Jewelry is a fitting tribute to moments we want to revisit and remember forever. Here is Westlake’s guide to diamond jewelry brands that pioneered the market today:

Joel took time and patiently explained the value of my jewelry and how he calculated it. I believe I got a good, honest deal and I would highly recommend him.

Anne Andrews C. September 28, 2023

I could not have been more pleased and satisfied with Joel at Westlake Gold. If you have spare jewelry and gold that you want to get top dollar for, this is the only place that you need to go. Do not go to downtown LA. Do not go to any jewelry store and especially do not go to a pawn shop! Joel is the only man that you need to see. He is professional, kind, and as sincere and honest as they come. He has a low overhead for his business and he is without question going to give you the best possible price for your valuables. I didn’t even know that some pieces that I had were worth more than I had expected… but Joel being as honest and sincere as they come made sure that I had what I needed and did with a gracious understanding and very friendly demeanor. After leaving this place, I was both impressed and so happy to see that there are still people out there that do care about others. Do not waste your time and go anywhere else… this is the man to see!!!

The team at Westlake Gold was both kind and professional. Joel is very knowledgeable and fair - and I really enjoyed working with him on the sale of some estate jewelry. I highly recommend!

Dana Barrett July 10, 2023

*Respectful, surprisingly great appraisal, very safe and honest.* Joel meets his customers in a clean and neat office inside of an office building, instead of many others in the area. This allows me to feel more comfortable to start with. He was very respectful, friendly, and courteous. The best part comes with the pricing. This was not my first time releasing old gold and jewelry, and I received way more than I thought I would have given my past experience with other jewelry buyers. Thank you, Joel. Wish I had met you in the past, but sure am happy I do now.

What a hidden treasure, pun intended. Overwhelmed with a large collection that I wasn't sure was costume or the real deal. impressed with how each piece was tested even the ones marked for authentication. professional and honest.

janie ahlberg May 14, 2023

If you are looking for an honest appraisal and fair deal, this is the place to go! I walked in with what I thought was seven 1oz Canadian silver dollars worth $25 each, turns out they were 1oz Canadian platinum coins with worth $1,000+ each!! He operated with 100% integrity and patience with me. He took the time to educate me on coins. I will defiantly return!

Patrick rohn September 10, 2020

I bought two rings from Joel and was blown away by the experience. He is extremely honest, professional, and knowledgeable. He normally doesn't make jewelry sales to walk in customers, but just so happened to have exactly what we were looking for. And he even arranged to have our rings resized and polished. They are beautiful and exactly what we wanted.

Stephanie Bland March 30, 2020
