opal Collection.

The National Opal Collection place is a really well presented retail outlet of Australian Opals. However: The opal necklace I was interested in was priced at $180, a fair price I thought. After making the purchase decision, I was informed by the sales woman that the chain attached to the opal was not a "sterling silver" (?) chain, but something of lesser quality. She then upsold me on paying another $30 for a "better" chain.... and.... kept the replaced chain.. The experience gave me a feeling that I was taken advantage of. Why not in the first place attach the opal to a good quality chain ?

Came in to buy something for my beautiful girlfriend. Will was extremely helpful, humbly walking me through all my options and providing key insight and recommendations throughout the whole process. Each piece was as stunning as the last, with some amazingly curated and crafted opals which absolutely blew me away with their depth and intricacy. I found the perfect piece and quickly snapped it up. My girlfriend loved it. Can't thank NOC enough for their help. 10/10 customer service and 11/10 opals. Can't recommend them highly enough.

Great place one should not miss to explore when visiting Melbourne! Fascinating exhibits and super-friendly staff. I found a wonderful birthday present for my daughter and could broaden my horizon by the explanations I got for the samples. Definitely a highlight of my stay in the city.

Friendly, knowledge, helpful, staff, Huge variety of beautiful quality opals. Excellent museum display and opal information. Great shopping experience. ❤️
