I would highly recommend Jewelry By Leonard Design! We have used them for many years from small battery replacements, repairs and jewelry cleaning to much larger work! I take my engagement and wedding rings each year to them to be cleaned and checked. They always take the time to fully look over the ring and the diamonds to make sure they are not lose and everything is secure.
Recently, I had to have the prongs on my engagement ring replaced. We were able to schedule an appointment with the jeweler and my husband was able to be in the back and watch all of the work being done. Totally trust them

I purchased 2 custom "wave" rings in white gold. There's 5 diamond chips; and I just love them! They're nice and smooth so that they won't pop my balloon sculptures (I'm a professional balloon artist). One of the rings was too tight, and they did the adjustment for free! $400 each.

While picking up the resized ring, I decided to buy this beautiful crucifix on a stainless steel chain. $30.

Great pricing, along with OUTSTANDING customer service by Gaby, and you've got a 5-Star Business.

I'll be buying all my jewelry from them from now on.

Absolutely amazing! I went to a jeweler in Matawan and they said they can't resize it and I should return it. I went to Jewelry by lenords they took the engagement ring from a 7 to a 6 and they did a fantastic job! They were so nice and wanted to help anyway possible! If you are looking to get your ring resized I highly recommend this place, they are affordable, super nice and they did mine the same day! I couldn't express how thankful I am for them!

My favorite jewelry store ever! Carlos worked with me to create my dream ring (posted a picture above of my all diamond 3 band rolling ring). I honestly cannot stop staring at it!
Thank you so much for making this stunning piece of jewelry!

Place is awesome! Originally, I chose them because of their high reviews. I needed to get my chain repaired and they worked diligently to make sure I had it done within the hour. I was in a pinch and needed it fixed as soon as possible. The repair was done beautifully and cleaned ever better! Highly recommend to anyone looking to purchase jewelry or jewelry repair. Will definitely be back.
