Elmonas manufactures lab-grown diamonds at its own benches in Surat and supplies Singapore's wholesale trade in three parcel bands: trial orders under 15 ct for account opening and qualification, mid parcels of 15–50 ct for established replenishment programmes, and bulk parcels above 50 ct for manufacturing programmes and distribution accounts. Every parcel is quoted in USD/ct and SGD/ct. IGI or GIA certification is included per stone. First orders are supported by CAD or letter-of-credit terms.
PARCEL BANDS
Each band is priced on a per-carat basis in USD and SGD. Pricing is parcel-specific and communicated on a per-enquiry basis; send your specification and we return a firm quote with the applicable per-carat rate and total parcel cost.
Designed for account opening and specification verification. A trial parcel lets you inspect stones against the certificate before committing to a standing programme. CAD and LC at sight are available. Quoted per carat in USD/ct and SGD/ct.
For established accounts running a regular replenishment cycle. Parcels are built to specification (shape, colour, clarity, and cut grade) and dispatched on an agreed cadence. Per-carat pricing reflects the mid-band volume.
For manufacturing programmes, distribution accounts, and buyers with predictable weekly or monthly volume. Bulk parcels are priced on a per-carat basis specific to the parcel composition. Contact us with the specification to receive a bulk-band quote.

SINGAPORE LANDED COST
Singapore levies 9% GST calculated on CIF value plus duties and incidental charges. Loose diamonds are not a dutiable category under Singapore Customs, so the applicable rate is 0% customs duty plus 9% import GST. A GST-registered Singapore buyer can typically claim the import GST as input tax, reducing the effective landed cost to the stone price plus logistics and clearance fees in most circumstances. Confirm your buyer's GST registration status and the applicable HS classification with a Singapore customs broker before the first shipment.
A Free Trade Zone or licensed Zero-GST warehouse can suspend GST while goods remain under the relevant scheme. GST becomes payable when goods are released for local circulation. This makes Singapore a practical logistics point for buyers consolidating stock for onward export, but it does not convert a domestic sale to a Singapore jeweller into a tax-free transaction.

PAYMENT TERMS
For a first cross-border order with a new supplier, the most straightforward structures are cash against documents (CAD) and letter of credit at sight (LC at sight). Both give the buyer documentary control before funds are released while giving the supplier confirmed payment before the parcel is delivered. After a buyer has verified the company and certificates on a first order, we offer 50% pre-dispatch with the balance due before dispatch of the confirmed parcel. For small trial orders from an established contact, telegraphic transfer in advance removes the documentary overhead and is the simplest route for parcels under a defined value threshold.
Memo and consignment are not offered as a default. The stones are high-value and the dispute risk without a robust inspection protocol on both sides is significant. If a specific arrangement is required for your account structure, raise it in your enquiry and we will advise on what we can support.
