A photo from a customer review featuring a 1.49-carat Montana sapphire

We had such a positive experience with Earth’s Treasury, Jeff, and choosing the stone of my dreams!!! When I first saw a “Montana Sapphire,” I knew I wanted one for my engagement ring. After seeing the gorgeous array of stones available at Earth’s Treasury, I knew it’s where we wanted to purchase. We were a bit nervous about purchasing over the internet, but with the videos we were presented it was easy to choose and when we received the stone and saw it in person – it was beyond beautiful! Knowing we had the opportunity to trade for a different stone if we needed to eased our minds as well. If you’re looking for a unique stone – Earth’s Treasury is the place!

A photo from a customer review featuring a custom two-tone engagement ring and bracelet

I had the pleasure of working with many members of the staff of Earth’s Treasury for my custom engagement/commitment ring and commitment bracelet. The process started with selecting the stone for my engagement ring. I was looking for a parti-color blue/orange sapphire as I wanted a stone that represented fire and ice. Jeff sent me videos of the different blue/orange Montana sapphires that I had selected on the website. The gems were beautiful but didn’t quite fit the look I was going for. Learning from Jeff that the blue-orange combo is quite rare, I was about to change my vision to a two-stone theme. But below and behold, I was emailed the day before my birthday about a blue/orange Montana sapphire that had just come in and the staff wanted to know if I wanted to proceed with it for my engagement ring. It was a very quick “yes” from me and I was put in touch with Nina from the shipping department who had the sapphire sent out to me so I could see it in person before making my final decision. The sapphire was perfect for me and then I was directed to Lauryn, the head of the jewelry design team to start creating my custom ring. The entire custom design process was a lot of fun from start to finish. Based on my vision, timeline and budget, Lauryn put me in touch with their Senior Jewelry designer, Julia. I had A LOT of ideas for my engagement/commitment ring (too many honestly) and Julia gave the best suggestion of taking elements I had listed in my ring design and having a second, complimentary piece of jewelry created. In the end, I opted to have an asymmetrical fire/ice ring made with orange accent sapphires on one side to bring out the orange in the main blue/orange sapphire; the other side represented wings from a bird (a goose in my case). For my custom commitment bracelet, I chose a claddagh bracelet that had two geese (instead of two hands) holding the center heart with accent blue sapphires around the entire bracelet as well orange color-treated diamonds in the crown to tie in with the engagement ring. We even added some Greek holloware inspiration as I wanted to fuse my Irish heritage with my future husband’s Greek heritage into the design of the bracelet. For both jewelry items, Julia was in touch with me throughout the entire process which involved sketches, inspiration ideas, and CAD renderings, as well as 3D printed versions mailed out to me to check out the fit. In the end, I ended up with two BEAUTIFUL custom jewelry items. My partner proposed with the ring a couple months after we received it (I didn’t look at in person until the proposal so the real-life version was a surprise) and I wear my claddagh bracelet with it in the “engaged” orientation and can’t wait to wear it soon in the “married” orientation. Thank you everyone at Earth’s Treasury! I am head over heels for my custom jewelry items and couldn’t recommend this company enough!

I just wanted to express my heartfelt thanks for the incredible service during my engagement ring exchange. Your hassle-free process and attentive online support made everything so smooth. I’m absolutely in love with my new ring! Here are a few snapshots I’ve made with my iPhone. No camera can do justice to it! 🙂


The "Isolde" ring in platinum with 1.51-carat Montana sapphire

I have purchased two rings through Earth’s Treasury, and both experiences were exceptional. The rings in person exactly match the pictures, so if you love the design on the website, you will love the design in person. It was my first time purchasing more custom jewelry, and they made it very approachable. At different ranges of the process I interacted with about four different team members, and each one was very helpful, knowledgeable, and responsive. Selecting the stones was probably the most daunting part, but Earth’s Treasury did two really helpful things: 1) Once you have narrowed it down to 5-10 stones, they will take additional pictures and videos of the stones in several different lighting environments. These can also be side by side for direct comparisons between stones. 2) Once I had selected and purchased the stone, they mailed it to me so that I could inspect it in person to ensure it was perfect. They do this ahead of any physical work on the ring so that if you don’t love the stone, you can swap it out without any issue. Honestly, it all ended up a pretty fun process and I’m looking forward to future occasions to use Earth’s Treasury.

Huge thanks to everyone on the Earth’s treasury team! They were incredibly responsive, knowledgeable and collaborative in building out the perfect ring for my fiancée. Couldn’t recommend them more!

