Singapore's diamond market

Singapore has positioned itself as the primary diamond storage and trading hub for Asia over the past two decades. The Singapore Freeport — Le Freeport — at Changi Airport is the most significant physical asset in this ecosystem: a purpose-built freeport facility offering bonded storage for high-value assets including diamonds, art, precious metals, and wine. Diamonds stored at Le Freeport remain outside Singapore's customs territory, which means they are not subject to GST while stored, and can be traded and transferred without triggering import duties.

Singapore's Investment Precious Metals (IPM) scheme provides an additional structural advantage: qualifying investment diamonds are exempt from GST on import and sale. The Singapore Gem and Jewellery Council (SGJC) provides the institutional framework for grading standards, trade membership, and dispute resolution — giving Singapore a compliance infrastructure comparable to Antwerp's, though with a different commercial emphasis (trading and wealth storage rather than manufacturing and cutting).

Singapore's proximity to the Indian manufacturing corridor — Mumbai and Surat, where the majority of the world's rough diamonds are cut — makes it a natural transit and decision point. Rough diamonds en route from African producing countries to Indian manufacturers can pass through Singapore Freeport, be inspected and valued by Singapore-based buyers, and onward-shipped to India without triggering GST. This logistical advantage is well understood by the 120-plus single family offices that had established Singapore operations as of 2025, many of which hold significant gemstone positions as part of diversified alternative asset allocations.

What Singapore buyers acquire

Singapore's diamond buyers divide into three broad categories. The first is the family office investor — typically a Southeast Asian or Northeast Asian HNWI who holds exceptional single gems as a portable store of value. The profile is stones above 5 carats, D–F colour, VVS or better clarity, GIA-certified, stored at Singapore Freeport. These buyers are price-sensitive in the sense that they are informed — they understand GIA reports and polished market prices — but they are not volume-driven. They are seeking access to exceptional material that is not readily available through Singapore's retail and auction market.

The second category is the private bank client serviced by Singapore's wealth management infrastructure: DBS Private Bank, UBS Singapore, Julius Baer, and Pictet, among others. These institutions increasingly offer gemstone-linked structured products and direct stone acquisition as part of alternative investment mandates. The underlying demand is for GIA-certified polished stones with clear provenance and transparent market pricing.

The third category is the jewellery trade — regional manufacturers and retailers who source polished parcels from Singapore as an alternative to buying directly from Antwerp or Mumbai. For this buyer, the Singapore Freeport is a convenience: inspect and acquire without import costs, then import for manufacturing or sale when ready.

African rough to Singapore

Rough diamonds from African producing countries can be airfreighted directly to Singapore via Changi Airport. The logistics chain is well-established: specialist carriers including Brinks and Malca-Amit operate Singapore offices with Changi-based handling infrastructure. Rough arriving at Changi under bonded transit arrangements enters Singapore Freeport without triggering import GST, and can be inspected, valued, and traded within the freeport environment.

For sellers shipping from Botswana, Angola, or Sierra Leone, the Kimberley Process certificate must travel with the parcel. Singapore is a KP participating country; its KP authority (administered by Enterprise Singapore and the Singapore Customs) issues import receipts on arrival and verifies the accompanying KP documentation. A Singapore-based valuer or the SGJC can provide independent assessment within the freeport for buyers who require it before committing.

The combination of zero-GST transit, world-class carrier infrastructure at Changi, Singapore Freeport storage, and a sophisticated buyer community makes Singapore an increasingly competitive alternative to routing African rough directly to Antwerp or Mumbai. For sellers whose buyers are concentrated in Asia, Singapore is the natural entry point.
