Tips for Spotting Authentic Designer Items & High Value Jewelry

April 22, 2025

Authentic designer items and high-value jewelry can be easier to find and possibly cheaper than you might think, thanks to pawn shops and thrift stores. For those who buy and sell jewelry regularly, identifying genuine pieces is an essential skill. Whether you're searching for a bargain or looking to make a profitable sale, knowing how to separate real pieces from fake ones is key.


Here’s your quick guide to ensure your next purchase or sale is a confident one.


Examine Hallmarks and Stamps

Authentic pieces often feature stamps or hallmarks indicating the type of metal (e.g., 14K for 14-carat gold), purity, or the maker's brand logo. These marks are typically located on inconspicuous areas, such as the inside of a ring or the clasp of a necklace. For high-value designer jewelry, the brand's logo or signature is a strong indicator of authenticity. Check that it matches the standard font, size, and placement used by the brand.


Inspect the Craftsmanship

High-quality jewelry and designer items are known for their exceptional craftsmanship. Look closely at the details:

  • Are there any rough edges or visible glue marks? Genuine items will have a flawless finish.
  • Check for weight. Authentic pieces are often more substantial because they use high-quality materials.
  • Moving parts, such as clasps or zippers, should operate smoothly and feel sturdy.


Look at the Materials

Designer items and high-value jewelry often use premium materials like gold, sterling silver, platinum, or real gemstones. A quick test with a magnet can help identify whether a piece is genuine; most authentic precious metals are non-magnetic. For gemstones, look at their clarity and brilliance under light. Fake stones often look cloudy or overly perfect.


Research the Brand

Before purchasing designer items, familiarize yourself with the brand's specific features. Legitimate brands often have identifying characteristics, such as unique serial numbers, packaging styles, or authentication cards. For example:

  • Tiffany & Co.: Known for their distinctive blue boxes and "T&CO" engraving.
  • Cartier: Often includes unique serial numbers and a certificate of authenticity.
  • Rolex Watches: Feature laser-etched logos and a high-quality sapphire crystal face.


Use Professional Testing Equipment

For those who frequently buy and sell jewelry, investing in professional testing tools can make a difference. Precious metal testing kits, diamond testers, and magnifying loops can help you identify authenticity quickly. Many pawn shops also use these tools, so don’t hesitate to request an authentication test before committing to a purchase.


Check for Tasting Notes in Second-Hand Jewelry

An often-overlooked element is the history of second-hand pieces from credible sources like pawn shops. Authentic high-value jewelry often comes with documentation or details about its origin. Many pawnbrokers include tasting notes or descriptions of the metal quality, gems, and previous owners when available.


Trust the Source

Where you shop matters. Buy from reputable businesses that have built trust over the years of operation. Experienced pawn shops often have skilled appraisers who thoroughly inspect items before selling. Additionally, they’re transparent about their jewelry’s origin, authenticity, and condition.
