STIG International.
The real source.

Diamond Strategist is an affiliate programme of STIG International Trading FZCO — a licensed diamond trading company headquartered in Dubai Silicon Oasis, one of the world’s premier diamond trading hubs. STIG operates inside the global diamond supply chain, not outside it.

Since 2014, STIG has sourced rough diamonds directly from mines in Africa and Australia, had them cut and graded by independent laboratories including IGI and HRD Antwerp, and sold certified stones to collectors and investors across 23 countries.

By accessing diamonds through STIG’s partner programme, you benefit from institutional-grade sourcing at a price point that retail buyers never see.

From mine to your
dashboard in 4 steps.

STIG’s supply chain removes every middleman between the earth and your account. Here’s exactly what happens.

01

Create free account

No credit card. No commitment. Explore the dashboard, review diamonds in STIG’s inventory, and understand the programme fully before deciding.

02

Mine-direct sourcing

STIG purchases rough diamonds directly from licensed mining operations in Africa and Australia — bypassing the 5-tier retail chain that inflates prices up to 400%.

03

Cut & independently certified

Every stone is cut, polished and submitted to IGI or HRD Antwerp for independent grading. Each diamond receives a certificate, 4C assessment, and laser inscription.

04

Monthly credits + choice

Your plan generates monthly credits throughout the 12-month term. At end of term: take physical delivery of your certified diamonds, or sell back at market value.

diamond market works.

Diamond market overview · STIG International · ~4 minutes

Your cash depreciates.
Diamonds do not.

The US dollar has lost over 96% of its purchasing power since the Federal Reserve was founded. Savings accounts rarely outpace inflation. Certified diamonds are a globally portable, physically compact, universally recognised store of value that has appreciated consistently over decades.

🛡

Tangible, crisis-proof ownership

You own a physical asset with a unique certificate number. It cannot be inflated away, frozen by a bank, or zeroed by a market crash.

💎

Maximum value in minimum space

A 3-carat diamond worth $100,000+ fits in a coat pocket. No storage infrastructure, no custody fees, no logistics complexity.

📉

Shrinking supply, stable demand

Global mine output peaked in 2005 and has declined. New discoveries are rare. Demand from Asia continues to grow. The supply-demand equation favours long-term value.

Why can we offer these returns?
Here’s the exact math.

This is the question most investment pages avoid. We answer it directly, because your confidence requires it.

Mine

Rough purchase

STIG buys rough diamonds at mine-gate price. No broker. No dealer. No retailer margin yet.

Cut

Polishing & grading

Cost of cutting + IGI/HRD certification is absorbed. This is STIG’s core operating expense.

Sell

Certified retail sale

Certified diamonds sell at 3–5× the mine cost. This margin is the economic engine of the programme.

Share

Member credits paid

A portion of that margin is shared back with members as monthly plan credits.

The margin between mine price and certified retail price is what makes monthly credits possible.

Traditional diamond retail involves a miner, rough dealer, cutter, polisher, wholesaler, importer, and retailer — each taking a margin. By the time a diamond reaches a high-street jeweller, the consumer price is typically 4–6× the original mine value.

STIG operates at stage one of that chain. The margin between what STIG paid and what the market pays is substantial — and that margin creates room to reward partners and members.

Monthly plan credits come from this operational margin, not from investment speculation. STIG sells real diamonds to real buyers. That is the revenue base.

Real feedback from STIG International’s verified member base across 23 countries.

As a collector and investor, I always look for premium-grade diamonds. STIG International provides exactly that — authentic, well-graded stones at competitive prices. The customer service was excellent, making the entire experience smooth and trustworthy.

Buying loose diamonds online can be challenging, but STIG International made it easy with detailed certificates and transparent pricing. The diamonds exceeded my expectations in both quality and value. I will definitely be purchasing again.

I was amazed by the quality of the diamonds I received from STIG International. The brilliance and clarity are exactly as described, and the certification gave me full confidence in my purchase. A truly reliable source for high-quality loose diamonds.

The transparency STIG offers is what sold me. I could verify every certificate number independently through IGI’s own database. That level of accountability is rare in this space. My first plan ran to completion without a single issue.

I started with SP2 at $1,500 to test the water. Twelve months later I renewed at SP4. The monthly credits arrived on schedule every single month, and the certificate tracking on the dashboard is genuinely impressive. Highly recommended.

After 15 years in private equity I thought I’d seen every alternative investment structure. Diamond Strategist via STIG is genuinely different — physical asset backing with a clear, honest explanation of where the returns come from.

