About us 

From Ani Diamond Designs to Gems by Trevor

Gems are wonderful. I love them.

After more than forty years’ experience in jewelry business in Metropolitan Detroit and San Francisco, I am excited with the potential of reconnecting with my customers and friends through this website and have the opportunity to give you all the useful service you need. 

Working with customers for their satisfaction was always the main priority in our business.

So, now I am specialized and focusing on custom design items with precious stones. 

Our services include but are not limited to:

- Servicing the jewelry items, you already have; by cleaning, checking, remodeling as well as recommending if they need any repairs or other cautionary measures.

- Identifying and appraising precious and semi-precious gems that you may have in your possession.

- Helping you obtain and design the jewelry piece with the gem of your liking.

- Answering and consulting in gem and jewelry related questions.

So please do not hesitate to contact me if I can be of any help. I would love to hear from you!

Please make an appointment, which gives us the possibility to meet us at our both convenience.

Sincerely yours,

Trevor Pilibosian
GIA Graduate Gemologist
