Where to Sell Vintage Costume Jewelry Online

Short answer: sell signed, collectible pieces on eBay if you want the biggest collector audience, on Etsy if the piece is at least 20 years old and you’ll keep a styled shop, and on Ruby Lane if you’re a dealer with an inventory. StillSparkly is a jewelry-only option with free listing and a flat 8% commission, available to US sellers. Lots of unsigned or damaged pieces often sell best locally or as a single online lot.

First, know what you have

Costume jewelry is made from base metals, glass, rhinestones, and plastics rather than gold, silver, and gemstones. That doesn’t make it cheap: what drives price is the maker’s mark, the era, condition, and how wearable the piece is today. Check the back and the clasp for a signature (Trifari, Coro, Monet, Napier, Sarah Coventry, Weiss, Haskell). Our guide to hallmarks and maker’s marks and costume vs fine jewelry explain what to look for. If you can’t tell, the free photo estimate gives you a starting point.

Your main options

eBay: the biggest collector audience

Most costume jewelry collectors search eBay, and its sold listings are the best free record of what pieces actually fetch. Auctions help when you don’t know what something is worth. The trade-off is cost and competition: the Jewelry & Watches final value fee is 15%, charged on shipping and tax too, and your listing sits among a very large number of others.

Etsy: good for older pieces and styled shops

Etsy allows vintage items only if they’re at least 20 years old, so it works for true vintage but not for a necklace from 2012. Buyers there respond to a cohesive shop with consistent photos. Fees stack (listing, transaction, and processing fees, plus Offsite Ads on some sales), so read the fee table below before pricing.

Ruby Lane: for antique and vintage dealers

Ruby Lane specializes in antiques and vintage, with a collector audience that expects knowledgeable descriptions. It’s built for dealers: a shop has a minimum inventory and a monthly fee in addition to sales fees (see Ruby Lane’s fee page), which makes less sense if you’re selling a handful of pieces.

StillSparkly: jewelry only, flat 8%

StillSparkly is a US marketplace that only sells jewelry, including vintage, costume, pre-owned, and handmade pieces of any age. Listing is free, and the seller pays a flat 8% of the item price when it sells. You add photos, review a drafted title, description, and price, and publish. Shoppers can filter by details collectors care about, including era, signed pieces, closure, and finish, and hoops by diameter, a filter you won’t find on eBay or Etsy. It’s a young marketplace, so it has a far smaller audience than eBay or Etsy.

Jewelry resale sites: fine jewelry only

Sites built around jewelry resale, such as Worthy, Louped, and GEMGEM, accept fine jewelry only (precious metals and natural stones, often with a minimum value), so costume pieces aren’t eligible there. StillSparkly is the jewelry-focused option that takes costume jewelry.

Poshmark and Mercari: fashion audiences

These apps reach shoppers buying clothes and accessories to wear now. They can move trendy, wearable costume pieces (chunky 80s earrings, 90s chokers), but collectors rarely search there, and Poshmark’s 20% fee is steep on higher-priced pieces.

Local: antique malls, vintage shops, and estate sales

A vintage shop or antique mall dealer will buy a collection outright, which is fast but pays less than selling piece by piece. This is often the right call for large mixed lots you don’t want to photograph one item at a time.

Fees compared

Fees checked October 2026 on each platform’s own fee page (linked) and they change, so confirm before you list. “Keep on a $100 sale” assumes the buyer pays shipping and counts only seller fees. Full StillSparkly fee details: what you’ll earn.

When StillSparkly is a good fit

• You’re in the US and want to list a few pieces or a collection without paying listing or monthly fees.
• You’d rather be in a catalog of jewelry than among clothing and home goods.
• Some of your pieces are under 20 years old, so Etsy is out.
• You want a draft listing from photos instead of writing every description.

When something else will suit you better

• You want the largest pool of serious costume collectors today: eBay.
• You’re a dealer with a deep vintage inventory and want a specialist venue: Ruby Lane.
• You need to sell to buyers outside the US: eBay or Etsy.
• You want cash today for a whole box: a local vintage dealer.

These aren’t exclusive. Many sellers list the same piece on two sites and remove it from the other when it sells.

Tips that matter for costume jewelry

• Photograph the signature or maker’s mark close up; it’s what collectors search for.
• Name the maker, era, and materials in the title (“Trifari gold-tone leaf brooch, 1960s”).
• Disclose missing stones, plating wear, and green corrosion honestly.
• Price from sold listings, not asking prices. Our pricing guide walks through it.
