My second time returning to Biondi Jewelry store. I’m so happy to work with Tara once again. Getting additional rings resized, very happy with my other ring that was resized!😁 Now working with a custom order. Very happy with the process so far! 😁
I had a custom emerald and diamond ring made from jewelry I had on hand. I LOVE the result . Michelle was so easy to work with and the jeweler listened to what I wanted and delivered. So happy and Merry Christmas to me!
I took 3 rings in (family jewelry) to have a new wedding ring made. I can't believe what I got. It is absolutely beautiful. I could have never imagine it looking like this or even having anything so beautiful. The quality of the ring is amazing and the service was even better. Davis was so patient with me and was so thoughtful. In fact everyone in the store was great. They really made me feel like family. Thank you Biondi team.
Biondi is a lovely store! The staff is exceptional and helped me find exactly what I was looking for. They have a vast range of timeless, classic, and beautiful pieces, and making a special purchase is accessible in every price range. I am thrilled with my experience and will undoubtedly be shopping here again in the future (and I will also send my husband in to preview my wishlist!)! Thank you, Biondi! 🫶🏼 💎
Biondi is primarily a family owned business. I have been a Biondi customer since the around the end of 2023. Each time I’m go into the store, I feel like I’m special and the only customer. I have had a stud earring made, a wedding band for my husband, a diamond band for myself and another ring for my husband modified by putting a diamond in the middle of his turquoise stone. I would describe the family as honest, personable and reliable. Satisfaction guaranteed at Biondi.