STIG International Trading FZCO is a licensed diamond trading company registered in Dubai Silicon Oasis (DDP Building A2, Dubai, UAE). They have operated in the diamond supply chain since 2014, sourcing rough diamonds directly from mining operations and selling certified finished stones to collectors and investors across 23 countries. Diamond Strategist is an affiliate partner programme of STIG — not a separate company.
The returns are funded by the margin between STIG’s mine-level acquisition cost and the certified retail market price. Rough diamonds sourced directly from mines cost a fraction of what the same stone commands once cut, polished, and certified by IGI or HRD. STIG’s business is built on monetising this margin. Member plan credits are a share of that margin, not returns from financial speculation or leverage. All projections are illustrative and past performance does not guarantee future returns.
STIG’s diamonds are certified by IGI (International Gemological Institute) and HRD Antwerp. Every certificate contains a unique report number, full 4C grading, symmetry and polish grades, and a laser-inscribed ID on the stone’s girdle. Certificate numbers can be independently verified on the relevant lab’s website.
At the end of your 12-month plan term, you have two options: take physical delivery of your allocated certified diamond(s), shipped securely and insured; or elect to sell the diamonds back at the prevailing market price at that time. Some plans also offer renewal at current rates.
Diamonds are held in professional-grade secure vaulting through Brink’s, the world’s leading secure logistics company. Storage is insured through Lloyd’s of London. You can track the status of your allocated stone via your member dashboard throughout the plan period.
Yes. Creating your account costs nothing and requires no payment details. You can browse STIG’s current diamond inventory, review all plan options, use the calculator, and read all documentation before deciding to proceed. The minimum to start a plan is $100 for SP1.
No. Diamond Strategist is a physical diamond ownership and partner programme. It is not a regulated investment product and does not constitute financial advice. All return projections are illustrative based on plan terms — they are not guaranteed. We strongly recommend consulting a qualified financial adviser before committing significant capital.
VIP packages are optional add-ons purchased at plan activation. VIP +1% ($150), VIP +2% ($500), and VIP +3% ($1,000) each increase your monthly plan credit rate by the stated percentage for the entire 12-month duration. The calculator on this page shows the exact figures for your chosen amount.
SP (Solution Plan) tiers range from SP1 ($100 minimum) to SP5 ($10,000 minimum) and are designed for individual investors. BD (Big Diamond) tiers — BD6 and BD7 — start at $50,000 and $100,000 respectively and are aimed at high-net-worth individuals seeking larger certified stone allocations with the highest monthly credit rates (3.2%–3.3%).
Upon plan activation, a certified diamond from STIG’s inventory is allocated to your account, matched to your plan tier. Your dashboard shows the exact stone assigned: certificate number, full 4C grading, and IGI or HRD report. You can independently verify this certificate on the grading lab’s website at any time.
Yes. Members can hold multiple active plans simultaneously. Each plan runs independently with its own diamond allocation, certificate, and 12-month term. Your dashboard consolidates all active plans in a single view.
Diamond Strategist accepts bank transfers, major credit and debit cards, and select cryptocurrency payments depending on your region. All transactions are processed through PCI-compliant infrastructure.
Plans are structured as 12-month commitments. Early exit options vary by plan tier and are outlined in your plan agreement at the time of activation. We recommend reviewing the full terms before committing.
If you elect to take physical delivery at end of term, STIG arranges insured shipment via Brink’s secure logistics directly to your specified address. The stone arrives with its original certification documentation in a tamper-evident sealed package. Import duties applicable to your jurisdiction are your responsibility.
If you elect the sell-back option at end of term, STIG repurchases the allocated diamond at the prevailing wholesale market price at that time, referenced against published indices such as Rapaport. This price is determined at the point of sell-back election. The sell-back option is not a guaranteed fixed-price buyback.
STIG International Trading FZCO is registered with the Dubai Silicon Oasis Authority (DSOA) in the UAE. You can verify their registration through the DSOA public company registry. Their address — DDP Building A2, Dubai Silicon Oasis — is a physical, verifiable location.
Yes. All diamonds held in STIG’s allocated vault storage are covered by insurance through Lloyd’s of London throughout the plan term while the stones are in Brink’s vaulted custody.
Diamond Strategist is available to members in 23+ countries across Europe, Asia, the Middle East, and the Americas. Creating a free account confirms your eligibility before any commitment is required.
Certified diamond values are tracked against the Rapaport Diamond Report and IDEX Online Diamond Index, which publish weekly wholesale price benchmarks by shape, carat, colour, and clarity. STIG uses these benchmarks to determine sell-back pricing.
All members have access to the support team via email and in-dashboard messaging throughout their plan term. SP-tier members receive standard response times (typically within 24 hours). BD-tier members receive priority support with a dedicated account manager.
