We’re based in Los Angeles. Your marketing is built around where your buyers are.

We’re a jewelry marketing agency in Los Angeles, working for jewelers and watch businesses. We run Google and Meta ads, search, AI search, websites, email and the sales tracking behind them for stores in this city and across the United States and Canada. Being nearby means the people who plan your marketing can stand in your showroom.

Our office is at 6171 W Century Blvd, Suite 350B, and here is how to reach it.

The address

We’re at 6171 W Century Blvd, Suite 350B, Los Angeles, CA 90045, near the airport, so a jeweler from the Westside, the South Bay or downtown reaches us without crossing the city.

The phone

The office answers at (323) 300-2304. If you call outside office hours, leave your name and your store, and we call back on the next business day.

A visit

Write or call before you come by, and we set a time, so the people who would plan your marketing are in the room when you arrive.

Who you reach

You speak with the people who would plan your marketing, whether you call, write through the contact page or come to the office.

A local generalist can find your store on a map. A jewelry specialist knows what’s in the case.

An agency down the street can visit you and still not know what an authorized dealer may run or how a co-op claim gets paid. Here is what comes with your account from the first day, in Los Angeles or anywhere else we work.

Jewelry and watch specialists

Our team has collectively managed $20M+ in ad spend, and we know what an engagement ring needs from an ad that a fashion piece does not.

Our own research on the trade’s ads

We have analyzed 48,332+ jewelry and watch ads across 142 retailers, and we publish what changes in them every quarter. Your campaigns start from that research. Read the quarterly report

Built for high price points

At jewelry and watch price points, the wrong searches get expensive quickly. Our own software gives us tighter control over targeting and spend than Google and Meta offer on their own.

One jeweler in each market

We work with one jeweler in each market. In a city this size, that means agreeing with you what your market is before we start.

Authorized retailer rules and co-op

If you carry watch or jewelry brands, we build inside each brand’s rules on imagery and approvals, and we track every co-op obligation and claim deadline across your channels.

Everything under the marketing, set up for you

Google Merchant Center, analytics, tracking code and the connection to your POS or customer records, whether that is The Edge, Shopify POS, Lightspeed, Zoho, HubSpot or Klaviyo.

We work with jewelers across town and across the continent the same way.

A store in Los Angeles can meet us at the office or on its own sales floor, and a store in another city meets us on a call, with the same team planning the work either way.

The same team, in the room or on the call

The people planning your marketing are the same whether your store is across town or across the continent, and the people running the campaigns sit in the same meeting.

Built around where your buyers are

The ads, the search and the website are built around the part of the city, or the country, your buyers come from, not around where our office is.

Your sales records connect from any city

The Edge, Shopify POS, Lightspeed, Zoho, HubSpot or Klaviyo connect to our sales tracking the same way wherever your store is, so the counter sale is matched to the marketing before it.

One portal, the same two views

Your portal shows the same reporting view and attribution view in Los Angeles, in another state or in Canada, updated as your systems sync.

See which marketing brought buyers to your counter.

Your online store reports its orders to Google and Meta. The sales at your counter stay invisible until someone connects them to the ads, searches and emails that came first.

Online and in-store sales in one view

Our sales tracking matches each recorded sale to the ad, search or email before it, counts it once, and shows you the sales we could not match. The rules behind it come from millions of dollars in jewelry sales we have analyzed.

Budget moved to what sold

Once you can see which campaigns bring buyers through the door, we put more behind them and cut the ones that only bring clicks.

What it looks like when the marketing works.

Questions jewelers in Los Angeles ask us.

These are the questions jewelers ask us most, with straight answers.

Is H&CO actually based in Los Angeles?

Yes, our office is at 6171 W Century Blvd, Suite 350B, Los Angeles, CA 90045, and the phone number is (323) 300-2304.

Do you only work with jewelers in Los Angeles?

No, we market jewelry and watch businesses across North America and in Europe from our Los Angeles headquarters. Each plan is built around where your own buyers are and how they shop, not around our address.

Can you tie an ad to a sale at my counter?

Yes, we connect your POS or customer records, such as The Edge, Shopify POS, Lightspeed or Zoho, to your ad accounts, match each recorded sale to the ad, search or email before it, and count it once. Sales we can’t match are shown separately, and how many we can match depends on what your system records about each buyer.

Do you handle the rules of the watch and jewelry brands I carry?

Yes, we build inside each brand’s rules on imagery and approvals, keep approved brand creative exactly as approved, and track every co-op obligation and claim deadline across the channels you run.

Do we have to sign a long contract?

Ongoing marketing starts with a 90-day commitment, then moves to month to month. A website build, a trade-show campaign or any other project has its own scope and terms, agreed before work starts.

Who owns the ad accounts and the data?

You do, because your ad accounts, tracking code, website and customer data stay in your name. You control access and give us the permissions the work needs. The ads we make with your logo on them are yours too, and they stay with you if you leave.
