Sell Antique & Vintage Diamond Jewelry in Northbrook, IL
Antique diamond jewelry often carries value beyond its materials. Because craftsmanship, rarity, and era matter, a well-made piece can outperform a modern style with the same total carat weight. If you want a local diamond buyer who understands antique details, we can help you price it the right way.
What makes antique pieces stand out?
First, older rings and bracelets often use platinum with delicate, open filigree work. Next, hand-finished settings can show a level of detail that modern mass production does not match. In addition, certain gemstone combinations—such as sapphires, rubies, or emeralds alongside diamonds—can increase interest.
- Metal: platinum and heavy gold settings can help
- Design: filigree, engraving, milgrain, and hand-set stones
- Era signals: Edwardian and early 1900s-inspired looks often draw demand
- Center stone: larger, brighter stones generally perform best
However, not every “old” item is automatically valuable. Condition still matters. Therefore, we inspect prongs, wear, repairs, and any missing stones before we finalize an offer.
How we evaluate antique and vintage diamond jewelry
To begin, we look at the diamond itself: size, cut style, and overall appearance. Next, we review how the setting contributes to desirability. For example, a clean platinum filigree mounting can add value because buyers often seek that exact look. Then, we consider whether the piece fits a recognizable design family or brand.
What to bring (or send in photos)
- Clear photos of the front, side, and any hallmarks or stamps
- Any paperwork, appraisals, or previous repair notes
- Matching pieces (bands, earrings, pendants) if you have them
Good news: You do not need a certificate to get started. Photos and a short description can still produce a useful estimate, and then we confirm details during inspection.
Private appointments in Northbrook (and safe mail-in options)
Since we meet by appointment, you can sell discreetly in a private setting. That makes the experience calmer, especially for estate jewelry and sentimental items. Additionally, if you live out of state, we can discuss insured shipping after a photo estimate.
Next steps
- Send photos and details for a fast estimate.
- Schedule a private appointment in Northbrook, or confirm insured shipping.
- Review the offer, then choose what you want to do.
Finally, if you’re unsure whether a piece is truly antique, don’t guess. Send photos and we’ll help you identify the style cues that matter.
Value boosters (and what can lower the offer)
Because antique jewelry is often one-of-a-kind, small details can move the price. For instance, a clean hallmark, a balanced design, and secure stone setting tend to boost buyer confidence. On the other hand, heavy repairs, missing side stones, or weak prongs can reduce the final number because buyers must budget for restoration.
- Boosters: intact filigree, strong prongs, matching sets, and high-quality center stones
- Reducers: loose stones, chipped edges, bent metal, or obvious replacement parts
Still, you don’t need to “fix” the piece before you reach out. In fact, repairs can sometimes hide original features. Instead, contact us first, share photos, and we’ll guide you on the best next step.
