Tranche operates as the institutional settlement layer for certified diamond transactions originating from or destined for Samarinda, offering escrow-backed settlement, GIA/IGI/HRD certification verification, and bank-to-bank wire completion for qualified buyers and sellers.
The physical diamond market in Indonesia relies on a network of licensed dealers, auction houses, and financial intermediaries who require a trusted counterparty for high-value stone transactions. Samarinda sellers working through Tranche benefit from access to a verified international buyer pool — without the opacity and risk of unstructured peer-to-peer diamond sales. Every transaction is documented, the stone's certification is verified, and funds move only upon satisfaction of all agreed conditions.
Tranche facilitates diamonds ranging from investment-grade loose stones (D–F colour, VVS1–VS1 clarity, Excellent cut, 1ct+) to larger fancy colour diamonds and institutional-size parcels. Stones are GIA, IGI, or HRD certified. Settlement is via bank-to-bank wire or escrow; Tranche does not take custody of the stones.

Frequently Asked Questions
- How do I sell my diamond through Tranche?
- Contact our concierge via WhatsApp with your stone's certification details (GIA report number, carat, colour, clarity, cut). We'll match you with qualified institutional buyers in Samarinda and globally, agree settlement terms, and facilitate the transaction through escrow or bank-to-bank wire.
- What types of diamonds do buyers want?
- Institutional buyers through Tranche seek GIA, IGI, or HRD certified stones — particularly colourless (D–F) diamonds of VVS1–VS1 clarity, 1ct and above. Fancy colour diamonds (pink, blue, yellow, green) and quality loose stones are also in high demand. Diamond jewellery with certified centre stones is also considered.
- How long does the sale process take?
- Initial matching typically takes 2–5 business days. Once a buyer is confirmed, certification verification and settlement can complete within 5–10 business days depending on jurisdiction and logistics. Tranche concierge manages the full timeline.
- Do I need a GIA certificate to sell my diamond?
- GIA, IGI, or HRD certification significantly accelerates the sale and maximises price. Uncertified stones can be submitted for grading before listing — our concierge can advise on the fastest pathway. We do not facilitate institutional sales of completely undocumented stones.
- Is my information kept confidential?
- Tranche maintains strict confidentiality for all principals. HNWI sellers are never exposed to buyers without prior consent. Our concierge-led model ensures your transaction is handled with the same discretion as a private banking engagement.
