Family Operated Jewelry Store Located in Rancho Cucamonga, Eastvale and Mission Viejo.It's hard to believe that 22 years have passed since we first opened Gemma's Jewelers back in November 2001. We've come a long way since then, expanding our selection of fine jewelry and watches and serving countless happy customers over the years. While the time may have flown by, our commitment to providing exceptional service and quality products has remained unwavering. We look forward to many more years of helping our customers celebrate life's most special moments with beautiful jewelry and timeless gifts.
