Sourcing & certification
Where the Stones Come From
A diamond is only as good as its paperwork and its origin. This page sets out where STIG Inter PH Inc. stones come from, who inspects them, and which frameworks govern the trade around them.
Only conflict-free diamonds
The Kimberley Process is an international certification system that prevents the trade in conflict diamonds. Every STIG Inter PH Inc. stone is fully traceable and comes from responsibly certified sources.
The Kimberley Process governs rough diamond trade between participating countries. It is a sourcing safeguard, not a quality grade.
From source to sealed stone
Each step leaves a document behind, and each document names the stone it belongs to.
Responsibly sourced
Stones originate from suppliers operating under the Kimberley Process, in participating markets.
Independently graded
Eligible diamonds carry GIA certification recording carat, cut, colour and clarity, with a report number you can verify yourself.
Traded under DMCC rules
Trade and logistics run through the Dubai Multi Commodities Centre framework, the region's regulated commodities authority.
Stored under SIRA oversight
Storage and security arrangements fall under the Security Industry Regulatory Agency's licensing regime.
The bodies involved
Four independent organisations touch the process. None of them endorses STIG Inter PH Inc., and none guarantees a price — each one governs a specific part of the chain.
- GIA
- Gemological Institute of America — independent diamond grading
- Kimberley Process
- International conflict-free sourcing certification
- DMCC
- Dubai Multi Commodities Centre — trade and logistics framework
- SIRA
- Security Industry Regulatory Agency — storage and security licensing
Verify it yourself
Never take a certificate on trust because someone showed it to you. Check the report number on GIA's own Report Check service, reached by typing gia.edu into your browser — not through a link that was sent to you.
What these frameworks do and do not mean
Certification and regulatory oversight describe origin, characteristics, and the rules governing trade and storage. They are not a valuation, a guarantee of resale price, or an endorsement of any seller. STIG Inter PH Inc. is not a financial product; it concerns natural diamonds as tangible assets.
