Vintage Costume Jewelry Evaluation and Research Service

Garden Party Collection offers valuations for vintage and antique costume jewelry. We do not appraise fine estate jewelry, "fine" defined as any item in precious metal with genuine or precious gems. We evaluate and research vintage costume and period jewelry only. We receive dozens of "what's it worth" questions via email per week and as a result, we do offer an evaluation service (see below), one of the only vintage jewelry evaluation services on the net. Evaluating your jewelry takes time and expertise as each item requires research. There is a vast resource of info on the site and we're happy to give you info about dates and marks if we can. However, all emails requesting detailed info, historical research and/or a value will be referred back to this page, and to the next paragraph for info on our evaluation service. If you are interested in brief, general info, without value and research, you may contact us via email.

To evaluate any item we require either a photograph or the item itself; we cannot evaluate based on a written description. You can email a photo attachment (front and back of jewelry required) to the email link below. If you'd like to send us your item, please request this in advance via the comments box in the shopping cart as you complete your evaluation order during checkout. If you send us your item, you must send it insured. We will return it insured (no additional charge) and can include a photo (by request) of the item as well as the written valuation.

Please note: We are not certified appraisers. Any valuation received from Garden Party Collection is not certified and therefore may or may not be accepted by some insurance companies. Valuations are based on our expertise and 20 years of experience in the antiques and collectibles business specializing in antique & vintage costume jewelry.

We do buy vintage jewelry all the time and if you are interested in selling your vintage jewelry to us, we will not be able to do the appraisal, it is unethical for any dealer to appraise jewelry they might purchase for resale. The appraisal or current market value is different from the value we would use for purchasing any item.

Fill in the fields and continue on to complete your order for a vintage costume jewelry valuation. You can use the form for more than one item, separate info for each item with commas. Please include as much info you can, either in the box below or via email to info@costumejewel.com including where you got it, what's it made of (to the best of your knowledge), and any marks on the piece. We need this info to be able to do a thorough research job.
