Wendy and her staff went out of their way to help me choose a beautiful Tiffany diamond engagement ring. I am from out of state and utilized their user/shopper friendly web-site to look through their large inventory of rings. After finding a few rings I was interested in, I just reached via phone and spoke with Wendy and she immediately started helping me and offering me great advice and information.
Wendy and her staff were extremely efficient and helpful throughout the buying process and then through the delivery process. There was great communication as well.

When they give you a guaranteed price, beware, as that does NOT mean they are going to buy it. They ask for pictures and documentation, they do their own research and then, give you a GUARANTEED quote. Then they renig if they want, after they see it, even if it is exactly as the pictures show. Wasted days and turned down other offers. The guarantee is meaningless You are much better off not selling to them

Incredible, personalized and professional service!
I quickly came to a very fair deal to sell my earrings. They mailed the check FEDEX and it arrived fast. I very much appreciate Alon and Wendy's awesome customer care. This company is simply the best place to sell jewelry. Absolutely fantastic experience!

Purchased a tiffany diamond engagement ring from Wendy off of ebay. She really helped me out a bunch and was so responsive through ebay and over the phone. She provided a great service and I will definitely be buying jewelry from The Diamond Oak in the future! I will post a picture of the ring on my significant other’s hand once I propose on here for you guys!

The Diamond Oak is a top-notch, professionally-run business with a diverse, high-end jewelry selection. From the start, Alon was exceptionally responsive to our many inquiries and gave us a great deal on a beautiful Tiffany ring, and he couldn't have made our experience any better. My wife and I were skeptical of buying a ring over the internet at first, but Alon put our minds at ease and everything was on the up and up. You can't go wrong with this business and I highly recommend their services. Thanks again!

I had the pleasure of working with Alon and Wendy when I decided to sell my engagement ring. They both made the process incredibly easy and Alon offered me the best price compared to other retailers I reached out to. I can't thank them enough for their professionalism, fast and clear communication, and their integrity. I'd recommend them to family and friends, and hope to be a buyer for their pieces sometime soon. I don't write many reviews in general but they are amazing!

I recently had an excellent experience purchasing from The Diamond Oak. I had initially seen the piece in a listing online and was happy to see that The Diamond Oak has a physical store so I could call directly. Alon was extremely patient in answering all my questions (even though I called and asked them over multiple days) and was clearly very knowledgeable. In the past, I have worked with different businesses that say they will follow up on a question I had but I've typically had to remind them before they responded again, so I was very surprised when Alon followed up on a document he had

Alon and his team went above and beyond to ensure that my selling experience with them went as smoothly and painlessly as possible.
Excellent customer service that didn't feel distrusted or delayed even in the slightest, which was a pleasant surprise considering there is a 3 hour difference in our time zones.
Offered me a fair price and made me feel very confident and safe with his company's process.
I'll be recommending him to anyone who needs to sell or buy, I couldn't imagine a better experience than the one I had with them.
Thanks a bunch to Alon and Wendy, you guys are

We sold our diamond ring to The Diamond Oak, the whole process was so simple and smooth. We contacted them for a quote, and then they guided us on how to securely mail the ring to them. Once they had the ring and we had a final offer for the diamond and the platinum, we confirmed the sale, and the money was in our account within a day. It was so much easier than we expected, and the process felt safe and secure.

We first me Alon about 7 years ago when we began searching for an eternity band. Although we did not purchase the band until a year and a half later; his professionalism, helpfulness and easygoing personality made it a pleasure doing business with him. Since then, we have purchased diamond earrings and assisted my brother in purchasing a pave diamond ring and earrings for my sister-in-law. Each piece has the same exceptional quality and painstaking attention to detail. They have all exceeded our expectations. We have total confidence in Alon and will only go to him for our jewelry.

Diamonds truly are forever. They represent love and longevity, strength and power. Diamonds are social status markers, which is why most women wish for their engagement rings to be on the larger side. Diamond engagement rings are representative of the depth of our relationship. So, when shopping for a larger engagement ring, most people want to do it one time, which means they've gotta get it right the first time-- A person can do one of two things: 1) He can have the generic retail experience, wherein entry level sales associates are conditioned to agree with every statement you make and

I've known Alon for nearly 2 decades and all I can say is, "WHO DOES THAT?!"
Who travels from NYC to our Nation's Capital to show 3 stones in person because of my inability to conceptualize via photos?
Who tells you to go with the smallest of the 3 stones having known my wife's personality and that since her finger is beautifully, unusually & thankfully THIN, anything else would look too ostentatious in her eyes?
Who does all this for a procrastinator in an effort to save his marriage by turning around a custom made ring in 3 weeks just in time for his 25th Anniversary

This is a trustworthy, reliable, and professional jewellery seller and diamond merchant. At first I was anxious about buying such big-ticket items online, but after corresponding with their head, Alon Mor, and visiting their place in the Diamond District of NYC, I am thrilled to have now found my go-to jeweller. They sell antique, vintage, modern, and custom made-to-order fine jewellery, and can do repairs, appraisals, and design. I live in the Middle East but fully intend to be turning to The Diamond Oak to find gifts for my partner for years to come.

I recently received a gift for a milestone birthday from my husband. It was a family heirloom ring that Alon and team painstainkingly restored with the utmost care and precision. The ring was lovely before but after it was restored, with some additional design elements, it was absolutely stunning. Alon worked closely with my husband to get the ring exactly right, sharing mock ups and design ideas with him along the way. We both could not have been more pleased with the outcome. Not only is Alon extremely concerned with his client's happiness, he is also the only person we trust with our precious

I've been buying from, Alon Mor, The Diamond Oak, for more than 20 years. Diamonds are a bit intimidating to buy, and requires a lot of trust. I feel 100% comfortable with Alon. Most recently I bought a 5.50 ct round, with side baguettes in Platinum. I was in a bit of a time crunch, Alon was able to deliver a handmade custom ring within 2 weeks, without any compromise in quality. The ring was a knockout ! I highly recommend Alon Mor and The Diamond Oak for all custom diamond Jewelry.
