"Hey Sean, I got the wonderful, beautiful, sparkly diamond rings and earrings! LOVE THEM ALL! I thought the earring hoops might be too big for my face (from the description and from imagining how they would look on me), but I'm gettting used to them and think the size is going to work out just fine! I think I have fat ear lobes, though. It feels like they are being pinched by the clasp. But I am going to give it a few days...see if my ear lobes get used to them. I really like the way they look. You guys did awesome on the eternity ring and the earrings! (as always) I love these new items as I love all the pieces you make for me. Thank you so much."


"George, The ring arrived and Sarah loves it. Thank you for all of your help. I found your team to be easy to work with over the internet, responsive and fair.


"David, I wanted to thank you again for the beautiful ring you so tastefully put together for me. It is amazing. I am thrilled to have it and I tell everyone who looks at it that they have to stop by to see David at Simayof’s in The Grand Canal Shoppes in Las Vegas. There is no better place to buy a diamond ring than with you. Thank you again."


"George...we received the rings today and they are beautiful! Thank you for taking care of us."

Dear David,
We received the gorgeous ring and we love it! Thank you for your wonderful personal service and the service of your staff. We will be back to see you for sure, on our next trip to Vegas.

Dear David,
I just wanted to drop you a note and thank you very much for the beautiful ring which I received yesterday afternoon. It is exactly what you promised and more. I look forward to talking with you and seeing you when I get out to Vegas, and I hope that you will let me know if you are coming to our area.


Just a quick note to say the custom platinum ring was a big hit with Elizabeth. I am very pleased with the finished product and greatly appreciate your expertise in finding the right stones for the setting.


I just wanted to let you know I received my ring and it looks absolutely beautiful! Thank you so much for all your hard work and determination to make sure I had a good outcome with my ring. I only wish that there were more people like you in the retail industry that made customer service issues a more pleasant experience. Please give regards to your jeweler for all his hard work and tell him thank you for the beautiful outcome. I know you are finally relieved that we have this behind us but I am forever grateful! If I ever get the chance to come visit my sister in the future I will stop by so I can personally thank you.


Awesome George!
I really appreciate all your assistance with satisfying all the criteria for my large purchase. I think it will look amazing, plus you made it totally affordable for me, I cant wait to see it. I am glad I came to you.


I got the package. My wife loved the diamond. Thank You!


I wanted to thank you again for everything. I proposed to Christina this past Sunday in a horse drawn carriage thru Central Park in New York City and she said yes….When I pulled the ring out she was breathless and said "oh my god" and just couldn't believe what was going on…..the ring did all the speaking for me and the moment was just magical! Everyone loves the ring and thinks its just dynamite. I couldn't have done this without you."


I just bought an engagement ring and a wedding ring from Simayof in Walnut Creek. These were my 2nd and 3rd purchases from them the last 2 years. My jeweler George Baycan was both knowledgeable and professional and made the whole process very easy. I will always be a customer of Simayof.


"Hello, George. I just wanted to let you know that Jocelyn loves the ring, and I wanted to thank you again for all your help! I've attached pics of the ring."


Jen and I did get engaged on Saturday! The weather was beautiful and my whole plan worked close to perfection. Here are a few pictures of us at the top of the mountain and close ups of the ring with my digital after I found the right setting. Again, thank you for your help."


"Hi George,
My wife is thrilled with the necklace. I can't get it off her. She wears it all the time (shower, exercising), so it will need cleaning very soon."


"Hi George,
I have been meaning to get back to you after giving the engagement ring to Ali. She was so pleased. It looks absolutely wonderful and exactly what she wanted. I truly appreciate all of your hard work. If ever I can help with a referral or post any comments on any of your websites please let me know. Thanks again George, you are a true professional."


Russ and I just received my ring today and cannot say enough about it. The new diamond and the white gold look amazing. Thank you for making my ring look so wonderful."


"Dear David,
Thank you so much for all of your help with my ring. It is definitely the most beautiful ring either of us has ever seen and we were both so impressed with your level of service and care. We will most definitely be in touch when it is time to choose the wedding bands."


