Fantastic experience with Erin at Seattle Diamonds. We scheduled a last minute appointment for a sizing issue and she took great care of my Fiance and I.

We had an excellent experience with Seattle Diamonds. Dave worked closely with us and walked us through the entire process, start to finish, from choosing a stone for a diamond engagement ring, selecting a setting and band, and even choosing a men's wedding band. He did so with patience and top-notch service and stayed in touch along the way. He took the time to help us become comfortable with the process and even understand fundamentals of diamond quality. The rings are incredible, and we're thrilled with the quality and the tremendous value we received.

Dave and his staff at Seattle Diamond are the best in the biz! I worked with Dave to find the perfect engagement ring for my proposal, and my fiance couldn't have been happier with how it turned out. We loved it so much that we went back for our wedding bands too! I will definitely refer any & all of my friends to Dave and Seattle Diamond from here on out.

I cannot say enough about my experience with Dave, Natalya, and Seattle Diamonds. After getting engaged, I needed a fair amount of help to understand the process of selecting and purchasing an engagement ring. Dave walked me through the steps of finding the right stone, worked with my budget, and absolutely knocked it out of the park with the eventual selection. Natalya helped my wife and I decide on an updated engagement band, wedding band, and my wedding ring.

With her advice, expertise, and patience, we were able to select a final set that both my wife and I are elated with. I never felt pressured, always felt welcome in their space, all questions/emails were responded to quickly, and their team created some great memories for my wife and I. 10/10 would recommend this place to anyone looking for quality and professionalism.

Having the opportunity to work with Dave Hall and his team at Seattle Diamonds was great! I first went to Dave in the spring of 2020 to purchase an engagement ring for my now fiancee. A little less than a year later, my fiancee and I went back to Dave to talk wedding bands. Both of these experiences at Seattle Diamonds were incredible. Dave has a real skill of making exactly what you are looking for in your jewelry come to life, while offering his honest guidance along the way.

He really prides himself on quality, and that is exactly what you will get if you choose to go through Seattle Diamonds. We cannot thank him and his team enough for the experience we had and we intend on seeing Dave for future diamond purchases. Ultimately, my fiancee and I are extremely satisfied with the rings we have and look forward to wearing these for the rest of our lives!

My fiance and I had a wonderful experience with Seattle Diamonds. Dave and his team were extremely knowledgeable, friendly, and helped my fiance find the perfect engagement ring in our budget. It's honestly the most beautiful ring I have ever seen. I cannot recommend Seattle Diamonds enough, they are experts and made the whole process so easy and enjoyable.

I would highly recommend for anybody with jewelry needs in Seattle. Erin was so knowledgeable and helpful and went out of her way to help us figure out how we can upgrade our engagement ring. She truly worked with us to find something that would be best for us.

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.

I could not have found a better place to purchase the most perfect engagement ring for my fiance. Dave Hall is extremely knowledgable and was there to answer all of my questions (which was a lot). I did not have a lot of time before I wanted to propose during the holidays, but I had full faith that he would be able to get the job done and he completely exceeded my expectations.

My fiance still is mesmerized by the ring. The diamond is spectacular and she will love it forever. Thank you Dave for helping me throughout this process. It was difficult in the beginning by not knowing much about diamonds, but Dave made the process extremely easy. I will be recommending Seattle Diamonds and Dave to all my friends and family.

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 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 Dave and his team at Seattle Diamonds!

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.

Dave and Seattle Diamonds is the absolute best place to go to get the right diamond to meet all of your needs! Dave is extremely knowledgeable, and he took a lot of time with us to explain and educate us on what was the best diamond for our price range. I felt like he was direct and honest, and it was a much more fun and personal experience then going to a department store or online.

I really trusted them. The staff was also fantastic and was wonderfully helpful when we needed a resize. I would highly recommend Seattle Diamonds for all your diamond needs. We will be going back again, and recommending them to all of our friends! Thanks again, Simone and Miles

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! We can't say enough good things about our experience.you will not be disappointed!

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 be going and I would recommend you do too.

We have just purchased a diamond ring from Dave Hall yesterday and we are completely satisfied both with the diamond as well as the professional service we received. The diamond is definitely one of the better ones I have seen. We feel completely confident with our purchase all thanks to Dave being very knowledgable about the 4Cs of diamonds and beyond. We highly recommend Seattle Diamonds to friends and family.

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. A special shout out goes to Kelsey for helping me through the whole process. We'll see you soon for wedding bands! Thanks for everything.

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 fiance completely speechless. I didn't feel like i was buying from a salesman, but rather an old friend who wanted to see the best for me. Now we're about ready to get married this September and we already picking out wedding rings, and there is no doubt I will be buying them here.

Also let's not forget that the ring appraised for 65% more than I bought it for. I needed that appraisal for insurance purposes, and this just tells me that Dave is completely upfront and spot on with his recommendations. I found out about Dave through word of mouth, and if you're so lucky to read this recommendation on yelp, take my recommendation and go visit Dave yourself. You will not be disappointed.

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 but SUBSTANTIALLY above what I paid. Diamonds are complicated, get help. Had the pleasure of working with Toni and Dave through the purchase of the diamond, designing the ring and wedding band. They are professional, knowledgeable and have more resources than 99.9% of other jewelers. Through each step I knew exactly what I was getting and when I would get it. Would and HAVE already referred friends and family here.

This is a fantastic place. Dave is the most knowledgeable and professional expert jeweler. This is one of those places that you can trust with no hesitation and just follow their advice!

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 protect them from wear and tear. Oops. Anywho, a year and a half had gone by since, but Erin remembered me and had the maintenance done on my rings, complimentary! (I was espcially surprised since my husband didn't buy my engagement ring here.) I guess this service is free for the first few times after you make a purchase here which is super nice.

When I picked up my rings, they were super shiny and all sparkly. Thank you GTC for taking care of my wedding rings! I will definitely come back. Might even pick something else up for myself. (Can I help it if I'm distracted by shiny things?)

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 during the whole ring shopping process. I told her my style based on what we thought we could afford - she stopped me right there and asked me, "What do you REALLY want?" My fiance and I were both shocked when she told us what they could make within our budget.

Several weeks later, we had the most beautiful custom-made ring (at half the price we would have paid elsewhere). Mary even sent it to us via Fed-Ex while we were vacationing in Hawaii! I can't say enough great things about seattlediamonds.com - run here before you waste any time at another "engagement ring store".
