Own the piece
everyone asks about.

I am Maxwell Keller and I own San Diego Jewelry Buyers, the family store that has been on 6th Ave for 20 years. I sell authenticated watches, diamonds and estate jewelry, priced under what the same piece runs on the marketplaces. If you want something that does not exist yet, we build it to your design. And yes, I still buy, lend against, and the bench handles repairs.
Selling something instead? That evaluation is always free.

The collection

Shop the collection.

Every piece is authenticated in house and priced below what the same reference runs on the marketplaces. One of each, so when it is gone it is gone.

Shopping here opens San Diego Jewelry Buyers, my own store, which is where the listings live and the checkout runs.

View everything

No distributor in the middle

We own our inventory outright rather than carrying it on consignment or through a wholesaler, which is why the same reference lands under what it runs elsewhere.

Authenticated before it is listed

Metals tested, stones graded, movements and hallmarks checked in house. Nothing goes up until it has been through that.

One of each

Estate pieces are not restocked. When one sells the listing is done, so if you are circling something, do not wait on it.

Independent reseller. Not an authorized dealer for any brand shown.

eBay Live · Coming soon

Bidding opens at a dollar.

Live auctions on eBay. Most lots start at $1, the clock runs thirty seconds, and whoever is watching decides what it goes for. Pieces close thousands under market on a regular basis, below what a wholesaler would pay for the same thing, because there is no reserve holding them up.

  • Most lots open at $1, no reserve
  • Thirty seconds on the clock, then it is sold
  • Every piece on camera, questions answered live

Follow the store and eBay tells you the second we go on. That is the only way to be in the room when a lot opens.

One message before the first auction goes live. No newsletter, nothing else.

Bring the stones from something you never wear. Most people are surprised what is already in the drawer.

Custom

Have it made.

Engagement rings, a redesign of an heirloom, or a one off you have had in your head for years. You see the finished piece as a render and hold it as a wax before any gold is cut, and the price is agreed before that.

  1. 01

    Tell me the idea

    A screenshot, a sketch on a napkin, or a ring you no longer wear and want turned into something else. Bring the stones if you have them.

  2. 02

    See it before it exists

    You get a render of the actual piece from every angle, and a wax you can try on your hand, before anyone touches gold.

  3. 03

    You approve, then we build

    Nothing is cut, cast or set until you have signed off on the design and the price. No surprises added on the way.

  4. 04

    Pick it up in person

    Finished, sized and photographed. I will show you what changed from the render and why, and it gets adjusted on the spot if it needs it.

Easier to show you.

Real or fake breakdowns, what walks through the door, and the pieces worth a second look. Filmed in the store, nothing scripted. Newest first, straight from the channel.

Maxwell Keller at San Diego Jewelry Buyers

Hi, I'm Maxwell.

I own San Diego Jewelry Buyers on 907 6th Ave, the family business that has been on this corner since 2006. That is 20 years in the same spot, and 2,317 eBay reviews at 100% positive, which is the part I care about most. I sell, I buy, I write collateral loans so people can keep the piece instead of parting with it, and I take in custom work, repairs and appraisals.

Most people who walk in are selling something they never planned to sell. An inheritance, a divorce, a move, a chain that sat in a drawer for fifteen years. You should not have to become an expert overnight to avoid getting taken advantage of, which is the whole reason I write the guides and film what comes through the door.

Everything gets tested in front of you. That part is not negotiable.

Bringing something in instead?

Selling is only one of the options, and it is not always the best one. Here is everything else we do.

I buy

Gold, diamonds, luxury watches, coins and bullion, estate jewelry, sterling silverware and designer handbags. One piece or an entire estate, any condition.

  • Free evaluation
  • Tested in front of you
  • Paid on the spot
Get an offer

Collateral loans

Borrow against the piece instead of selling it. Your item goes into a private insured safe assigned to your loan, never a shared vault, and you keep the right to buy it back.

  • Keep your item
  • No credit check
  • Private insured safe
How loans work

Repairs & appraisals

Sizing, restringing, stone tightening, restoration on something worn, and written appraisals for insurance or an estate. Bring it in and we will quote it before any work starts.

  • Repairs & restoration
  • Written appraisals
  • Quoted first
Bring it in
01

Walk in or book

Booking is not required and free reserved parking is right out front. Most people are in and out in about fifteen minutes.

02

We look at it together

In a private office, not out on the sales floor. XRF analyzer, loupe and certified scales, all in front of you. Your items never leave your sight.

03

You get your options

Sell it, borrow against it and keep it, or have it repaired. If you say no you walk out with everything you brought in, and it costs you nothing.

Buy and sell
from anywhere.

The store is on 907 6th Ave in downtown San Diego. The collection is not. Shop authenticated watches, estate jewelry and designer pieces from any state, and follow the work from anywhere in the world.

Selling or borrowing still happens face to face, because you should watch every step of it. If you are outside San Diego and holding something you are curious about, send me a message and we will work out the right way to handle it.

Drag the globe. San Diego is the big one.

Know what you have.

The questions I get asked in the store every week, written down properly. What the stamps mean, how to spot a fake, and what actually adds value. No prices quoted, no sales pitch.

Start something

Tell me what you have.

Text a photo of the piece, or just describe it. I will tell you whether it is something we buy, whether it can be lent against, or whether it is worth repairing. Nothing is valued or quoted over text, and it costs nothing to ask.

Or book a time to come in →

Ask about a piece and you will usually hear back the same business day.
