Beauty should never come at the cost of responsibility.

We are committed to sourcing natural diamonds and gemstones from trusted, compliant suppliers who follow internationally accepted ethical and legal standards. Our partners adhere to responsible mining and trading practices, ensuring transparency throughout the supply chain.

Gold used in our jewellery is carefully selected and refined through regulated channels. We continuously evaluate our sourcing partners to maintain standards that align with our values — fairness, accountability, and respect for people and resources.

Ethical sourcing is not a claim for us; it is an ongoing responsibility we take seriously.3

Every Trinity piece is tested, not assumed.

Before reaching you, each jewel undergoes:

  • material purity checks

  • stone setting security inspection

  • finish and polish evaluation

  • wearability assessment

This process ensures that what you receive is not only visually refined but also structurally sound for your wear.

What you can rely on

How we work with retailers, designers and private-label brands.

  • Quality control

    Every finished piece is inspected under magnification before it leaves our atelier, checking stone security, prongs, surface finish and dimensions against your specification.

  • Gold purity

    Every piece is hallmarked to karat, in 9kt, 14kt or 18kt gold. We do not produce vermeil, plated or filled pieces.

  • Sourcing

    Natural diamonds and gemstones come from trusted, compliant suppliers. GIA and IGI certification is available for natural diamonds above 0.30ct.

  • NDA and confidentiality

    We are happy to sign an NDA before you share detailed designs, CAD work or specifications. Client designs and order details are treated as strictly confidential.

  • Timelines

    From design approval: 2–4 weeks for regular gemstone and diamond pieces, and up to 8 weeks for invisible-set and pie-cut pieces.

  • If it's not right

    If a piece does not meet the agreed specification on delivery, we remake it at no cost.

  • Shipping

    Orders ship fully insured with tracking. Typical transit is 3–5 days to the USA and Europe, 2–3 days to the Middle East and 1–3 days within Asia.

  • Payment

    New trade orders are prepaid by international bank transfer. Other arrangements can be discussed for larger orders and established partnerships.
