I thoroughly enjoyed the beautiful work of Gemma’s Jewelers. I’m 30 minutes away from them and am willing to make the drive because they are so caring, thoughtful, and are incredibly thorough with their work. I would definitely recommend.

Amazing customer service, Amy helped us through the entire process of designing my fiancée’s engagement ring and gave us a great price. Way better experience than Zales, Jared, or any other big franchise. Highly recommend!

Gemmas is our new GO to for our future Jewelry Purchases. From the beginning of our search for our 💍 we met Robert in The Eastvale location, he was very helpful and showed us some amazing pieces, unfortunately because I was set on a specific designer “Gabriel NY” he suggested we visit one of their other locations in Mission Viejo. We met his sister Amy (awesome and lovely lady ♥️) As we set on our journey to pick our perfect 💍, Amy and Ken showed us beautiful pieces and even ordered in some amazing samples for us to choose from. We finally found the perfect 💍 and within a few weeks I have my perfect 💍 to wear!! Thank you 🙏🏼 all for the amazing experience and sharing this momentous experience with us!! ♥️ Elizabeth and Oscar
