Problem Statement
Why Rare-Gem Investing Doesn't Scale
The market for investment-grade colored gemstones remains fragmented and inefficient, creating insurmountable barriers for institutional capital.
Closed Access to Top-Tier Supply
Consistent sourcing of the finest Investment-Grade Gemstones on the open market is impossible, as they trade exclusively through private dealer networks.
Fragile and Costly Expertise
SSEF/Gübelin/GRS certification requires booked slots, complex logistics, and a strict chain-of-custody. A single error can cost tens of thousands.
Operationally Heavy Custody
Institutional vaulting (Malca-Amit/Brink’s) and Jewelers Block insurance are complex projects with rigorous intake and inventory procedures.
No Defensible Net Asset Value (NAV)
The market is fragmented. Without systematized comparable sales and haircut rules, NAV cannot be calculated with integrity.
Near-Zero Liquidity
Exits are slow and manual, with capital locked for years and no functioning secondary market.
Illiquid Market Needs Capital
The market lacks liquidity. Gem dealers seek institutional capital but lack infrastructure for bankable packages, leaving vast opportunities untapped.
These barriers have not only kept institutional capital on the sidelines but have also prevented a willing market from accessing it, despite the asset class's strong historical performance.
Our Solution
Introducing a New Standard for On-Chain Rare Assets
GEM RWA is an end-to-end infrastructure that brings unparalleled transparency and liquidity to investment-grade gemstones by unifying the entire lifecycle under a single, secure protocol.
Asset Quality & Verification
Only investment-grade stones with top-lab certification (SSEF, Gübelin, GIA).
Institutional-Grade Custody & Security
Vaulting with Malca-Amit/Brink’s and 100% insurance coverage via Jewelers Block policy.
Provable Transparency & NAV
A transparent NAV oracle based on auction/OTC comps and a clear haircut methodology.
Managed Liquidity & Compliance
Quarterly redemption windows, organized OTC, and full compliance within the VARA framework.
This end-to-end standardization unlocks the rare gem market for institutional capital for the first time.
How It Works
The Seamless Workflow: Asset Onboarding, Valuation, and Liquidity
Our platform orchestrates a secure flow where each step—from investor onboarding to exit—is interconnected and verifiable.
Investor Onboarding & KYC/Whitelist
Qualified investors undergo a verification process to gain access to the platform.
Asset Procurement & Vaulting
The platform sources the gemstones, manages logistics, certification, and places them into institutional custody (Brink’s/Malca-Amit) with full insurance.
NAV Oracle & Valuation
The independent NAV oracle determines the value of the asset pool based on transparent methodology (comps, haircuts). This value becomes the basis for tokenization.
Token Minting
Digital tokens (ERC-3643), representing pro-rata ownership, are minted on the blockchain and distributed to whitelisted investors.
Liquidity Execution (Redemption/OTC)
Investors can close their position during scheduled quarterly redemption windows or via organized OTC trades, with the platform facilitating the settlement.
The Connecting Layer: Blockchain
Every critical action—minting, burning, NAV update—is recorded on-chain for an immutable and auditable trail.
This integrated cycle turns a once illiquid and opaque asset into a transparent, structured product with defined entry and exit points.
Fifty Years of Appreciation in Colored Gemstones
Over the three years from June 2020 to June 2023, select colored gemstones delivered 15–35% year-over-year gains—materially outperforming the S&P 500 (≈10% per year). This divergence highlights a long-term, fundamentals-driven revaluation of rare colored gems. Independent research confirms this structural shift, with record per-carat prices for top-grade stones consistently surpassing those of colorless diamonds. Despite this attractive and documented performance profile, direct investor access has historically remained limited.
Consistent appreciation.
Pigeon blood rubies (vivid red, unheated), 2-3 carats:
• +14% (2019),
• +12% (2020),
• +18% (2021),
• +24% (2022),
• +19% (2023),
Each auction season set new records.
Experts often call rubies "the most reliable investment stone."
Burma Blue Sapp, 1ct, 2.5.75, LI, no heat
Blue Sapphires
~5–10% per year on average, with a
stronger surge in recent years.
