This small family-owned business is THE place for all of your jewelry needs. Allison and Mike are impeccable artisans. Allison customized several pieces of jewelry I had not worn for years into one stunning piece of art. She worked very closely with me designing my signature piece by hand-drawing it to scale. I cannot rave enough about their astute attention to detail. She designed the perfect Art Deco piece to my specifications with her expert artistic ability. The end result of their custom works speaks for itself. Allison and her dad are wonderful to work with. They build a wonderful working

My husband went to LJ Boss to design my engagement ring. Allison did a phenomenal job guiding him through the best setting for a family stone. We went back together to design and create my wedding band, and she was able to take inspiration from different bands that they had in the shop to handcraft a one-of-a-kind band with beautiful detailing. Allison is one of the most patient and talented jewelers. She took her time to make sure that the details were perfect, and bent over backwards with a smile to get me a band that was perfect for our ceremony. She is professional, honest, and great to work

Allison and Mike are the absolute best jewelers around! I can not say enough good things about them. If you want custom and the best customer service anyone could ask for, then you must go here. Allison helped me throughout the whole process of finding the perfect diamond and crafting the perfect engagement ring. She was there for me whenever I had any questions or wanted to see something and came in special on a Sunday evening, the day after we got engaged, to fit the ring before we left for out of town. We have found a jeweler for life. Thank you!!!

Needed an engagement ring sized, and they fixed it in a day. Then, the ring needed to be resized (post engagement) and they turned it around while out for lunch (same day). The ring looks great. Would definitely recommend this company.

Mike and Allison made our wedding bands, custom each. They are very knowledgeable, friendly, and have years of experience. They are also fairly priced and honest, which is very important to our family and friends. Highly recommend their services and have been going there for 15+ years now. Thanks! ;)

These guys are the absolute best jewelers in the Pittsburgh area. Exceptional quality in both the stones and the custom designs. Very fair pricing. Mike and Allison always take great care of me and my family. They consistently demonstrate an obvious passion for their work. We only buy jewelry from them.
