After purchasing a diamond, one key question arises for many buyers: how is the stone safely stored? Unlike shares or fund units, a diamond is a physical, tangible asset — professional custody and complete documentation are therefore essential.
Certified origin as the starting point
Every diamond needs a recognized certificate (e.g. from the GIA) that clearly documents characteristics such as cut, color, clarity and carat. This certificate is the foundation for all later traceability — without it, a stone can neither be clearly identified nor assessed.
Professional vault storage
Diamonds are kept in certified, high-security vault facilities specifically designed for gemstones and valuables — with corresponding access controls, insurance and monitoring.
Complete documentation
Purchase contract, certificate and invoice together form the proof of ownership and origin. These documents should be kept permanently and traceably — both digitally and physically.
Why this matters for STIG GROUP buyers
At STIG ROCK, buyers receive a purchase contract, invoice and GIA certificate from day one — combined with certified storage. This creates a clear, traceable structure for the entire ownership process.
