THE PRIVATE RESERVE · RAW GEMSTONE AND METALS
Frequently Asked Questions
A private guide to provenance, identification and verification.
A Private Reserve material is a rough gemstone, platinum-group specimen or selected lot personally chosen for its character, physical presence and documentary potential. This is not a mass-market catalogue. Each entry is treated as an individual material record with its own identity, visual archive and history.
The certificate records the identity and declared characteristics of the material inspected by The Private Reserve Raw Gemstone and Metals. It may include the material type, Stone ID or Lot ID, weight, dimensions, appearance, declared origin, treatment status, inspection date, photograph and certificate version. Unless an independent laboratory report is expressly attached, it is not a laboratory grading report and does not replace independent gemological, assaying, provenance, customs or legal documentation.
A Stone ID is the permanent identity of one individual stone or specimen. It is assigned once, retained throughout the material’s history and never reused, even if the stone is sold, transferred, returned, cancelled or removed from public display.
Example: PR-RG-DIA-260824-0001
A Lot ID identifies a commercial batch or a group of related materials. One lot may contain several individual stones, and each of those stones may also have its own Stone ID. This distinction allows a private office, collector or buyer to understand both the individual material and the wider commercial grouping to which it belongs.
Example: PR-RG-LT-DIA-260824-0001
A certificate is a dated snapshot of the registry. If a permitted correction or update is required, the material’s Stone ID or Lot ID remains unchanged, while the certificate receives a new version such as V02 or V03. Earlier versions are retained in the record history rather than silently replaced.
The QR code leads to the controlled verification page for the relevant Stone ID or Lot ID:

The page can show the approved public identity of the material, its current status, registration date, selected characteristics, approved image and available certificate version. Private commercial information, ownership details, pricing and internal notes remain restricted.
A successful verification means that the identifier corresponds to an existing registry entry and that the displayed certificate or public record matches the approved record held by The Private Reserve. It confirms the integrity of the digital record. It does not, by itself, establish an independent laboratory grade, market value, legal title, origin or unrestricted right to export or import the material.
After a certificate is approved, the system can calculate a cryptographic hash — a unique digital fingerprint of the approved record and certificate version. The hash, identifier and timestamp may then be registered on a blockchain. The certificate itself does not need to be placed publicly on the blockchain. Sensitive information remains within the controlled registry, while the blockchain provides an independent timestamped reference for the integrity of the digital record.
Blockchain verification confirms that a specific digital record or certificate version corresponds to the hash registered at a particular time. It helps demonstrate continuity, timestamping and resistance to unnoticed alteration. It does not replace physical examination, gemological documentation, provenance records, export documentation or legal review.
No. Blockchain records the integrity of the digital information submitted to it; it does not independently examine the physical material or verify every statement contained in the record. Claims concerning natural origin, geographic provenance, treatment, ethical sourcing, conflict-free status, grade or investment quality should be made only when supported by appropriate independent reports and documentation.
That depends on the specific entry. The certificate distinguishes between information personally recorded, information declared by a source and information independently verified by a laboratory or qualified specialist. Where independent verification has not been completed, the record uses precise wording such as “Declared origin” or “Treatment status not independently verified.”
Yes. For significant acquisitions, an independent gemological, assaying, provenance or legal review may be recommended before the material is acquired, transported or placed into a collection. The appropriate level of examination depends on the material, its declared origin, its intended destination and the nature of the transaction.
Where practical, selected materials may be made available for private examination. The process, location, security arrangements and delivery route are agreed individually with the client or authorised representative. The purpose is to allow the material to be considered with the level of time, discretion and attention appropriate to a serious private acquisition.
International delivery may be arranged through an established carrier such as DHL, subject to applicable export, import, customs, carrier and destination-country requirements. Before dispatch, the material is matched to its Stone ID or Lot ID, photographed, weighed where appropriate, securely packed and accompanied by the supporting documentation available for that shipment. Duties, taxes, permits, inspections and destination-country requirements remain subject to the relevant laws and responsibilities of the parties involved.
No responsible private reserve should promise to bypass customs or guarantee a particular clearance time. Customs decisions depend on the destination country, material classification, documentation, permits, inspections, duties and carrier procedures. What we can provide is a properly identified and documented shipment, transparent communication, a traceable dispatch record and coordination with the carrier or an appropriately licensed customs broker where required.
The public verification page is designed to reveal only the information necessary to establish the identity and status of the record. Pricing, ownership details, private correspondence, internal notes and confidential commercial documents are not displayed publicly unless expressly authorised.
The physical identity remains in the registry. The Stone ID or Lot ID is not deleted or reused. The public record may change status to Sold, Transferred, Reserved, Suspended or another appropriate designation while retaining the relevant history.
The certificate may be marked Cancelled or Superseded, but its historical record is not silently erased. A replacement certificate, if issued, receives a new version number and retains a clear relationship to the original document.
Send the Stone ID, Lot ID or a description of the material that has caught your attention. We will confirm availability, provide the relevant public or private record, clarify the available documentation and outline the most appropriate examination and delivery route.
“The Private Reserve is designed for clients who value provenance, discretion and precision over volume. Each material is handled as an object with a history, not merely as a line in a catalogue.”
