Ultimate diamond professionals

I am happy to recommend the Diamond Vault of Troy to all of my relatives and friends. Timothy helped my fiancee find the perfect engagement ring and wedding band he was looking for, while staying on budget and exceeding expectations. Timothy is exceptionally accommodating, refreshingly honest, and handles client needs with confidence and care. I love my ring and would definitely go back to the Diamond Vault of Troy in the future. The quality of their diamonds plus their accommodating services sets them apart from the rest.

Great Service

I'm very happy with my Diamond Vault experience. The customer service was excellent. Tim and Randy were very friendly and knowledgeable but not pushy. The atmosphere was comfortable but not stuffy. They gave me a better price than other jewelers I visited. Also, they have beautiful jewelry. I would definitely recommend them to others.

A+ Experience!

Diamond Vault Of Troy is truly a 'diamond in the rough.' After sifting endlessly through the spurious sales tactics of the unscrupulous Manhattan jewelers, I took my buisness westward. Although the thought of a long distance buisness transaction initially made me feel unsettled, my discomfort was swiftly put to rest. Throughout the entire process of selecting a ring, I found Randy's level of professionalism to be exceptional, and his knowledge astounding. I cannot thank Diamond Vault enough, and I will continue to use them in the future, and refer them often. Keep it up DVOT!

Custom ring from a picture

Back in September/October I already had a wedding ring that I was going to give to my fiancee. I called The Diamond Vault of Troy after a recommendation from a friend. I brought in a picture of the ring that I already purchased and they made a custom one from it to match with a better quality/larger of a diamond for less price. I also went to several other places before buying the original ring and each place (including where I bought the first ring) it was very annoying when they keep pestering you to make a down payment after the fact that you let them know you are looking around and getting quotes, that does not happen here. Randall and Timothy thanks for everything! As you know I still have jewelry to be fixed from when I talked to you last time, but I am always running behind just as I was with the ring. Shelley loves the ring and I am glad she was able to meet both of you. George S and Shelley M

The BEST Service and Quality

I wanted to buy diamond earrings for my girlfriend for Christmas and went to many local stores. All the diamonds I looked at just didn’t seem to have good color or clarity. My brother recommended I go to The Diamond Vault of Troy, and I was pleasantly surprised. Not only were Randy and Tim professional and knowledgeable, the diamonds I purchased were amazing! I would highly recommend going there.

She loves it!

These guys know their stuff! I went to 3 different jewelers, and they were all almost double the price Diamond Vault of Troy gave me. My fiancee loved her ring, and I will go back here in the future. They give you such a low price because they know you will tell your friends!

Overall
Excellent experience

My now husband bought my engagement ring and wedding ring through Diamond Vault of Troy. We were both very impressed not only with the customer service, but also the amount of education they incorporated every time we spoke with them. My husband shopped around, and NO ONE could even come close to their price. I have sent all my family and friends to see Tim and Randy and everyone has had a great experience. Highly recommend.

You will be amazed!

You will be amazed when you do business with Randy & Tim at The Diamond Vault.

They are experts in their field and are so easy to work with.

They take their time with you and give you personalized, friendly service.

I haven't had the quality of service from any store-jewelry or otherwise before.

They explain everything in detail to you whether you are buying or selling.

You actually learn about the object you are selling or deciding whether to buy.

You are not just a customer here.

You feel as if you are a valued friend.

I am not overstating how great they are.

I would encourage you to try a few different jewelry stores out whether you are selling gold or looking for an engagement ring...and then see Randy and Tim.

You will never walk into any other jewelry store again.

Do yourself a favor:

Timothy and Randy at Diamond Vault of Troy made my ring buying experience easier, more informed, and less expensive than I was expecting. I didn't feel like they were trying to sell me anything I didn't want, which is important when you don't know much about buying a diamond ring in the first place. Timothy did a great job of working within my budget, helping me find ways to save money, and answering all my questions along the way. Even after I purchased the ring, I still had one pressing question about it. Timothy wasn't there when I called, but Randy, who I hadn't worked with much at all, took the time to explain in detail the answer to my question, which helped a lot. I went in with zero knowledge of what to look for, and ended up with a ring that my soon-to-be wife is obsessed with and can't stop talking about! Do yourself a favor and don't get your jewelry anywhere else.

Go see Tim!!

My husband and I were shopping around for quite some time for a new diamond. I wanted an upgrade and we had visited several different jewelers from wholesale to retail. We got a wide spectrum of prices and quality. I knew the size of stone I wanted and the quality as well. I was having a difficult time finding the quality I wanted in the stone with the price I was willing to pay. I had actually almost given up when my husband came across Tim and Diamond Vault. He actually went there by himself and was so pleased that he bought the stone without me even seeing it. He was so impressed with Tim's style and knowledge of diamonds and the casual atmosphere there. He was also very impressed with the fact that no one pushes you to purchase. He surprised me with the ring two Christmas' ago and I can't tell you how surprised and pleased I was. The stone is absolutely beautiful and the price and quality outdid every other jeweler we visited. Every time I wear the ring I get compliments. A close friend of mine always wants to try the ring on when she sees it and it and is always complimenting me on it...she always compares the brilliance of my stone to hers and says how hers hardly shines at all... I just say to her...go see Tim!!

Personal service and excellent product

Tim at the Diamond Vault of Troy provides customer service that you don't find around anymore. Asking questions, showing many different pieces and spending as much time as it takes to find that perfect purchase. We are customers for life and highly recommend Tim and Randy at the Diamond Vault of Troy.

Couldn't do any better for you if you were family. In fact I think they take care of you better than that. 100% recommendation. You will get the straight story here. I'd write more but for me that says it all.

impeccable excellent service and product!!!

There is not a day that goes by that people don't stop me to compliment me on the beauty and design of my ring... words can't describe how happy I am with the final quality of my wedding ring and engagement bands!! Tim Mayer and Randy both have a commitment to excellence and to making your ideas and dreams become reality as they work with you. They take the time to concentrate on the details and really implement what you want to see in your design. When I went to make my wedding bands for the ring, I had to change the design because I wanted something very specific in my head that I couldn't quite explain. Tim and Randy worked with me to design the 2 eternity bands and had to reconstruct my engagement band to get it perfect! The took time with me... they never rushed my decision time and now I happily flaunt my ring with pride! I highly recommend Diamond Vault for your jewelry because the impeccable service, attention to detail, and commitment to excellence... makes them the VERY best to work with!