We worked with Lauryn and Julia on custom rings. They were kind and patient as we worked through the design process. We received our rings today and absolutely love them. The craftsmanship is top notch and they’re exactly what we wanted. I would absolutely do business again with Earth’s Treasury.


I had a wonderful experience purchasing a Montana sapphire from Earth’s Treasury. They have a far wider selection of gems than other vendors I considered. I had actually purchased a gem from another jeweler, and I returned it when I discovered the options available at Earth’s Treasury. They also have excellent customer service. Jeff is very responsive with all communications. I really appreciated the videos they sent me of various stones in different light so I could select the perfect item. Would very highly recommend Earth’s Treasury! I will definitely be returning for future purchases.

I want to thank Jeffrey and everyone at the earth treasury team for making my engagement ring dreams a reality!! The ring is beyond perfect and I am so incredibly happy!! They were there for me and my fiancé every step of the way!! If you were on the fence about ordering online and not a jeweler you will not be disappointed!! Couldn’t have asked for a better experience!


Found this store through the Reddit community. Learned about sapphires through their various resources online. Ordered and received a beautiful gem in the mail 3 days later (fast!!) with documentation. Will come back to shop again.


Love my stud earrings! I asked multiple questions and every question was answered in details by Jeff. Great customer service too!


A photo from a customer review featuring a ring not made by Earth's Treasury featuring a 1.75-Carat Montana sapphire

Born and raised in Montana, I was on the hunt for the perfect purple MT sapphire for my engagement ring. I was referred to Earth’s Treasury by 2 separate jewelers so I diligently stalked their website for months and asked for videos of MANY different Montana sapphires that Jeff and his team always sent very quickly. After deciding on a stone, the ordering process was easy and their communication with arranging shipping for when I would be available to sign for the package was a breeze. The stone I ordered, while beautiful, was not quite the color I was hoping for–but I was able to exchange it for a different stone. The exchange process was very easy and I’m happy to report the 2nd stone I ordered was the one! I absolutely love the ring i was able to create with it 🤩


The "Ilana" ring in 14k yellow gold with 1.45-carat Australian sapphire

I bought two rings from Earth’s Treasury. They are both gorgeous! The stones are beautifully cut and the metalwork is excellent.


Incredible quality of stones, super customer service, great communication upon my needs and ease of dealing with staff. I have been following the company for a long time and will continue to do business with them.


The "Holly" ring in 14k rose gold with a 0.84-carat Montana sapphire

I couldn’t recommend this company highly enough. The pricing is fair, the customization process is easy, and they frequently follow up on both the status of your order and exactly what qualities you are prioritizing. I was a bit worried about ordering a gem online, but they even sent me videos of the actual gem to see how it looks in natural light! I will definitely buy from them again in the future.

Can’t recommend these jewelers enough! My partner and I found Earth’s Treasury when we were looking to design a one of a kind sapphire engagement ring. Their selection of gems and ring designs was impressive to say the least, and they also do a great job of providing the origin of their materials. The website was sleek and easily to use. When we contacted them about some unique requests, they invited us to their charming workshop In Pennsylvania, made 3D renderings of the designs we requested, and gave us the grand tour as well! Not only were they able to accommodate every one of our requests, they did so quickly and without charging us any extra fees! The ring, once ordered, arrived within a month, and is now resting happily on my fiancée’s finger. It was so much more beautiful in person than either of us imagined!


I was having a hard time finding a sapphire for an engagement ring, but when I found Earth’s Treasury everything became easy, even fun. There were lots of options that were easy to search and evaluate. When I made requests to see videos comparing options, I received responses quickly. This helped me make my decision with the best information possible. Delivery was painless and the stone was well-packaged. They even suggested a better location to which to deliver it. Would use again for any future stone shopping.

Fantastic job from Jeff and his team designing and building a custom engagement ring. I couldn’t be happier with how it turned out.


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

I was very happy with my experience. Jeff was super helpful as I made my decision and is a fun gem nerd to talk with. Just got my ring back from my local jeweler (I replaced a scratched stone with my sapphire in an existing ring) and am thrilled.


The "Holly" ring in 18k yellow gold with a 2.07-carat Montana sapphire

All I can say is that Jeff and the rest of the folks at Earth’s Treasury have made buying an engagement ring an extremely smooth process. My specific requests were fielded and Jeff helped me decide on the perfect center stone after some weeks going back and forth. Kudos to you all for being so professional and personal!


The "Evelyn" ring in 18k yellow gold with a 1.65-carat Montana sapphire

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.

A photo from a customer review featuring a custom ring in platinum with a 2.59-carat Australian sapphire

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.
