The ring buying process was a great experience. The timeline estimate they gave was exactly on time and the resulting ring was beautiful. Highly recommend Earth’s Treasury.

Had a fantastic experience from start to finish. Professional service and very reasonable prices. Most importantly, my wife loves her ring!

Working with Julia to design a ring was a top-to-bottom custom experience. She and the rest of the Earth’s Treasury team are incredibly knowledgeable and creative, making this initially daunting prospect straightforward. From choosing the gem, to designing a setting, to receiving the finished product, the process was fun and efficient. Gemstones for an engagement ring can be intimidating given the ubiquity of diamonds in the market. However, the selection at Earth’s treasury is vast and Jeff’s talent in cutting gems sets them apart from other available options. Ellen and I initially chose a different gem, and because Earth’s Treasury sends you the stone to view in person, we came to the conclusion that it didn’t fit our vision exactly. We were able to exchange the stone and the process was remarkably simple and we never felt rushed or pressured throughout. This meant that in the end, we found a stone that we believe is a perfect fit. Ellen has had the ring for a few days now and we’re still fascinated with all the new colors we are discovering in different lighting. ET gems are dynamic and timeless. Thank you guys!!


If you are anywhere near the home office of Earth’s Treasury, do yourself a favor and make an appointment to see their fantastic array of gems. It is an experience quite unlike the garish lighting and undereducated sales representatives at a mall jewelry store. You can meet the gem cutter and discuss your needs and wants. You can see the gems that you choose, on your own hand, and in any light imaginable. And if you think that makes little difference, I am here to tell you that you are quite mistaken. The patience, care and a service at Earth’s Treasury are unmatched in my experience. I chose a sapphire-that changes from a dark London blue topaz color to a teal color to a hunter green color depending on the light. It is so deliciously distracting! I will treasure this ring for the rest of my life. My husband loves my reactions to it. Everyone I show it to is wowed. It is EXTRAORDINARY! I also had my eye on an unheated Tanzanite. My husband spoiled me by buying it too. This stone is kind of large and more fragile than is practical for a ring. So I will enjoy having a pendant designed for it. In summary, have your favorite gems mailed for your inspection, or, if you can possibly get there, go look at them at their office. You will be enthralled by their exacting workmanship, knowledge, inventory and service. Thank you, Jeff and Julia! I couldn’t be happier with our purchases.

So impressed. We ordered my engagement ring and wedding band together and they fit together like a glove. I chose two different styles for my rings and they made them fit together beautifully. They let me choose a sapphire for my wedding band in a color that I think makes the engagement stone pop even more. All of the stones are stunning and have so much sparkle. The main sapphire is such a gorgeous, dynamic color that changes in different light and sometimes almost has a glowing quality. The cut is so unique and everything about the rings is so high quality and artful. The rings seem very strong and durable and yet are so delicate in appearance. On top of everything else all the customer service has been top notch. Every single person I spoke with was kind, friendly, and patient. I would very highly recommend this company to anyone wanting a sapphire, a unique ring or stone, or just gorgeous high quality jewelry in general. I can’t even imagine a more perfect ring set for me and I’m so grateful to have found Earth’s Treasury and that I got my dream rings!

Earth’s Treasury has a beautiful choice of Montana sapphires which is what I wanted for my engagement ring. The owner Jeff and team went above and beyond to help us pick out my perfect teal Montana sapphire gemstone and design the setting. We also worked with the Earth’s Treasury to design my wedding band. They were able to send me renderings of both rings put together and also sent 3D prototypes so I could get a feel for bands and settings. They were super patient and helpful and I would use them for my next ring update and recommend them to anyone looking for a special occasion ring.

I worked with Julia on a fantastic engagement ring. Initially I was struggling to bring my idea to paper, but she did a fantastic job converting one of their current designs into something more of what I had in mind. I am very satisfied with Earth’s Treasury’s work, their responses, and creative design. Julia in particular was fantastic.

I went through the process of getting an engagement ring with Earth’s Treasury. From the start, they had an awesome selection of sapphires and responsive support team. Their customer service team is top tier (shout out Tessa, Lauryn, and Jeff). They were super responsive, fast, and answered any questions I had throughout the whole process. They offered plenty of insight as to how the ring is made, provided updates on the creation of the ring, and even took the time to create virtual renderings of multiple possible rings so I could get a good look at what the final product would look like. In the end, the final product looked even better than the renderings, and blew me, and my now fiancée, away. To anyone looking to get an engagement ring made fully online, I would absolutely recommend Earth’s Treasury.


The "Fiona" ring in 18k yellow gold with a 1.80-carat Umba sapphire alongside the "Fiona" band in 18k yellow gold

My 1.8 Umba sapphire in the Fiona setting just arrived and it was perfect! Very easy to craft on their site. When it arrived it was very nicely packaged. The Earths treasury team were in contact the entire time. We went with Earths treasury because we felt that they would provide the type of quality and honesty that big box stores seem to have forgotten. We were not disappointed with that decision and now we can be confident that what we purchased is what we got! Good luck Earths Treasury Team and I hope you guys do great.


Thank you, Jeff, Tessa, Nina, Lauryn, & Ollie for making the process of choosing and creating my partner’s engagement ring such a wonderful experience. We would highly recommend Earth’s Treasury to anyone looking for a unique ring – engagement or otherwise. We honestly could not speak more highly of the entire Earth’s Treasury team, they were so helpful, kind and thoughtful. They made this process so personable and positive, it was an absolute pleasure. And about the ring, what can we say? It’s stunning and more perfect than words could express. I was able to propose at the Botanical Gardens in Rio De Janeiro to the love of my life with a ring that symbolized all of our love and it was truly magical. Thank you, thank you, thank you!

