Highly recommend!! My fiance and I worked with Erin for my engagement ring and our wedding bands, and I couldn't be happier. She was so helpful on guiding us through our vision for what we wanted. She made this process so simple and enjoyable. We will definitely be back for anniversary updates and future pieces.

Cannot recommend enough. Dave helped my now-husband and me pick out first my engagement ring, and then our wedding bands, and I couldn't be happier. They're gorgeous and work so well together, and Dave has been exceptionally helpful.

Dave and the team at Seattle Diamonds are wonderful. This review is definitely a 5-star review with 100% positive feedback. I purchased my wife's engagement ring, both of our wedding bands, and a wedding day gift for my wife and we were completely happy with the buying process, their service, and our jewelry! These are big purchases and Dave and his team made it an easy and enjoyable process, and the jewelry exceeded our expectations. I have referred several clients to Dave and they have all been happy with their experiences as well. If you are in the market for jewelry I highly recommend

Hands down the best jewelry buying experience!! My husband bought my engagement ring from Dave. He didn't know a lot about diamonds at the time and Dave was friendly and extremely knowledgeable. I was completely surprised with a beautiful ring I love! Since then, we've gotten all of our jewelry from Seattle Diamonds and will continue to do so.

Dave Hall and the entire Seattle Diamonds team made the whole engagement ring shopping experience incredibly easy and simple. I went into this not knowing anything and really had no direction. Dave's expert advise and service made me feel really good about the entire experience. Dave did not try and sell me, but rather provided excellent service,advice, and education about the entire process. My fiance is in love with the ring that Dave and I picked out and I will always refer people in the Seattle area to Seattle Diamonds.

My reviews are usually hard earned and brief, however, in this case I make an exception. This place should be your last stop in your search for the perfect diamond/wedding ring. Dave is an expert in the field and he and Kelsey took plenty of time to educate us and then listen to discover exactly what we wanted. They evoked such a sense of trust from us that we knew we were in good hands. They were confident they could work within our financial parameters and ultimately rewarded us with a ring set far exceeding our expectations and at the same time appraising for way more than our purchase price

I was in the market for an engagement ring and the team at Seattle Diamonds was extremely accommodating. They made me feel comfortable making a decision about something I knew very little about by educating me, sharing their insight from 30+ years of experience selling jewelry and gemstones, and working well within my budget. They even factored in the tax when pricing things out to make sure it was truly not pushing my budget outside of my comfort zone. I didn't for a moment feel rushed or like just another transaction.
Next time I'm in the market for any jewelry, I know where I will

Seattle Diamonds is a great place to do business with. I live overseas and knew that I wanted to buy an engagement ring for my girlfriend 6 months in advance. So I emailed Seattle Diamonds to inquire about a ring for my girlfriend on their website. Erin wrote me back right away and for the remaining 6 months before my visit to Seattle she answered all of my questions in a professional and prompt way. Because I wasn't 100% sure if my girlfriend would like the ring I chose for her, I was able to pay in cash, in case I needed to get a refund or exchange. After I proposed it turned out that the

I had the pleasure of working with Dave Hall. From the beginning, he was extremely professional and upfront about the whole process. He made to sure to listen to everything I was asking and help me to find the best solution. I feel like I landed on a gold mine by buying my engagement ring from him, because the quality is superb and the customer service is top notch. My fiance LOVED her ring...it sparkles so much too! Highly recommend!!

In my quest for an engagement ring, I visited multiple other jewelers and spent hours looking online at all of the diamond websites. Not until I found Seattle Diamonds did I really feel "good" about the whole process. For my appointment, they greeted me with a hot cup of tea and took the time to review all of my needs. They found an Amazing diamond and had a ring custom made with a band they helped me pick out. To say the ring is stunning would be an understatement. From start to finish, the process was pleasant, professional, and they kept me informed every step of the way. Highly recommended

Dave Hall has been our jeweler for the past 11 years and never disappoints. Dave and his colleagues at Seattle Diamonds stand behind their product and customers. The expertise and knowledge they bring to the table is unprecedented. My wife is always happy to see the little mahogany box! Definitely go visit Seattle Diamonds if you want top notch products with Nordstrom-style customer service. It is always so refreshing to have someone that cares helping you out with large ticket purchases.

Nothing short of amazing was my experience in search of the perfect engagement ring. My journey in trying to find this flawless diamond encompassed 2 countries, 5 states, and 43 stores. Needless to say, I was a bit exhaustive in finding the perfect fit. Dave was absolutely amazing. During this endeavor I was fed many sales lines and false information by the other vendors. Dave was the only one who was truly straight forward with me. At no time did I felt like he was trying to upsale or diseave me. Dave guided me with the right information and helped me to find a ring that left my fiancĂ

Dave and his staff are amazing at many things. Their customer service is second to none . The jewelry they make is also top shelf.

Went back today to have my wife's wedding set repair and after 12 years we were treated like old friends .

Highly recommend Seattle Diamond when your looking for custom jewelry

Gentlemen:
If you are like me you are looking for a rock and once you have proposed your fiancee will help design the ring.

THIS IS THE PLACE TO BUY A DIAMOND.

The amount and quality of diamonds found here are unreal. The only other place you will find prices even close to Seattle Diamonds on loose diamonds is Costco or Blue Nile, but you wont get the customer service, the ability to see and feel and touch the diamond and talk your way through your purchase with a diamond professional.

Just received our appraisal from ring and wedding band back from 3rd party and it wasn't quite double

It's been awhile since I got my engagement and wedding bands from Seattle Diamonds, but I can't say enough good things about Mary who helped us put them together. We looked at rings for a very long time and finally decided on a very simple but specific ring by a designer that wasn't carried in our city. Seattle Diamonds was the nearest dealer, and I felt hopeful after reading a good review. So we drove the 3 hours up to Seattle to visit with Mary who opened the office that weekend, by appointment.

Mary was wonderful and very patient. She made us feel comfortable and like she cared

I heart this place. I first found them in 2007 when they were located downtown. Erin helped me design a wedding band to go with my engagement ring. I shopped around to a few other places that would make a platinum diamond wedding band, and this place was the most reasonable. Erin provided excellent customer service, and a year and a half later, I still absolutely love my wedding ring set. They look like a perfect match for each other.

Recently, I wanted to have my prongs and diamonds checked on both e-ring and wedding band. Apparently, you're supposed to have this done annually to

Searching for the perfect engagement ring? Need repairs on your fine jewelry? Want an amazing diamond without a huge price tag? Look no further than seattlediamonds.com (aka Gemological Trading Corp or 1diamond.com).

Their new offices are located in South Lake Union, a very subtle location with no signage (you won't be paying for marketing or a fancy store front). We were getting desperate to find the "right" engagement ring for the "right" price and visited them upon a friend's recommendation. We met with Mary and she was by far the easiest salesperson we encountered
