Services.
Each engagement is approached with care, clarity and long-term intent.
Collaboration
Shared Authorship
At Jangbari Jewellery Co. LLC, collaborations are conceived as shared creative territories rather than transactional projects. They begin with alignment of values, intent and perspective and unfold through dialogue rather than prescription.
We collaborate with brands, artists, designers and institutions on projects that benefit from multiple points of view. These may take the form of jewellery, objets, limited works or cultural initiatives and may exist publicly or discreetly, depending on the nature of the collaboration.
Where appropriate, collaborations may find expression through one of our existing brands. A project may naturally align with them and in other cases, work may sit independently, unbound by any single brand identity.
At all times, authorship, attribution and scope are defined deliberately. JJCo. participates as a creative and strategic partner, allowing collaborations to exist outside conventional product cycles and beyond the constraints of retail logic.
Our interest lies in projects shaped by exchange, where shared intent produces outcomes that could not exist alone.
Design and Production
Precise Execution
Jangbari Jewellery Co. LLC provides design and production support to brands, designers and industry partners across the jewellery and gemstone sector.
Our work focuses on translating ideas into viable, well-executed outcomes. We support projects at various stages, from early concept development through technical design, material selection, sourcing and production coordination.
This includes guidance on gemstones and metals, feasibility assessment, design refinement and access to trusted manufacturing and supply networks. Engagements are handled on a B2B basis and may be confidential or white-label, depending on the nature of the mandate.
We approach each project with precision, practicality and an understanding of both creative intent and production realities. The objective is not authorship or visibility, but reliability, quality and delivery.
Design and production support is structurally distinct from private bespoke creation, which is conducted exclusively through 1905 Jewels.
Advisory
Independent Judgement
Our advisory work supports collectors, estates, brands, insurers and institutions seeking clarity and professional judgement. This includes appraisals and valuations, as well as guidance on gemstones, precious metals, materials and quality considerations.
All advisory engagements are conducted with discretion and objectivity. Opinions are grounded in technical knowledge, market awareness and practical experience, and are delivered without commercial pressure or retail influence.
Where required, advisory work is clearly separated from sourcing, production or sales activities. This separation ensures credibility, transparency and trust, particularly in valuation and reference contexts.
Our role is not to persuade, but to inform, providing clients with the insight needed to understand value, assess materials, and make confident well-considered decisions.
