Read More >I received my opal this morning since it was delivered to my office yesterday and I was off. I had it sent here because there is always someone to sign for packages. The opal is absolutely beautiful. I love the many colors and how they dance in the light. I am going to bring it to my jeweler over the weekend to have it set as a pendant. It was a pleasure doing business with you.
Thank you again
Package received, and these are gorgeous – exactly what I was hoping for. Thank you!
It is almost a year since we bought a beautiful opal ring from you. Back in The UK I get a lot of comments on the unusual colour and iridescence. May your business go from strength to strength in the future.
I’m so incredibly estatic I can barely contain it. My gorgeous ring arrived via registered post this morning. Thank you from the bottom of my heart for this fantastic piece of jewelry. It feels like I’m wearing all of the colours of October on my finger. It’s got the deep reds, firey oranges, and bright yellows of the turning leaves, with the warmth of grass green. It also has the dusky shades of purple and deep blue which are October’s twilight colours. The security of the bezel setting and the durability of the Boulder Opal mean that I will now wear my birthstone daily. Please tell the jeweller that he/she did a marvelous job on the ring. It fits wonderfully with my wedding band, and the two rings look like they were made to go together on my finger. I’m in awe that this was managed without your ever having seen my wedding band. It is wonderful to see the myriad of colours that comprise my favourite season framed in such a beautiful ring. Opals Down Under has done it again. You have gone above and beyond my hopes and expectations, and delivered perfection. I will continue to sing your praises to all and sundry. Your customer service is among the best of any establishment I’ve patronised. Your value for money is also unparalled. Thank you so much, again.
Pendant has arrived and the colours really stand out, fantastic.
Rhys – just got the ring. It is spectacular. Thanks so much for your work, and for being flexible on the stone! I love it.
I just wanted to email and say a huge ‘Thank You!’ for your excellent customer service and prompt delivery. I ordered yesterday afternoon and received the ear-rings this morning. We are ecstatic with the purchase and sure our departing colleague will love them as much as we do! I would not hesitate in recommending Opals Down Under to anyone. Thanks heaps!
Got the pendant – its great – Thanks!
Ring arrived this morning and looks awesome, thank you. My wife to be is going to love it.
The pendant received today. It looks great – exactly as advertised.
