Get Instant ValuationUnvault evaluates each item separately so you can understand what is driving its estimate before deciding what to sell.
Estate jewelry arrives as a mixed group rather than a single item. Value is established piece by piece: what each one is made of, what it holds, and what a buyer will pay for it now.

A box of inherited jewelry is not one lot, and pricing it as one is where value quietly disappears. Go through it item by item.
Be sure to photograph each complete piece then find the marks: 10K, 14K or 18K, or the fineness equivalents 417, 585 and 750, along with any maker’s signature, assay punch or serial number.
Clasps and findings are often a different metal from the body and are worth their own photograph. Note the damage as you go, and set aside whatever paperwork came with the estate. None of this requires you to know what anything is as it only requires that each piece is seen separately. Compare karat and fineness marks

Every piece has a metal baseline: verified purity times net weight times the metal price at a stated moment. Net is what remains once stones, clasps, springs and any filler come out, so it is rarely what a household scale reads.
That baseline is the floor. Diamonds and colored gemstones are valued on their own characteristics, a recognized signature can carry value well beyond the materials, and hand-fabricated or period work holds value a weight calculation never sees. Demand decides how much of that translates into an offer, since appetite for particular styles and for individual makers moves over time.

Estate pieces show their age, and that is expected. Worn prongs, broken clasps, missing stones and old repairs are recorded and factored in, not used to write a piece off.
Do not repair or polish anything first; the cost rarely returns in the offer, and on a period or signed piece refinishing can remove exactly what made it collectible.
Provenance helps where it can be documented, and current demand does the rest. Where an estate has several people with an interest in it, an independent estimate that itemizes each piece gives everyone the same set of facts to work from rather than competing impressions.
Note: Submit pieces as they are and decide what to sell after reviewing each estimate when dealing with a company like Unvault. Nothing obliges you to sell the whole group, or any of it.
Great service. I was nervous about shipping my jewelry but everything went smoothly. Awesome communication and fast process. Will use again!
Great company to work with easy to upload & the whole process took less than a week. For me I actually received $500 more than my estimate which was quite a surprise. I would definitely recommend & I would use this company again…
