You Can't Find Better

I was shopping around different place to find a ring and I came along the "The Book of Diamond Knowledge" on their site. I really enjoyed the read so I figured I had to go in and check them out. I felt a little weird that they had a 5/5 rating, but after I went through the process, I understand it is totally accurate. They found me the perfect diamond for my budget. Everyone loves my fiance's ring. Tim and Randy listened to what I wanted and gave me great suggestions to make a perfect ring. Being able to design your own ring setting for the same price as buying a "mass-produced jewerly store chain" setting is also a huge plus. Your fiance will love it even more because it is one of a kind. Before I started I didn't know anything about diamonds. Now I feel very confident with future diamond purchases. Give them a call...you have nothing to lose.

Easiest decision I've ever made!

I live in Atlanta, GA, and I have spent numerous months researching diamond prices and speaking with salesmen to get something amazing within my budget. Needless to say, it has been very difficult and I was close to settling for something that I wasn't 100% happy with. I heard about Randy and Diamond Vault of Troy from a family friend who is also in the diamond business. He was very highly recommended from someone who had a lot of experience in this field so I decided to give him a call. After my first conversation with Randy, I was convinced that I would need to look no further. He treated me like we had been friends for years and I could honestly tell that he really wanted to get me the best diamond for my money. Within only a week, Randy had found the exact diamond that I had been looking for and it was under my budget! I also did not have to worry about going to 3 different places to get the stone, setting, band, etc. Like I said, easiest decision I've ever made. I will definitely be passing on the recommendation for Randy Cole and Diamond Vault of Troy!

Amazing service, Amazing Company! If you are looking for a jeweler that you can trust I strongly recommend these guys! They were honest and up front with me in appraising my brothers ex fiances egagement set. While I sat there they offered me refreshments, wine, coffee, water, whatever I wanted. Then they appraised the stone and gave me an education on the diamond. They offered my brother an amount that was above anything else that he had been offered. They were professional, kind and very pleasant to work with. I will be going to them for any of my jewelery needs in the future!!!

Amazing!

I love going to the Diamond Vault of Troy! Besides the fact that I get an amazing hot chocolate blend of my choice with whipped cream to sip on while I wait for them to polish my rings, their work is like a breath of fresh air! There is no other Diamond place I would step into or trust with my Wedding ring. I feel at home and comforted as soon as I walk in the vault, knowing the men working their have my best interest in mind. At the Diamond Vault of Troy I found that this business has class, elegance, amazing work and tasty treats:)... Oh honey... when are we going to stop by the Diamondy Vault again? :-D

Diamond Vault of Troy - Like shopping in Somerset South

Diamond Vault of Troy is located in the Huntington Building on the 2nd floor. You have to push a call button to be let in.



When you are let in you will be greeted with a smile from professionally dressed people who genuinely want to help make your wants, ideas, hopes and wishes become reality, that are experts in this busniess. They are motivated to come to work each day to make others happy and it shows. And, they know what they are talking about. You will be offered a beverage of your choice, and the atmosphere is very welcoming, comfortable, and positive.



Most of the time when you go to a jewelry store, it is exciting and fun, and that is easy and fun to work with those customers (which there was a steady stream in the ~ 2 hrs I was there, and each customer was treaed the same way and was very happy). Personally, I was there for a sad reason, but I was treated with sensitivity, pateince and kindness. I felt like I was talking with family.



So, whatever your jewelry need, I recommend Diamond Vault of Troy. You'll get good, genuine, professional service, and feel at home. They will go above and beyond your expectation for standard service.



Thank you, again, Diamond Vault, for ALL you did for me!

The Diamond Vault did a fantastic job on my wedding ring and my fiancees. Once we saw the final product we had her engagement ring redone by them and it looked better than when I originally got it. The custom work that they do is tremendous. All you need to do is describe what you want and they'll create it.



I would highly recommend them to anyone and everyone. They were all so nice and knowledgable that I will be going to them for all of my jewlery needs for a lifetime

I'll never go anywhere else!!

Randy is the best salesmen I've ever met. He is completely dedicated to the satisfaction of his customers. My sisters and I wanted these custom "sister rings" made within a week, and Randy was able to knock it out for us and at a reasonable price! He is completely dedicated to his work and truly values client feedback. Seriously... if you want a beautiful unique piece of jewelery see Randy or anyone at Diamond Vault of Troy! They will provide the best customer service, you won't regret your decision to go there.

My husband is extremely detail oriented and cost conscious. Tim and Randy exceeded his (and my) expectations with my custom engagement ring and wedding band. After being married three years and having a baby, we went back to Tim and Randy to re-size my rings. They are honest and efficient, a great combination. They are our jewelers for life.

I had no idea what a position an engagement ring put the guy into. Randy at Tim at Diamond Vault helped out my fiance at ease and helped him to create a beautiful custom ring for me. The ring could not have been more perfect! We went back to get our wedding bands from them as well. What a help they both were! I look forward to many more years of diamonds from them!