Cheers, Arielle & Emma

A ring not made by Earth's Treasury featuring a 1.11-Carat Montana sapphire

The staff were so helpful and friendly. They responded immediately to all my inquiries. The return policy is forgiving and quick. I even took the stone I finally settled on to a geologist and they were surprised how good the quality was for the price. I would highly recommend this place if you want a stone!


Jeff and the team at Earth’s Treasury were extremely helpful in finding the perfect sapphire for my ring. I shopped around at more than one location for a specific color I was looking for. Jeff was very open and shared his extensive knowledge in gemstones with me. This helped tremendously weeding out the different stones I was presented elsewhere. Ultimately after everywhere I looked it was evident that Earth’s Treasury had the best quality and selection of gemstones (and service, too). I highly recommend using Earth’s Treasury. Being states away from their location did not hinder the experience at all.

Jeff and his team at Earth’s Treasury are the best. I would recommend them to anyone hoping to find (or design) a unique, custom ring, including first-timers who have no knowledge of the process. They worked with me to create a custom engagement ring and the whole experience couldn’t have been better. Jeff was attentive, patient and helpful during the stone-selection process. I never felt rushed or stressed while picking out a stone, and when I decided on an option, I felt confident about my choice. Hyungji designed a custom band and similarly, she was super helpful and communicative throughout the process. I went into this process without any knowledge of rings or stones, and came out of it with a beautiful ring that I love. I wish there were more reasons to buy special jewelry like this, because I would love to work with this team again! Thanks!

Working with Earth’s Treasury to create my fiancée’s engagement ring was absolutely the best decision I could have made! The entire process— from discussing an initial design, to choosing a gem and getting to actually see it before purchasing, to finalizing the ring— was seamless. Communication was excellent, and even if I didn’t always know the exact terms for something I wanted or didn’t want, Julia was able to help me! My fiancée adores her ring, and I feel proud that I was able to have a hand in designing something unique and especially for her. I’m immensely grateful for Julia’s eye, advice, and skill in designing her dream ring. Thank you, thank you, thank you!


The "Aislinn" ring in 18k white gold with 3.12-Carat Montana Sapphire

I ordered two Montana Sapphire rings and they both turned out absolutely gorgeous!! Jeff and Nina were so incredibly helpful and patient. I am in love with my new jewelry, thank you so much!


The "Vanessa" ring in 14k rose gold with a 1.37-carat Montana sapphire

Wonderful place. Jeff & his team did such a great job from start to finish – very responsive, professional and thoughtful. Jeff was fantastic explaining the process of how the rings are sourced and made; and we appreciated his honesty with how rings will show in different lighting conditions; his descriptions of the rings; and the values they hold over time. We also appreciated their willingness to work within our budget, and offering a military discount was very kind of them. We were impressed with all the tools his shop uses to craft their products and we’re so glad we found them for my engagement ring. They were able to get my ring made well before my engagement party. I absolutely love it.

Great experience in choosing a sapphire. Lots of support in exploring options for and designing a setting. Informative staff and great communication throughout, very clear and timely. The finished product is exceptional. Strongly recommend this company for both their highest quality product and professionalism. They will be my first stop for future gemstone purchases.


The “Laurel” Ring in 14k yellow gold with 2.10-Carat Montana Sapphire, alongside The "Melisani" band in 14k yellow gold

The team at Earth’s Treasury is amazing! I can’t express enough how smooth and also fun the process was for creating my dream engagement ring and wedding band. I was provided quick turnaround of CAD renderings, and many options for gemstones to choose from in different lighting, so I could have an accurate idea of them. I will definitely be creating more jewelry with the team in the future!


Jeff and his team at Earth’s Treasury are incredible! They helped me select the perfect stone around which to build my fiancee’s ring. By purchasing multiple and having them FedEx’d to me, I was able to spend time comparing them in different light before sending back the rest. Their prices are extremely fair, and they have by far the biggest selection of any source I have found. A+ service and experience!


Premium 6.0mm Montana Sapphire Earrings (Heated)

Bought my wife Montana sapphire earrings for her birthday from Earth’s Treasury and she absolutely loved them. Perfect size and beautiful cut and coloration on the sapphires. Jeff is very responsive and a pleasure to business with. I highly recommend Earth’s Treasury and will be buying from them in the future.

Earth’s Treasury went above and beyond to ensure our ring was perfect. Their expert team helped guide us every step of the way from choosing a perfect stone to fitting it in the best possible setting. Our experience from start to finish was nothing short of incredible and we can’t recommend them enough.


The "Cathedral" ring in 14k white gold with 1.17-Carat Montana Sapphire

Beautiful Montana sapphire and excellent quality and workmanship on the engagement ring. Jeff and Nina were very quick to respond and helpful. They followed up after the sale to make sure I was happy with the ring. My fiancee (she said yes!) absolutely loved it! We both do! We’ll be getting our wedding bands from Earth’s Treasury in the near future.


The "Fern" ring in 14k rose gold with a 1.55-carat Montana sapphire

The entire team at Earth’s Treasury was absolutely amazing. After a consultation and me showing Pinterest inspirations, they were able to successfully curate a sapphire ring that exceeded all expectations and was even more beautiful in person.


A photo from a customer review, featuring The "Milos" Ring in 14k yellow gold with 1.02-Carat Montana Sapphire

We had a wonderful experience working with Jeff and Lauryn to design our custom engagement ring! It turned out better than I could’ve hoped for. The whole process was so smooth- from receiving several videos to pick out the stone, to coordinating the timing of creating the ring, to actually designing and tweaking the ring. Communication was always prompt, patient, and helpful. It’s also great that they will be able to make the wedding ring when we are ready! I️ would recommend them 100 times over.
