    Clearly see the area they cut and soldered the ring
    Linda C.

    I am SHOCKED of these BS lies of a review on here. I brought my BRAND NEW RING only gotten the night before to get resized. It was so shiny and spotless til this place just destroyed its platinum band. UNFCKN BELIEVABLE. I will be going back and confronting this shop

    Danny always takes amazing care of me when I need anything from custom jewelry, resizing, and cleaning! He never fails to bring my vision to life! Thanks again to Rainbow Gems!

    Daniel at Rainbow Gems is one of the most genuine businessman I know. He and his team of jewelers worked tirelessly to help me create one of the most beautiful engagement rings I have ever seen. Not only did he source fantastic diamonds, but he and his jewelers spent days making adjustments to make sure that the ring met my expectations. Not only did they create an stunning piece of art for me to give to my fiance, but they met with us the day after I proposed, on a Sunday of all days, just to make sure that the ring was sized and ready for the love of my life to wear! My fiance loves the ring so much she never wants to take it off. She rarely boasts about material things, but she just can't help but show off her piece of art to the world. There really is no way I could ever thank Daniel and his team enough. All I can do is write this review and provide my ultimate recommendation. If you are looking for custom designed jewelry at a competitive price with excellent service on top, then Rainbow Gems is your store.

I was looking to pay over $80 at OTHER places.... and then along comes Margarita. I called Gemma's to inquire about pricing and there was something about Margarita ( friendly and funny) that convinced me that I found my place. Walked in and was greeted right away by Margarita and Ceasar. Took about 45 minutes for services to be completed. This place had many beautiful pieces- from rings, to necklaces, to bracelets, and even jewelery for kids. Not to mention watches too! If you're in the market for a beautiful piece of jewelry- come to Gemma's. Not only will you find knowledgeable assistance, but you'll find timeless quality pieces as well. Battery replacement $15 x 3= $45. Sizing -$10

I actually told my sister, "I'm not even looking to purchase another ring, but the way this woman is making me feel, if they can't do what I want, I may end up buying another engagement ring anyway!" What made the experience even more meaningful was that I had literally just walked out of another jewelry store nearby after having a very unpleasant experience. The difference between the two businesses was night and day. The moment I approached the door and rang the bell, I was immediately welcomed inside. I met both Margarita and Caesar, explained what I was hoping to create, and Caesar instantly began assisting me with professionalism, courtesy, and kindness. I came in looking to create a custom engagement ring using two rings I had already purchased, and they immediately reassured me that it could be done. Not only were they knowledgeable, but they truly cared about helping me make the right decision. Caesar and Margarita listened carefully to the direction I wanted to go while also offering thoughtful guidance and options I had not even considered. Margarita especially emphasized how important it is to choose the right ring for such a meaningful moment in life, and I completely agreed with her perspective. They provided me with a fair quote, patiently walked me through different possibilities, and then showed me several beautiful rings in the store that were honestly far better than what I had previously purchased elsewhere. What stood out most was not just the jewelry, but the atmosphere they created. They made me feel respected, important, and appreciated the entire time I was there. Their professionalism, friendliness, and genuine customer care completely changed my experience and restored my confidence during what should be a joyful and memorable purchase. Thank you, Margarita and Caesar, for your outstanding service, honesty, warmth, and professionalism. Experiences like this are exactly why businesses like yours deserve to be recognized and supported.

