You can purchase tickets through the InterGem website at www.intergem.com. Several third-party listing platforms also feature the event and may link to ticket purchase pages. Additionally, some local community boards and event platforms offer digital reminders to help you plan your visit.
Here are a few tips to make your entry smoother:
- Buy your tickets online before the event to save money.

Where Is the San Mateo County Event Center?
The venue is the San Mateo County Event Center, located at 2495 South Delaware Street, San Mateo, California 94403. It is roughly 3.9 kilometers from downtown San Mateo. The facility is easy to reach by car, and parking is generally available on-site.
If you are traveling from San Francisco or the wider Bay Area, the drive takes about 25 to 35 minutes depending on traffic. Public transit options are also available via Caltrain, with the Hillsdale station being the closest stop. From there, a short rideshare or taxi ride gets you to the venue.
For out-of-town visitors, several hotels are located near the Event Center. It is wise to book accommodations early, especially since the show falls around the Thanksgiving weekend — a popular travel period.

Who Are the Vendors?
InterGem events attract a diverse mix of exhibitors from across the United States and beyond. The vendor lineup typically includes:
- Gemstone and diamond traders
- Fine jewelry designers and manufacturers
- Pearl traders and importers
- Mineral and crystal dealers
- Wholesale and retail jewelers
- Goldsmith and silversmith suppliers
- Watch retailers
- Vintage and estate jewelry specialists
Because vendors sell directly to the public, prices tend to be far more competitive than what you would find at a typical retail jewelry store. This is one of the most appealing aspects of the show. Moreover, you can speak directly with the people who made or sourced the pieces, giving you deeper insight into what you are buying.
Booth sizes at the event range from 8×10 feet, and booth fees for vendors typically range from $30 to $100. Electricity add-ons cost around $120. This information is useful if you are a vendor considering exhibiting at the show.
Who Should Attend?
The San Mateo International Gem and Jewelry Show is ideal for a wide audience. However, certain groups tend to get the most value from attending:
Everyday Shoppers: If you are looking for a unique gift or a special piece for yourself, the show offers incredible variety at wholesale-friendly prices. You can find everything from simple beaded bracelets to stunning diamond rings.
Collectors: Gemstone and mineral collectors will find rare specimens that are hard to locate elsewhere. The diversity of international vendors means you are likely to discover something truly unusual.
Jewelry Designers and Goldsmiths: Professionals who create their own jewelry can source beads, settings, findings, and gemstones directly from suppliers. This can save significant time and money compared to ordering online.
Wholesale Buyers and Resellers: Trade professionals can register for dedicated wholesale purchasing programs. Therefore, if you run a jewelry business, the show is a practical sourcing opportunity as well.
Hobbyists: If you enjoy making jewelry as a hobby, you will find a treasure trove of supplies. From simple beading kits to specialized goldsmith tools, the show caters to all skill levels.
Tips for Getting the Most Out of Your Visit
A little preparation goes a long way at a large show like this one. Here are some practical suggestions:
- Make a priority list of what you want to buy before you arrive.
- Bring cash as well as cards, since some vendors prefer cash transactions.
- Take photos of items you are considering so you can compare them later.
- Ask vendors about the origin and quality of their stones — they are usually happy to share.
- Visit the same vendors more than once if needed, as prices can sometimes be negotiated.
- Check the official InterGem website closer to the event date for any special promotions or discounts.
Additionally, note that this show is an indoor and outdoor event, so dressing in layers is a good idea in late November.
Why November Is a Great Time to Visit
The timing of the show is no coincidence. Late November is the heart of the holiday shopping season. Many visitors use the show to find unique gifts that stand out from typical mall purchases. Handmade rings, custom pendants, or rare gemstone pieces make for memorable holiday presents.
Furthermore, buying directly from vendors means you can often have items customized or sized on the spot. Some jewelers at the show even offer engraving or resizing services, adding extra convenience for holiday shoppers.
