Why You Need an Appraisal
Documentation is the difference between an heirloom and a guess.
A professional appraisal establishes the existence, condition, and fair value of your property — accepted by insurers, courts, and the IRS.
Insurance
Protect what you own
An appraisal documents the existence, condition, and replacement value of your belongings — the foundation of any luxury insurance policy.
Estate
Settle with certainty
A taxable estate requires efficient cataloging of property with an appraisal that meets IRS requirements.
Divorce
Divide with fairness
An appraisal establishes fair value, enabling the equal distribution of property both parties can trust.
Donation
Give with documentation
Recommended for charitable donations over $1,000 — and required by the IRS for anything above $5,000.
Authentication Services
A $500 billion market runs on trust.
The pre-owned luxury industry is projected to reach $500B by 2030. Protect your investments with proper verification — before and after every sale.
When Selling
Trust sells
Verified, authentic items command higher prices on the secondary market. Documentation from a recognized authority turns hesitation into confidence.
When Buying
Protect yourself
Only with documentation that an item is counterfeit can you recoup losses on a fraudulent sale. Better yet — have the item authenticated before you purchase.
Business Services
For resale platforms
We help resale companies achieve the best possible selling prices through identification, authentication, and valuation. Fast turnaround, competitive rates.
Brand Protection Services
When authenticity is contested, evidence decides.
For brands, legal teams, and platforms defending their intellectual property — from discreet field work to laboratory analysis, every finding is documented to trial standard.
Investigations
Discreet, evidence-grade inquiry
Confidential investigations into counterfeit sales, gray-market distribution, and IP infringement — documented to a standard suitable for legal action.
Secret Shopping
Anonymous test purchases
Covert acquisitions from suspect sellers and platforms to secure product evidence, verify sales practices, and establish chain of custody.
Dissection
Physical deconstruction
Systematic teardown of suspect goods — construction, materials, and hardware compared point-by-point against authentic references.
Scientific Testing
Laboratory analysis
Objective materials testing of leathers, metals, and textiles — producing court-ready findings that stand up to scrutiny.
