If you’ve inherited a box of old jewelry, found a drawer of single earrings and broken chains, or you’re simply ready to part with pieces you no longer wear, you have something most people underestimate: real value. Gold, platinum, diamonds, and well-made estate jewelry hold their worth, and turning them into money doesn’t have to feel like a gamble.
It often does, though—because the gold-buying world has a reputation problem. Mail-in envelopes, pop-up “we buy gold” tents, pawn counters that quote you a number before they’ve even weighed anything. The result is that a lot of people sit on valuable jewelry for years, unsure who to trust.
This guide is meant to fix that. It walks through exactly how selling gold and precious metals works when you do it the right way—in person, with people who explain their math—and what to expect when you bring your pieces to Cottage Jewelry on Dempster Street in Evanston. No pressure, no mystery, and no jargon you need a degree to follow.
Why sell to a local jeweler instead of mailing it in?
The single most important decision you’ll make isn’t what to sell—it’s who you sell it to. Here’s why a local, established jeweler beats the alternatives:
- You watch the evaluation happen. Mail-in services take your gold out of your sight, weigh it where you can’t see, and send a check you either accept or pay to have your items returned. At a showroom counter, your pieces never leave the table. You see the scale, the testing, and the math.
- The relationship is repeatable. A pop-up tent is gone next week. A jeweler who has served the same neighborhood for decades has every reason to treat you fairly—they want you to come back, and to tell your neighbors.
- They can identify value others miss. A signed designer piece, a period brooch, an old mine-cut diamond, or a collectible coin can be worth substantially more than its melt value. A generic gold buyer pays melt. An experienced jeweler recognizes when a piece is worth more intact.
- You get paid properly. Reputable jewelers document the transaction and pay by check the same visit—a clean, traceable record for your files. (For larger transactions, payment may be made by wire or certified check.)
Cottage Jewelry has been Evanston’s trusted jeweler since 1973—over five decades on the North Shore. Founded by Ira Rose, it’s a fixture, not a storefront that appears when gold prices spike and vanishes when they dip. That longevity is the whole point: you’re dealing with people who answer for their reputation.
What Cottage buys
Cottage purchases a wide range of precious-metal and fine-jewelry items. If you’re not sure whether something qualifies, bring it in—evaluation is free and there’s no obligation to sell.
Gold (8K to 24K). Rings, chains, bracelets, earrings, pendants, charms—in any condition. Karat doesn’t have to be marked, and pieces don’t have to be wearable.
Sterling silver. Jewelry and qualifying sterling pieces.
Platinum. One of the densest and most valuable precious metals, common in higher-end engagement rings and bands.
Loose diamonds and diamond jewelry. Whether the stone is set or loose, diamonds are evaluated on their own merits (more on how, below).
Estate and luxury watches. Cottage buys watches. (Note: Cottage does not offer watch repair—if you’re selling a watch, that’s the conversation.)
Coins and bullion. Gold and silver coins, rounds, and bars.
Antique and estate jewelry. Older and inherited pieces, which sometimes carry value well beyond their metal content.
Broken or damaged precious-metal pieces. Single earrings, snapped chains, bent rings, dental gold. Damage doesn’t disqualify anything—gold is gold whether it’s a pristine bangle or a tangle of broken links.
If it’s precious metal or it has a diamond in it, it’s worth a look. You can see the full scope on the We Buy Gold and Estate Jewelry pages.
How the in-person evaluation works
This is the part that should feel transparent—and at Cottage, it does. Here’s what actually happens at the counter:
- You bring your pieces in. Walk-ins are welcome during business hours. (For estates or larger collections, an appointment is recommended so the team can give you unhurried attention.)
- A GIA-certified team member evaluates everything in front of you. Nothing goes into a back room. You watch the process at the counter.
- Each piece is identified and sorted. Gold gets separated by karat; silver, platinum, diamonds, watches, and coins are assessed on their own terms. Stones may be examined under a loupe or removed for separate valuation when it makes sense.
- Metal is tested and weighed. Karat is verified (jewelers don’t just trust the stamp), and items are weighed on a calibrated scale you can see.
- You get a clear offer with the reasoning behind it. Not just a number—an explanation of how it was reached.
- If you accept, you’re paid by check the same visit. No waiting for a mailed check, no holding period for routine transactions. (Larger transactions may be paid by wire or certified check.)
- If you don’t accept, you take everything home. No obligation, no pressure. The evaluation is yours to keep as information.
The GIA (Gemological Institute of America) is the most respected independent authority in the gem world—the organization that created the diamond grading standards the entire industry uses. A GIA-certified evaluation isn’t a marketing phrase; it means the person assessing your pieces has formal, recognized training.
How the value is actually determined
This is where most sellers feel in the dark—so here’s the real math, in plain terms.
For gold and other precious metals
Three things drive the offer:
1. Purity (karat). Pure gold is 24 karat (24K). Most jewelry is mixed with other metals for durability, so it’s stamped 10K, 14K, 18K, and so on. The karat tells you how much actual gold is in the piece:
- 24K = 100% gold
- 18K = 75% gold
- 14K = ~58.3% gold
- 10K = ~41.7% gold
A heavy 10K chain can be worth less than a lighter 18K one, because what’s being paid for is the gold content, not the size.
2. Weight. Precious metals are weighed in grams or pennyweights (dwt). More weight of the same purity means more value—simple as that.
3. The current spot price. “Spot price” is the live, global market price for gold (and silver and platinum), and it moves every single day. The same ring is worth a little more on a high day and a little less on a low one. This is the honest reason offers vary between visits—and between buyers who are pricing off the market at different moments. Any reputable buyer’s offer tracks the live spot price; nobody is working from a number invented at the counter.
