Looking for a Trusted Diamond Supplier
to Source Into Australia?
Discover why jewellers, retailers, and designers across Australia are partnering with Shreeji Diamond — Bangkok’s most established natural and lab grown diamond manufacturer.
If you’re an Australian jeweller, retailer, or designer searching for a reliable diamond source — one that offers consistent quality, full certification, and pricing that actually works for your margins — you already know how hard that is to find. Shreeji Diamond was built to be exactly that partner.
What Australian Buyers Are Up Against
Sourcing diamonds in Australia is a genuine challenge. Whether you’re a boutique jeweller or a growing wholesale brand, the same frustrations come up time and again.
High Local Pricing
The Australian market carries significant mark-ups at every layer of the supply chain. By the time a stone reaches a local reseller, retail margins are squeezed — often to the point where competitive pricing becomes nearly impossible.
Limited Selection
Local suppliers often carry constrained inventory — specific shapes, sizes, or grades may be unavailable, or subject to long lead times. Custom requirements are particularly difficult to fulfil at scale domestically.
Inconsistent Quality
Without direct manufacturer relationships, quality control relies entirely on intermediaries. Matching pairs, calibrated sizes, and consistent colour runs are difficult to guarantee through multiple layers of distribution.
Certification Gaps
Not all stones available locally come with GIA, IGI, or HRD documentation. For businesses that need to demonstrate provenance and quality to end customers, this creates a credibility problem that is hard to overcome.
The smart solution? Partner directly with a verified manufacturer — one with a 30-year track record, international certifications, and the production scale to serve both boutique and wholesale needs. That’s Shreeji Diamond.

— Shreeji Diamond, Bangkok · Trusted by International Buyers Since 2000What Australian Buyers Ask Us
If you’re considering working with an offshore diamond supplier for the first time, these are the questions that matter most.
-
Can I trust the certification on stones from Shreeji Diamond?
Absolutely. All diamonds we supply are certified by GIA (Gemological Institute of America), IGI (International Gemological Institute), or HRD — the world’s three most respected independent grading laboratories. The certificate accompanies every stone, and the grade you see is the grade you get.
-
Do you have a minimum order quantity?
No — we work with individual jewellers needing a single stone as readily as wholesale buyers placing bulk orders. Our pricing scales accordingly, with better rates available for larger volume commitments.
-
How does shipping to Australia work?
We ship via insured international courier to all Australian states and territories. All shipments include insurance, tracking, and full certified documentation for customs clearance. We handle the paperwork — you just receive your stones.
-
Can I get samples before committing to a larger order?
Yes. We encourage new buyers to start with a smaller introductory order so you can assess quality firsthand. We’ll share video and photography of specific stones before any shipment, and our team is happy to walk you through the grading reports in detail.
-
Do you supply both natural and lab grown diamonds?
Yes — this is one of our key strengths. We are fully equipped to supply both natural polished diamonds and CVD lab grown diamonds across all shapes, sizes, and quality grades. Many of our buyers source both, positioning themselves for the full spectrum of Australian consumer demand.
-
Can you manufacture finished jewellery for my brand?
Yes. Beyond loose diamonds, we offer full jewellery manufacturing in 9k, 14k, and 18k gold, as well as 925 sterling silver. Private label and OEM services are available for brands who want finished pieces with their own branding.
