Buying Antique Jewelry Online: 6 Mistakes to Avoid
Looking to buy antique jewelry online? It’s a wonderful way to discover rare and meaningful pieces—but buying without the right information can lead to costly mistakes. Here’s how to shop smart.
Not checking hallmarks or metal quality
A proper authentic antique piece should include visible hallmarks, indicating metal type and quality (like 18k gold). Always ask for clear photos and mention of gold or platinum content.
Overlooking the style and era
An Edwardian pendant or an Art Deco ring? Every era has its codes and value. Make sure the seller identifies the period and design style.
Buying without a certificate or invoice
A certificate from a qualified gemologist adds trust and value. An invoice gives legal proof of ownership. Avoid sellers who don’t provide either.
Note: Maison Mohs provides a certificate and a detailed invoice that includes hallmark information. All precious stones are evaluated by Angéline Chanson, a certified gemologist. When needed, the expertise can be supported by a laboratory certificate, most often issued by the French Gemmological Laboratory (LFG) in Paris.
Relying on poor or limited photos
You should see the front, back, hallmarks, and close-ups of the stone settings. Blurry or minimal photos are a red flag—ask for more.
Ignoring return policies
Even online, you should have a right to return. Look for sellers who offer a clear return window and process.
Please note: consult the Maison Mohs T&Cs
Shopping on non-specialist platforms
Avoid mass-market sites with anonymous listings. Prefer vetted dealers, vintage boutiques, or platforms with professional curation.
Bonus: Maison Mohs offers bilingual service, certified appraisals, and a secure online shopping experience.
Why After-Sales Service Matters
Before purchasing antique jewelry online, make sure to check the seller’s after-sales policies. Can they resize your ring? Help if a stone falls out? Offer repairs or custom engravings? These are essential questions that can impact the long-term value and wearability of your piece.
At Maison Mohs, after-sales service is part of the experience:
-
Repairs: Small fixes (soldering, prong tightening, clasps) are handled through trusted workshops.
-
Stone security: Loose or missing stones are promptly restored by our experts.
-
Resizing: Most rings can be adjusted to your finger size.
-
Engraving: Names, dates, or initials can be added for a personal touch.
A good after-sales policy ensures your jewelry lasts and remains wearable for years to come.
In summary
Buying antique jewelry online can be a wonderful adventure... provided you know what you're buying. By avoiding these mistakes, you'll have the best chance of acquiring a piece that will last a lifetime.
