Responsible sourcing is a process of documented questions, supplier selection, disclosure and continuous improvement. It should not be reduced to a broad ethical slogan that cannot be supported for the specific stone or metal.
Supplier due diligence
Suppliers should be assessed for identity, business records, invoices, product knowledge, disclosure practices and willingness to provide supporting documentation. Higher-risk or unusual material may require additional review.
Natural and laboratory-grown disclosure
Natural and laboratory-grown diamonds must be clearly distinguished in product records, quotations and customer communication. The same principle applies to synthetic, treated, composite and imitation coloured stones.
Origin claims
A country or mine-origin claim should be made only where there is a documented and appropriate basis. Sri Lankan or Ceylon origin for a gemstone should not be inferred from seller location or colour alone.
Treatment and laboratory evidence
Known treatments and relevant laboratory reports should travel with the commercial record. The absence of a report must not be represented as proof of untreated status or origin.
Metals and recycled-content claims
Metal fineness should be specified. Recycled-content or chain-of-custody claims should be limited to what the supplier documentation supports and should identify whether the claim relates to the specific batch, supplier programme or general sourcing approach.
Marketing language
Terms such as ethical, conflict-free, sustainable, investment-grade or rare should be used only with context and evidence. Customer-facing claims must distinguish verified fact from supplier statement, professional opinion and aspiration.
Continuous improvement
Records, supplier performance and new guidance should be reviewed periodically. A concern may lead to additional evidence requests, suspension of a supplier or correction of customer-facing content.
Scope, written confirmations and priority
This policy explains supplier due diligence, disclosure and responsible claims at website level. It does not replace an individual quotation, order confirmation, laboratory report, return authorisation, warranty document or written exception agreed for a particular customer. When information differs, mandatory law comes first, followed by the accepted written contract and the document created for the specific transaction. General website copy is then used as supporting context. Customers should keep the latest version of every approval and ask for clarification before relying on a verbal summary. Diamond Kingdom should identify which details are confirmed, which are estimates and which depend on inspection or third-party evidence. Examples include a stone, metal, origin statement, treatment, supplier record or marketing claim. A transparent process records the decision at the point it is made rather than trying to reconstruct it after production, delivery or a dispute.
Practical customer checklist
Before taking action under this policy, record the page or order reference, the date, the customer name used for the enquiry and the outcome you are requesting. Preserve relevant messages, quotations, invoices, photographs, certificates, packaging and delivery evidence. Read the complete written specification rather than relying on a product title or social-media image. Where a deadline matters, state the exact date and explain why it is important. Where an image is supplied, confirm that you are entitled to share it and identify whether it is a visual reference or the exact item concerned. Do not send a valuable jewel, loose stone or original document until a secure route has been agreed. These steps are not intended to create an obstacle; they allow customer care to identify the correct record, assess the issue proportionately and avoid asking the customer to repeat the same history to several people.
Communication, records and reasonable response
A sourcing question should be acknowledged within a reasonable period and handled through a channel that preserves the important details. The first response may ask for missing information, explain the expected assessment route or provide an interim safety instruction. A complex matter can require a workshop inspection, carrier investigation, laboratory clarification, supplier evidence or professional advice. Diamond Kingdom should keep a concise record of the material facts, decisions and customer approvals while limiting access to people who need the information. Customers should receive an understandable explanation of the next step and any cost, timescale or limitation that can be confirmed. Automated messages and website tools support the process but do not replace a human review where the decision affects money, personal data, product identity, safety, legal rights or an approved jewellery specification.
Jurisdiction, mandatory rights and policy updates
Diamond Kingdom serves customers who may be located in different countries. Consumer, privacy, electronic-communications, customs and dispute rules can therefore depend on the contracting entity, customer status, delivery destination and way the agreement was formed. Nothing in this policy is intended to remove a right or remedy that cannot lawfully be excluded. If a local rule gives the customer greater protection, the mandatory rule applies. The website version may be updated when the service, technology, supplier process or legal framework changes. A material change does not retrospectively rewrite an accepted order unless the parties agree or the law requires it. For an active transaction, use the version and written terms supplied with that transaction and contact customer care if the website summary appears inconsistent.
