Calderagem Avis 11

To celebrate our tenth anniversary together, I wanted to gift something truly special and unique. I initially thought of getting an aquamarine ring and discovered Caldera Gem during my search. After considering the options and some advice from Caldera Gem, we chose a beautiful topaz instead, which is truly beautiful! I’m thrilled to now be able to create something truly memorable.

I had been thinking of buying a green sapphire for a while & I can honestly say that the customer service & the quality of the sapphire I bought are both second to none. If I could give Calderagem 6 stars I would!

Great service all round!

I purchased an absolutely beautiful peach sapphire from Caldera Gem. I still haven’t made it into anything yet but have a few ideas and just love looking at it! I couldn’t find what I wanted in any of the stores and a search online led me to their website. I was surprised to learn they were based in New Zealand but they do ship internationally and advised me that I could expect to pay VAT on arrival to the UK which I just incorporated into my budget. They sent me tons of photos of the sapphire I was interested in and told me a bit about where and how it was sourced which was nice. It took just over a week to arrive with Fedex and there was a bit of paperwork to sign but it arrived safe and sound. The packaging was really thoughtful too and it was so exciting to unbox it and find my little gem. Highly recommend this website for anyone looking for great quality and service.

After a fruitless search for the perfect yellow sapphire I finally found what I wanted at Caldera Gem. I was a bit hesitant to order something so expensive online but talking to them really put my mind at ease. They sent me all the photos and videos of the stones I asked for, as well as copies of certification and told me about their sourcing process. They also explained their return policy but honestly gave me so much info that I didn’t feel I’d need to use this and I didn’t. We did have to pay GST on arrival to Australia but this was all explained upfront and incorporated into the overall budget. Delivery with Fedex was pretty straightforward and only took a couple of days. The fact that the site is run by qualified gemmologists really clinched it for me and they made the whole process really easy. The sapphire arrived and it was just perfect.

My partner and I recently got engaged and I wanted something different. Not the standard diamond ring. I had my heart set on an emerald and stumbled across Caldera Gem on my searches. After making enquiries about an emerald on their site their gemmologist kindly explained that emerald was not the best choice for an engagement ring due to its softness but suggested the best way to have it set if my heart was set on the idea. After much deliberation we decided to opt for a green sapphire instead and I honestly couldn’t be happier with it! We are now in the design process and I am so excited to be creating something truly unique. Thanks so much Caldera Gem.

A few months ago I bought a blue sapphire from Caldera Gem and was blown away by the quality. The service was excellent and they sent me a number of additional photos and videos of the stone to help me decide on it.

I've since taken it to a jeweler to be made into a ring and he said it was really well cut and a very nice stone. He even offered to buy it from me if I ever decided to trade it in!

Highly recommend this website. It’s run by a certified Gemmologist and this really helped me feel comfortable about the purchase.

My husband and I recently renewed our vows and wanted to upgrade our rings in the process. We wanted something that wasn’t a diamond for my ring and decided to go for a green sapphire as something a bit down-to-earth, different and my favourite colour is green. Not liking any of the options in jewellery stores we decided to source our own sapphire and design our own ring with a local Jeweller. The green sapphire options at Caldera Gem were the nicest we came across and seemed to have the best green colour and appearance. We spoke to their Gemmologist who educated us on the heat treatment that the stone had received and advised us that it had been sourced in Madagascar and cut in Sri Lanka. Their service was very detailed and responsive and I found this to be reassuring. When the stone arrived it was packaged in a gorgeous wooden lidded box which was a really nice touch. We're both really thrilled with the sapphire and just wanted to say thank you so much for all your help.

Bought a green sapphire, didn't know what to expect as I didn't know the company from before, and the experience from start to finish was great. Seller answered all my questions quickly and the shipping was fast, product was great too.

I recently had the pleasure of purchasing a Colombian emerald from Caldera Gem, and I must say, I am thoroughly impressed. From the moment I sent my enquiry I was blown away by the exceptional service provided. They sent me additional photographs and videos of the gem before I committed to the purchase and also had it independently verified by a valuer in NZ for me. This put my mind at ease in parting with quite a considerable sum of money. However I am glad I did. The stone is truly exceptional and better in person than any of the photos could possibly convey. They also walked me through the customs process to have the stone delivered to me which meant that when Fedex contacted me to pay a small duty and make the delivery I was aware what needed to happen. I highly recommend Caldera Gem to anyone looking for high-quality gemstones and exceptional service.

I recently purchased a stunning loose sapphire from Caldera Gem and I couldn't be happier with my experience. It’s really beautiful. The service I received was top-notch, with the team at Caldera Gem going above and beyond to ensure that I found the perfect stone for my needs. The delivery was also prompt and efficient with Fedex, and I appreciated the beautiful wooden presentation box for my stone. I took the stone to my jeweler to verify its authenticity (even though it came with a certificate I did want to be sure and I am always a bit nervous of buying things online) and he said it was genuine and was also quite impressed with it.

I highly recommend Caldera Gem to anyone in the market for loose gemstones. Their commitment to quality, service, delivery, and communication truly sets them apart from other online retailers. Thank you, Caldera Gem, for an exceptional experience!
