About Cathy

Over 40 years I have designed one of kind unique fine jewelry over thousands of pieces for my customers. As now it is my enjoyment to see my customer happy and more than satisfied from my creations. From understanding how the customer wants and desires which inspires me to design a beautiful piece just for that special person and I do make sure the styles, size of diamonds and stones I select will enhance the beauty of the piece to fit in customer’s test. Once I get that, my end product will be defiantly satisfied or more than what customer expected from me.

Each piece I design for my customer I took interest to design what I like and fit into my customer’s test, within customer’s budget which make me feel good as I am able to help my customer to achieve their goals for a beautiful piece and get excited with them which gives me such pleasure just like I can do for my best friends.

I drive for perfection from every angle. I have to be satisfied and excited about my end product for my customers or I won’t deliver the piece until I am totally happy. Normally if I am happy, the customer will love it. That is why I love my work.

Cathy and everyone at East Queen, Thank you for working with Joel in designing such a beautiful engagement ring for me!! I have heard all about the process and can’t wait to meet you in the near future!! We’ll be coming in for our wedding bands. Other than being engaged to Joel, I cannot be more happy about my ring! I highly recommend East Queen Fine Jewelry.

Pauline Russell

I went to Cathy Wang’s to have my engagement and wedding ring’s made into a custom pendant. I didn’t have a clear idea of what I wanted, but just knew I wanted a piece that I could wear in memory of my husband. Cathy exceeded my expectations and stayed within my budget. Thanks, Cathy!
