Our Story

We pride our family owned business on creating unique custom jewelry designed just for you.

Philippe Sigal was brought up in a family in the wholesale diamond industry. At the early age of 16 years old, Philippe was eager to join the family business. His father told him to truly understand diamonds, he would need to start where it all began; rough diamonds. So, Philippe moved to Antwerp where he learned the cutting side of the industry. Once he learned this side of the business, he joined alongside his father buying and selling finished diamonds. He eventually wanted to venture out on his own, so he moved to New York for two years, where he continued in the business. After a visit to Los Angeles he fell in love with the city and climate. Shortly after, he moved out west and continued his wholesale business in downtown L.A., which is where he met his wife, Helen.

Helen Sigal was born and raised in Southern California. At the young age of 19 she began working at Mikimoto Pearls in downtown Los Angeles. This is where she became educated on everything from stringing and matching pearls, to knowing how to grade the different qualities from single A to AAA+. Many of their pieces were set with precious stones and gemstones, which allowed her to learn about diamonds. After 4 years of working at Mikimoto, she then was offered to work in the diamond industry of Downtown L.A. This is where Helen continued her education and knowledge in diamonds. This is where her passion for custom designs began.

One day in a downtown LA. Café the two met and fell in love. Philippe and Helen were inseparable. They soon got married and had two children. Philippe’s business was growing and he needed Helen’s help working in the wholesale diamond business.  In 1992, they decided to open a jewelry store where they could bring high quality diamonds and jewelry to the public at wholesale prices. Later that year, they opened Sigal Diamonds in La Verne, CA.


I have been coming here for 15 years for all my jewelry needs. They have always been very helpful and friendly. All their products are of excellent quality and fine craftsmanship. I only buy my jewelry from Sigal Diamonds.

My husband was recommended to Sigal Diamonds from my mother-in-law who is a long-time customer of Helen and Philippe’s. He bought my engagement ring at Sigal Diamonds a little over a year ago and I was stunned with how beautiful the ring was. Helen and Philippe custom-designed the rings and spent hours with my husband listening to what he wanted. They took the time to make sure everything was perfect. This year for our anniversary my husband bought me a beautiful necklace and again I was amazed!!! I definitely love this jewelry store!

I am SOOOO glad that I went to Sigal Diamonds. I bought a chain in January for a cross that was my grandmother’s. I really didn’t know what kind of chain that I wanted, so their input was super helpful. Helen and Philippe were great with following up with me and returning my phone calls – which is super important to me. I love that I can wear my grandmother’s cross with a beautiful gold chain!

Mr. Sigal created my wife’s anniversary ring for me, which turned out amazing. I was so amazed at how he took my rough sketch on paper and turned it into a beautiful ring for my wife in just a couple weeks. I’ve referred all of my friends to him. Excellent work.
