Rich was recommended to me by a friend, and I can see why he gets so much business from referrals. I worked with Rich to design and buy an engagement ring + diamond. Rich was super responsive and knowledgable throughout the process - it didn't feel like a sales transaction at all. My partner and I are extremely happy with the end product! Would highly recommend RTL!

Couldn't recommend Rich more. He went above and beyond every expectation I had every step of the process. From general education on what I should be looking for, to helping pick out, to the final steps. Anyone looking to get the most value for the best price should contact Rich. He took the time to get to know me, what I wanted, what I thought "she" wanted, and ensured I was thrilled with the product. And I was! But more so, my fiancee hasn't been able to stop smiling. Thank you Rich!

Couldn't ask for a better experience with buying a ring. Rich is incredible at this, and choosing him was the best decision I could have made for buying an engagement ring. He's honest and straightforward in an industry where everything can be so easily muddied by marketing; with him the whole process is transparent. I went in knowing absolutely nothing about diamonds or rings, and he caught me up on all the different variables of ring-buying step by step.

There were no pressured sales tactics -- I just set a budget and he helped me optimize to it. The whole process took two weeks, but could have gone faster if I had needed to. My now-fiancee couldn't be happier with the ring. Especially if you're new to this, give Rich a shot!

I highly recommend Rich for any custom jewelry pieces. He has access to both remarkable stones and has the creative resource team to help design and build your custom piece. I have created 3 stunning rings with him. You will not find a better source for fine jewelry with fair pricing.

Rich was great to deal with, really got the best product for the price. It was really nice to be able to have something that was customized completely.

I don't generally don't write reviews, but since I found Diamonds SF on Yelp and was so happy with my experience there, I felt compelled. I visited many places and saw dozens of diamonds before I made an appointment to see Rich. I'm glad I did, because it allowed me to immediately realize that I was finally in the right place. I was shown exactly the stones I was looking for, they were clearly of the highest quality available, and best of all they were at better prices than I had encountered elsewhere.

Rich was extremely knowledgeable, and was able to help me narrow my choices without ever trying to upsell me. Once we had decided on a diamond, he worked with me to custom design the perfect ring, inspired by Tiffany & Co, but uniquely my own. Thank you for your help and experience, and to anyone considering buying a diamond or some other piece of jewelry, make sure to check with these guys before you do anything. Wonderful, wonderful experience!

Rich is absolutely amazing at this. He made the process of buying a Diamond so easy. Looking and searching for the right diamond can be overwhelming and kinda scary. Rich's selection is stunning also. We looked for the right diamond for months until we found Rich and then couldn't make a decision only because he had so many beautiful diamonds to choose from.

He also explained the clarity, size and color better than everyone we have talked to. He returns email, text and phone calls promptly and makes you feel like you are his first priority. Thanks Rich, she loves it and will be returning for all jewelry from here on out
