When you buy a designer ring, it should come with a certificate of authenticity proving the metal and gemstone quality, a detailed appraisal for insurance, and the original receipt. You might also get a warranty card covering repairs, a care guide, and the designer's hallmark or signature. Keep these in a safe place; they protect your investment and prove the ring's provenance if you ever sell or insure it.