Put together: purity × weight, valued against today’s spot price. That’s the backbone of any legitimate gold offer.
For diamonds and gemstones
Diamonds aren’t a weight-and-purity calculation—they’re graded on the 4 C’s, the standard GIA established:
- Carat — the diamond’s weight.
- Cut — how well the stone is proportioned and finished, which drives how it returns light. (Cut is not the same as shape; it’s about craftsmanship.)
- Color — graded from D, completely colorless, down the alphabet as faint warmth appears.
- Clarity — the presence of natural inclusions, graded from flawless down to visibly included.
Two diamonds of the same carat weight can differ wildly in value depending on the other three C’s. If a stone has its own GIA grading report, bring it—documentation makes valuation faster and more precise. Cottage’s team can evaluate diamonds whether they’re loose or still set in jewelry.
For watches, coins, and estate pieces
These can break the simple-metal mold entirely. A luxury watch is valued on its brand, model, condition, and market demand—often well above the metal it’s made of. Collectible coins carry numismatic value beyond their bullion weight. And a signed or period estate piece may be worth far more intact than melted. This is exactly where an experienced jeweler earns their keep: recognizing when not to treat something as scrap.
What to bring
You don’t need to prepare much, but a few things make the visit smoother:
- Everything you’re considering selling. Even pieces you assume are worthless—broken chains, single earrings, unmarked items. Let the evaluation decide.
- Any documentation you have. GIA reports or grading certificates for diamonds, appraisals, certificates of authenticity for watches, or original purchase paperwork. None of this is required, but it speeds things up and can support a stronger offer.
- A valid photo ID. Reputable buyers keep proper records of precious-metal purchases, so bringing identification is standard and expected.
- Original boxes and papers for watches, if you still have them—they matter for value.
If you genuinely don’t know what something is, that’s fine. Identifying it is part of the job.
What to expect (and what not to)
Expect transparency. You’ll see the scale, see the testing, and hear how the offer was calculated. Questions are welcome—a good jeweler would rather you understand the number than just accept it.
Expect variation, and understand why. Two honest offers can differ because the spot price moved, or because one buyer pays only melt while another recognizes a piece is worth more intact. Variation isn’t a red flag on its own; an unwillingness to explain the number is.
Don’t expect pressure. There’s no obligation to sell. If you’d like to think it over, take your pieces home and come back another day. The evaluation costs you nothing.
Don’t expect to hear the word “cash.” Cottage pays by check the same visit (wire or certified check for larger transactions). A check is a clean, documented record of the transaction—better for your files and a hallmark of a buyer operating properly.
A quick guide: how to tell what karat your gold is
You can do a little homework before you come in, though final verification happens at the counter:
- Look for a stamp. Check the inside of rings, the clasp of chains, and the post or back of earrings. You may find “14K,” “18K,” “750” (= 18K), “585” (= 14K), or “417” (= 10K). European pieces often use the three-digit number instead of the karat.
- “GF,” “GP,” or “RGP” means it isn’t solid gold. These stand for gold-filled, gold-plated, and rolled gold plate—a thin gold layer over a base metal. Plated items have little to no precious-metal value, though it never hurts to have them checked.
- No stamp doesn’t mean no gold. Plenty of older and handmade pieces were never marked. Testing at the counter is the only way to know for sure—so don’t toss anything just because it’s blank.
Knowing roughly what you have helps you follow the conversation; it doesn’t replace the jeweler’s verification, which is what the offer is actually based on.
Selling vs. appraising vs. resetting—which do you actually want?
Before you sell, it’s worth a moment to be sure selling is the right move:
- If you need a documented value for insurance, estate planning, or a charitable donation—not to sell—what you want is a GIA-certified appraisal, which is a separate service.
- If a piece has sentimental value, consider that an heirloom diamond or family stone can be reset into a new, wearable setting rather than sold. Cottage does this work as part of its custom design—so a grandmother’s stone can become a ring you’ll actually wear, instead of money you’ll spend once.
- If a piece is simply not for you and never will be, selling it turns dormant value into something useful. That’s exactly what the gold-buying service is for.
A good jeweler will tell you honestly which path fits—even when one of them means they don’t buy your piece.
FAQ
Do I need an appointment to sell gold? No—walk-ins are welcome during business hours (Tue–Sat, 11 AM–5 PM). For estates or larger collections, an appointment is recommended so the team can give your pieces unhurried attention. Call (847) 328-1420 to set one up.
How will I be paid? By check, the same visit. For larger transactions, payment may be made by wire or certified check. There is never any obligation to accept an offer.
Will you buy broken or damaged jewelry? Yes. Broken chains, single earrings, bent or worn pieces, and dental gold all have precious-metal value. Condition doesn’t disqualify anything.
Do my gold items need to be marked or stamped? No. Many older and handmade pieces were never stamped. The team tests and verifies karat at the counter regardless of markings.
Why might your offer differ from one I got elsewhere? Most often it’s the live spot price, which changes daily, or the difference between a buyer paying only melt value and one who recognizes a piece is worth more intact—such as a designer item, an antique, or a collectible coin. Cottage explains exactly how each offer is reached.
Can you tell me if my piece is worth more than its metal value? Yes—that’s one of the main advantages of selling to an experienced jeweler. Signed designer jewelry, period and antique pieces, luxury watches, and collectible coins are often worth more intact than melted, and the evaluation accounts for that.
Do you buy watches and repair them too? Cottage buys estate and luxury watches. Watch repair is not offered—if you have a watch, the conversation is about selling it.