What a ring! You guys did an amazing job -- Sharon absolutely loves the ring. Truly, it is spectacular, I am thrilled and she's even more thrilled. Simply, you guys are the very best at your craft! Thank you again for all of your expertise and assistance."

Happy Holidays,


The Simayof Heritage

Our Definition of "Family Jeweler":

For us, at Simayof, your purchase of a Jewel is only the beginning of an exciting long-term relationship – a relationship that embodies and fosters trust and understanding. At Simayof we strongly believe that an educated consumer is a satisfied customer and that this is the core of developing an ongoing successful business relationship.

We aim at being your jeweler throughout the years – during the good times and the bad times, we guarantee to satisfy your needs and wants. We pride ourselves as treating each and every customer as a member of our family, a family that is proud of its tradition.

The Simayof family has a proud diamond and exquisite jewelry design tradition. The Simayof name and the jewelry trade have been linked to each other for several generations and the future promise us an even grander success with the help of our extended Simayof family members who decided to adopt us as their jewelers.

Our desire is to provide you with loose diamonds at and below New York wholesale prices, pass to you our knowledge of the diamond industry and hope that together we can create and design jewelry that will pass in your family from one generation to the other.

We are proud of our rich tradition of designing extraordinary jewels in affordable prices.

A Tradition of Excellence

The Simayof family has a proud diamond and exquisite jewelry design tradition. The Simayof name and the jewelry trade have been linked to each other for several generations, establishing an unquestionable, strong and leading reputation.

For years Yedidia Simayof invested in learning the diamond industry from bottom up. As a diamond cutter he extensively learned the different aspects of optimizing the brilliancy of a diamond and as an owner of a diamond-cutting factory he developed a well-connected diamond dealership net that crossed continents.

In 1987 the Simayof family relocated to the United States and opened its diamond wholesale operation and headquartered it in the cosmopolitan city of San Francisco, California. As part of its perpetual growth, the Simayof family expanded its tradition of excellence to the retail jewelry market. Believing that the retail market was the next logical step in our rapid growth, the family opened its first retail showroom in San Francisco's Union Square in 1989.

Our revolutionary vision and unique experience made Simayof Jewelers and Diamond Cutters an immediate success enjoying years of sustained growth. Simayof Diamond Cutters & Jewelers is now one of the largest self-contained diamond and jewelry emporiums in Northern California.

Believing that the success of the San Francisco retail operation could be expanded into other U.S. markets, Simayof opened its second retail showroom located in The Venetian Hotel and Casino, in Las Vegas, Nevada, in July of 1999.

In May of 2000 we opened our third showroom in the prestigious Broadway Plaza Shopping Center in Walnut Creek, California.

Building on the success of its Las Vegas market Simayof opened one of two new concept stores in the Aladdin's Desert Passage.

The first, World of Charms store opened in December of 2000, it features over 6000 unique charms and is currently the only magnitude charm emporium.

The fourth Simayof location was opened in the Marina/Pacific Heights area in San Francisco in August of 2001.

The only next logical step to expand our retail success was to launch our Website. Our vision of the Internet recognizes that it is a powerful venue that overcomes physical boundaries.

We hope that you will enjoy your experience at and that you will revisit us both on-line and at our showrooms.

Sharing Our Vision:

The Retail & Internet Connection

At we recognize that the Internet is a powerful venue that overcomes physical boundaries. It does not only provide a new way for consumers to purchase diamonds, gemstones and jewelry but it is an amazing communication channel. We believe that the internet is an excellent way for us to introduce the Simayof family jewelry tradition to those of you who may not have an opportunity to visit our brick and mortar locations. The Internet is a worldwide bridge that directly connects between us and our clientele – consumers who visited us from all over the world and fell in love with our exquisite jewelry designs and the quality of our service and prices.

We guarantee to offer the same outstanding, high quality values, to our worldwide Web clients that our San Francisco, Las Vegas and other brick and mortar stores offer.

To our new clientele – because we understand that purchasing a diamond, gemstone or fine jewelry piece may be a daunting experience, we encourage you to browse our Product Education area of our site so you might make an informed decision about your purchase.