Diamonds and Wine

There are two things I love Diamonds and Wine. Well the Diamond Vault in Troy has both. One on one consultation, along with great price, customer service in a relaxing setting with a glass of wine. What more can you ask for? I took some gold that was very special and Tim and Randy gave me an awesome price. We also got our wedding bands, mine custom fitted to my engagement ring. I would reccomend the Diamond Vault to anyone.



Very satisfied customer,

Can't find better service or quality anywhere

I have been all over the world and dealt with different jewelers, and I have NEVER found the quality or service they offer at Diamond Vault of Troy. They want you to be a satisfied customer and become their fan, and they put muscle behind that. Every time I've gone in they have offered me something to drink, and cleaned my jewelry. They have fixed little things w/o charge, even things I had purchased prior to enjoining them as my jeweler. They have told me when I asked for special things that other people told me I couldn't do, "there isn't ANYTHING you can't do!" and made molds and did special things...



You can't find more amazing service or quality anywhere. I tell EVERYONE about Diamond Vault of Troy.



I have purchased quality gifts from them, from cufflinks, to a wonderful clock for a wedding gift. Diamond Vault is that special jeweler where you can have someone you trust take care of all your jewelry and special gift needs for a lifetime.

Amazing!

Diamond Vault of Troy really did and continues to do an amazing job! My wife and I are really pleased with everything they have done for us. They are 1st class individuals who know what they are talking about. I would recommend them to anyone looking for jewelry. I even got my mother-in-law to come in because she was stunned at their work! Come to these guys if you want the real deal!

Above and Beyond!!!

By far these guys are the best out there! During my recent visit to the Diamond Vault I was so very impressed with Timothy and Randall. Their expertise, knowledge and overall experience was outstanding. I don't usually write reviews, and here I am writing one to pass the good word on! I've sold my gold over the last year to various places, however after being referred to Timothy and Randall by a friend they have given me the best price by far for the gold I brought in. I wish I would have come to them sooner. Also having a few collectible items (presidential memorabilia and coins) not sure where to go with them, they were quick to take a look, research it, (give me a little history lesson) and where to go with them. After leaving, I too was so very satisfied as a lot of other people I can see, I can't wait to go back! I look forward to having them design a ring for me. Take the time, they're worth the drive!!!!!!!!!

Awesome!

I had a bunch of miscellaneous gold jewelry to sell. I wanted a reputable place to sell it. I was skeptical of the pop-up gold businesses and gold parties you hear about. I wanted a trustworthy broker. Well, I found that with The Diamond Vault and Randall Cole! They made the process simple, straightforward, honest and I walked away VERY satisfied customer!

Great Experience

I have never really liked shopping for jewelry just because I don’t know anything about it. But Randy over at the Diamond Vault made my experience a dream. I not only got a great deal but I also learned ALOT about diamonds with there colors and clarities. I sort of feel like an expert now. I highly recommend them for anything jewelry related.

Great Service!

I needed a present for my Moms birthday and Tim at Diamond Vault took care of me. He found a pair of earrings in my budget and made sure they were shipped with a hand written note and on time for her birthday. She loved them!

I would highly recommend them, not only for their great jewelry, but for the amazing service.

More Than Trustworthy

I bought a big beautiful diamond ring from the Diamond Vault. It was placed into a custome setting. Randy and Tim sat down with me and gave me their undivided attention. They listened to what I said I wanted and delivered, big time. They gave me a deal that no other place could match. They gained my trust and my confidence for any jewlery purchase I make in the future. ...Did I mention, my fiance LOVED the ring. Haven't seen another like it. THANKS!!



Your very satisfied customer,

Best Experience Ever

What impressed me so much about The Diamond Vault of Troy is that I didn't walk into a room with a bunch of display cases which would have probably overwhelmed me. The very professional and unique approach that they take of sitting with you to find out what you have in mind or what you are looking for before they take you into the vault is perfect.



Tim and Randy are both so personable and make you feel like family from the moment you walk in. We got all of the attention we needed without the distraction of other people around.



I have already recommended The Diamond Vault of Troy to friends and family and will continue to do so. I'm a customer for life.

Your the best

My Husband is in the Navy and we eloped almost 5 years ago. We decided we would save money and order a set of custom rings when the time was right. So I spend 3 years looking at settings and stones and attempting to find the right Jeweler. I grew up in the Detroit area and was given a recommendation to work with the Diamond Vault of Troy. I am a perfectionist and I couldn’t be more pleased with the work that was done for me. I emailed photos and a detailed description of what I wanted to the owner and within a week I received and email back with my design. I made a few adjustments and they sent me new photos with the changes and within a month I had exactly what I had wanted. The quality of the workmanship is impeccable. I knew I had something special when my husband and I took a trip to the Providence Place mall and strolled into Tiffany’s and the sales lady commented on how amazing my ring was. I would recommend the Dimaond Vault of Troy to anyone anywhere they were so easy to work with through email and via phone. They listened to what I wanted and followed through. My husband and I are very particular about how we want things done. So Thank You again Mr. Cole for your hard work.

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.
