Beyond happy with my experience
I saw a few pieces that I just loved. So I scheduled my first appointment to see the pieces live. By the end of my second visit I couldn't decide so I got two! Incredible service, beautiful pieces and happy with the price.

The process was so seamless
Discovered Jack Weir and Sons on instagram early January 2024 and already made a purchase. Fantastic jewels and even better customer support. Everyone I spoke to was extremely helpful and made the purchase experience very smooth.

I can’t recommend this company enough!
What an amazing experience! I absolutely adore estate and antique jewelry. I found a sapphire and diamond ring in passing and fell in love with it. The company sized it for me.

I finally found the perfect one
After following their account for years, I always dreamed of purchasing a ring! I finally found the perfect one and went in to pick it up. I ended up buying three MORE on top of the original one. Sasha and Gidget were beyond helpful and I enjoyed my entire appointment chatting with them.

Love my new "upgrade" ring!
Sasha was a joy to work with and answered all my questions in a timely manner, of which there were many! I was a bit leery of purchasing such a diamond ring online however I will definitely work with Weir and Sons in the future as they made sure I was comfortable and were there every step of the way.

Thank you Sasha!!!
I finally purchased a stunning piece of jewelry from this family owned business & couldn’t be happier with the entire experience! Sasha answered all my questions, sent me lots of detailed videos & pictures during the process & shipped overnight! Best Christmas Eve ever was opening the box, which included a porcelain ring dish & a box of chocolates!! I will definitely be a customer for life!

Couldn't have been more helpful
Sasha was quick to answer all of our questions and was a complete pleasure to work with. Buying jewelry online has always had an uneasy feeling, Sasha was extremely helpful and made herself available to discuss any of my concerns. I am beyond happy with the look and quality my rings. Thank you again, you have a life long customer right here.

Excellent selections and vert well curated.
I bought a lovely locket at this site . It was well priced and even nicer than the picture . It arrived quickly with its documentation of authenticity as well . Everything was so professional and I could not be more pleased. It was beautifully packaged as well.

A fantastic experience!
I purchased a large, beautiful, Art Deco inspired pear shaped diamond and sapphire ring. It is truly stunning, and I am an extensive jewelry collector (and not easy to impress). I was a little skeptical of making a large diamond purchase online, but it was smooth and easy. Responsive and experienced staff.
