Our Guiding Principles
The Maihan Philosophy
We don't just trade assets — we architect legacies. Our philosophy is the invisible thread that connects every decision we make.
A Self-Reinforcing Ecosystem of Value
The Maihan Universe is an interconnected ecosystem where each business unit strengthens the others. Our gemstone trading generates real-world price intelligence that sharpens our investment advisory. Our precious metals expertise enriches portfolio construction. Our global partnerships open doors that no single division could unlock alone.
This is not a portfolio of separate businesses — it is a living, breathing value engine, each part amplifying the whole. At its centre lies a singular conviction: that the rarest things in the world deserve the most rigorous stewardship.
Assets that transcend economic cycles and preserve generational wealth.
Every insight from one unit enhances the decisions of every other.
Every client interaction is governed by clarity, integrity, and honesty.
Rarity Over Volume
We will never compromise the exclusivity of our offering for short-term scale. Every asset we curate is chosen because it represents the finest of its kind — not the most abundant.
Integrity Without Exception
Our word is our bond. From first contact to final delivery, every commitment we make is honoured — because trust, once broken, cannot be restored.
Long-Term Thinking
We build for decades, not quarters. Our advisory strategies, our client relationships, and our asset selections are all designed to endure through economic cycles and market shifts.
Protection of Capital
Before growth, we think about protection. Preserving the wealth entrusted to us is our first obligation — returns are the reward of doing that well.
Protecting What Matters
Risk Management
At Maihan Group, risk management is not a department — it is a discipline embedded into every decision we make, every asset we curate, and every portfolio we advise.
Asset Diversification
We structure client portfolios across multiple tangible asset classes — gemstones, gold, silver, platinum, and palladium — ensuring no single market event can undermine overall position value.
Due Diligence Protocol
Every asset undergoes a rigorous five-stage verification process: origin authentication, lab grading, market benchmarking, provenance documentation, and independent third-party appraisal before acquisition.
Market Exposure Limits
Our advisors apply strict allocation limits per asset class, geography, and counterparty to prevent concentration risk. No single exposure exceeds defined thresholds within managed portfolios.
Secure Custody & Logistics
We partner with insured, internationally accredited vaulting and logistics providers — ensuring physical assets are protected at every stage of storage, transit, and transfer.
Regulatory Compliance
All trading and advisory activities are conducted in full compliance with applicable regulatory frameworks across UAE and relevant international jurisdictions — with complete documentation.
Continuous Monitoring
Portfolio positions are reviewed on a rolling basis against real-time market intelligence. Advisors proactively communicate any material developments and adjust strategies accordingly.
Advanced Investment Intelligence
Hedging & Arbitrage Strategies
We deploy time-tested institutional strategies to protect capital, exploit market inefficiencies, and build sustainable alpha for our clients.
Capital Preservation Through Strategic Hedging
Hedging within tangible-asset portfolios is the art of structuring positions so that adverse price movements in one asset are offset — or more than offset — by gains in another. Maihan Group's advisory team deploys these institutional-grade strategies for HNW clients.
Long / Short Commodity Positioning
Simultaneously holding long positions in undervalued tangible assets while taking short exposure on overpriced correlated assets — locking in spread returns while limiting directional risk.
Gold as a Currency Hedge
Allocating a defined percentage of client portfolios into physical gold and gold-linked instruments as a structural hedge against fiat currency devaluation and inflationary monetary policy.
Rare Gemstone as Wealth Insurance
Investment-grade coloured gemstones — particularly unheated Burma rubies, Kashmir sapphires, and Colombian emeralds — have demonstrated consistent appreciation independent of financial market cycles, serving as non-correlated wealth insurance.
Geographic Diversification
Sourcing assets across multiple geopolitical jurisdictions — Burma, Sri Lanka, Colombia, Madagascar, Brazil — ensures supply-side resilience and mitigates country-specific risk premiums.
Palladium / Platinum Substitution
Exploiting industrial demand shifts between platinum group metals — particularly when automotive and industrial catalysis demand drives divergence in palladium and platinum pricing — for portfolio rebalancing.
Tangible-to-Liquid Asset Balancing
Maintaining a structured ratio between illiquid hard assets (gemstones, physical metals) and more liquid positions to ensure clients retain capital access without sacrificing long-term appreciation.
Generating Alpha Through Market Inefficiencies
The global gemstone and precious metals markets are fragmented across geographies, creating persistent pricing inefficiencies that Maihan Group's network is uniquely positioned to exploit. These strategies generate returns by identifying and capturing the spread between markets.
Cross-Market Price Arbitrage
Gemstone prices can vary significantly between Dubai, Hong Kong, and Geneva. Our broker network allows us to buy at wholesale in one market and place at premium in another — capturing the geographic spread.
Certification Arbitrage
An unheated ruby with a GIA certificate commands a dramatically different premium to the same stone with a less-recognised certificate. Our lab relationships allow us to identify under-graded stones and realise value through re-certification.
Auction vs. Private Sale Spread
Major auction houses (Sotheby's, Christie's, Bonhams) apply significant buyer's premiums. Acquiring comparable stones through private networks and selling into auction channels generates meaningful spread for sophisticated investors.
Temporal Arbitrage
Acquiring assets during periods of macro uncertainty (when liquidity-constrained sellers accept discounts) and holding through to market normalisation — a patient, conviction-based form of value capture.
Treatment-Status Arbitrage
The price differential between heated and unheated coloured gemstones can exceed 300%. By sourcing unheated stones from origin markets where this distinction is less understood, and placing them with educated collectors, we capture substantial rarity premiums.
Institutional vs. Retail Spread
Sourcing at institutional wholesale rates through our direct mine and refinery relationships, and placing with private collectors and family offices at retail premiums, provides a consistent and reliable spread across all commodity types.

Client Voices
Words From Our Clients
The trust of our clients is our most precious asset. Their words reflect the standard we hold ourselves to.
"Maihan Group's investment advisory team helped us reallocate a significant portion of our family office's liquid assets into a curated portfolio of unheated Burma rubies and gold. The ROI and the level of discretion exceeded every expectation. This is a team that genuinely understands both the asset class and the client."
"We have been sourcing paraiba tourmalines and Kashmir sapphires through Maihan for over a year. Their provenance documentation is impeccable, their pricing is transparent, and their knowledge of the global gemstone market is unmatched. They are our go-to partner for high-value acquisitions."
"What distinguishes Maihan Group is the founder involvement. Nasser and his team are personally accessible at every stage of the transaction. In a market where trust is everything, that personal accountability is extraordinary. Our physical gold position has been a cornerstone of our portfolio through significant volatility."
"The hedging strategy Maihan's advisory team constructed for us — combining unheated coloured stones with a gold overlay position — performed remarkably during the currency turbulence of 2024. Their understanding of cross-market dynamics is genuinely institutional-grade. Highly recommended for sophisticated investors."
"Maihan sourced a Colombian emerald collection for our new high-jewellery line that simply could not be found through traditional wholesale channels. The certification, the origin verification, and the speed of delivery were all outstanding. They understand the jewellery industry at the highest level."