Wanting to support a local mom n' pop business, I went to Harry for a custom made engagement ring. I brought a picture of a simple, elegant, solitaire ring I found online and asked Harry for his professional opinion regarding the layout. After some back and forth we decided on the final design and in an effort to ensure we were on the same page, I wrote down what we agreed to on the paper with the picture and gave it to him to fabricate. I picked up the ring and was so excited that I didn't realize the diamond was going the wrong way from what we had discussed until I got home. I went back and Harry looked at me like I was crazy. I asked him to produce the paper with the picture and written instructions and after a token glance around his office, he said he had shredded it. Convenient. Thinking this might have been fate, I suggested a compromise. I would propose with the ring as-is, but if my fiancé wasn't happy with the layout, I asked if Harry would be agreeable to rotate the setting to the way we had originally discussed. He agreed and that was that. I proposed and she said yes....soon afterwards, she asked why the stone was laying the way it was. I laughed and told her the story. We both took the ring back to Harry and as promised, he rotated the setting to what we had originally agreed to. Now I didn't mention this at first because I thought that in the process of the repair it would be resolved, but the ring and setting were never exactly perpendicular to one another. It was crooked from day one. After picking up the ring with the setting now in the correct position, I could tell it was still crooked but was reluctant to say anything. We took it home and thought maybe we were being too picky but we decided to just go with it. After showing her mom and girlfriends, everyone remarked how beautiful the ring was but only the bravest people closest to her remarked on how it was crooked. We begrudgingly decided we'd have to bother Harry again. We went back and apologetically told him that the ring was crooked. He looked at us as if we had three eyeballs each. He placed the ring on his mandrel while aggressively denying that it was crooked, telling us that it was an optical illusion. That our eyes were playing tricks on us....and everyone else's apparently. Sarcastically, he joked and said if "we wanted him to "fix it" and make it crooked" that he would. Eventually, he gave me the ring back from behind the glass and I calmly said, Harry, this thing is obviously crooked but if this is the quality of the product you're willing to put your name on, then I guess there's nothing that can be done. He insisted that we were wrong and sent us on our way. My fiancé and I took it to another jeweler and presented them with the ring. Careful to not lead them with my questioning, I handed it over and simply asked "do you see anything wrong with this ring?" Without hesitation, and with a somewhat disgusted look on her face, she responded "yes, it's very crooked." I asked if she could repair it and she said she most definitely could. Thanks to them, the ring is now perfect. Harry was very personable but I got the feeling he wasn't really paying attention to what I was asking for which is why I was so careful to write down what we agreed to. I gave him the benefit of the doubt thinking that it was probably such an easy project for him that he simply understood what was being asked of him. He fixed his mistake once and that was all we were going to get. The setting was so obviously crooked that there was no way he couldn't see it. That being the case, the only logical conclusion I could draw is that this project was no longer profitable for him and he would rather say it was us that were wrong and send us away rather than putting another minute of his own time into this ring. If all else, we have a fun story to tell about the ring and I suppose I should be thankful for that. Harry, if you still have my contact info, you can still make this right. Thanks for the beautifully crooked engagement ring.

However, as a consumer, I rely heavily on ratings and reviews when choosing a business, so I feel it's important to share my experience. I have lived in Rancho Cucamonga since 1989, and it has been a very long time since I've encountered the level of discrimination, prejudice, and racial profiling that I recently experienced at this jewelry store. I was previously married for 18 years before my wife passed away. Recently, I've been blessed to find someone new who has brought comfort and healing into my life. I am now at a place to express my appreciation and commitment. I have been searching for an engagement ring for over a year. I have visited many jewelry stores and while service varies some, I had never been treated in a way that made me feel unwelcome, until this experience. I had previously purchased a ring while traveling out of state, but after closer inspection, I decided it wasn't the right choice. I then ordered another ring online because it closely matched what I was looking for, and the 30 day return policy gave me confidence to try it. However, once it arrived, I had concerns about its authenticity and simply wanted a professional verification. When I first visited this store, I was addressed through a doorbell camera and was not even allowed inside. I was told they do not perform appraisals. I left, but later returned with the intention of inquiring about a custom ring using pieces I had already purchased, as well as verifying whether the stones were genuine diamonds. Upon being allowed inside, the experience did not improve, the service was cold. The gentleman assisting me was unfriendly, walked away and offered no meaningful assistance. His communication was dismissive and rude. Another employee briefly assisted me, but when I asked if they could test the stones, I was told "No they can't do that you purchase it." This was surprising, of a jewelry store. When I asked about custom work, I was quickly handed a business card and told to email details. With no effort to even look at the ring, despite being the only customer in the store. I left and contacted another jewelery store and asked if they could test diamonds, immediately response was, "Of course we are a jewelry store." The difference in professionalism and customer service was clear. Ultimately, I chose to purchase a brand new engagement ring from that second store. Their team was welcoming, attentive, and made me feel valued as a customer.
