Consultation Model

Why Every Engagement
Begins With Consultation

01

Expert Screening

Every engagement is reviewed by a GIA-certified gemologist before any formal assessment begins. The consultation confirms scope, materials, and appropriate service routing.

02

Structured Case Preparation

Prior to the appointment, your submitted materials are reviewed. This enables our experts to arrive prepared with targeted questions and a methodology framework.

03

Strategic Direction

The consultation establishes the right analytical path — whether authentication, valuation, advisory, or a combined engagement — ensuring the correct service is delivered.

04

Asset Protection Protocol

The consultation process protects clients and assets by establishing documentation, chain of custody, and confidentiality agreements before any physical or digital materials are transferred.