Burmese unheated sapphires (2–5 carats):
• +15% (2019),
• +16% (2020),
• +19% (2021),
• +36% (2022),
• +28% (2023).
Average ≈ 10% p.a.
Colombian Emerald, 1ct, 2.5/75, LI, no treatment
Colombian Emeralds
Colombian emeralds (investment grade, 2–5 carats):
• +50% to +150% cumulative growth over 2019–2023,
• equivalent to a 1.5× to 2.5× increase in market value.
From 2012 to 2023 the price index rose more than 11×.
Even “second tier” (greener) stones are now in demand, as collectors have been
priced out of neon blues.
Burma Spinel, 1ct., Red 2.5/75, LI
Burma Spinel
Mahenge spinel (Tanzania):
• +47% (2018),
• +51% (2019),
• +16% (2020–2021),
• +22% (2022),
• +25% (2023).
Historically far cheaper than ruby, but the gap is narrowing quickly.
By contrast, natural (colorless) diamonds have shown significant volatility. The benchmark 1-ct D-IF diamond fell ~24% in 2024 (from ~$21,000 to ~$16,000/ct), echoing earlier cycles of sharp run-ups and reversals.
Technology & Infrastructure
Institutional-Grade Infrastructure, Built on Proven Components.
Security, transparency, and compliance — achieved through audited smart contracts, institutional custody, full insurance, and on-chain governance.
Blockchain & Token Standard
ERC-3643 security tokens enable on-chain whitelisting, investor rights, and regulatory-grade transfer restrictions — designed for qualified investors.
Custody & Insurance
All gemstones to be stored with institutional vaulting providers (Brink’s / Malca-Amit), secured by 100% coverage through a Jewelers Block insurance policy.
Compliance & Governance
KYC/AML is enforced directly at the token level: all token operations - are restricted to verified investors. Protocol governance defines the rules for redemption, OTC trades, and liquidity management, ensuring compliance with institutional standards
Smart Contracts & Oracle Layer
Smart contracts are being developed with audit-readiness in mind, enforcing fund mechanics. A NAV oracle will continuously update fair value based on auction and OTC comparables with transparent haircut methodology.
Security & Audit
The infrastructure is currently being assembled and prepared for independent security audits. Each component is selected to meet institutional standards, with a focus on minimizing operational risks once launched.
Who It’s For — and How It Works in Practice
Institutional Investors
Portfolio diversification with governed liquidity. Institutions require predictability: clear redemption windows, transparent rules, and managed OTC flows. Unlike traditional gem holdings, capital allocation and exit timing are no longer uncertain — liquidity is structured and governed.
Family Offices
Long-term capital preservation in a scarce, high-performing asset. Investment-grade colored gemstones combine supply scarcity with decades of appreciation, now secured by custody, insurance, and transparent NAV — enabling intergenerational wealth protection.
Crypto-Native HNW
Physical-backed exposure without leaving the crypto ecosystem. Investors deploy stablecoins on-chain, receive RWA tokens, and gain exposure to physical gemstones in institutional custody — all without fiat conversion. Example: allocating $1M in stablecoins mints a proportional share of tokenized gemstones, fully insured and redeemable.

FAQ
What risks should investors consider?
Gemstones are subject to market cycles. Operational risks are actively mitigated via institutional custody, 100% insurance coverage, a transparent NAV oracle, and governed redemption/OTC rules. Market risk remains by design, as with any real asset, but the framework aligns with institutional risk controls.
How is NAV determined?
The NAV oracle integrates auction results, OTC trades, dealer transactions, and independent expert appraisals, applying a conservative haircut methodology. Valuations are updated on a periodic schedule and published on-chain.
Can I redeem for a physical stone?
Yes. If an investor’s pro-rata share equals the value of a specific gemstone in the pool, tokens can be burned in exchange for that stone. Delivery is managed by Brink’s with full chain-of-custody. Redemption-in-kind is subject to KYC/KYB, shipping/insurance costs, and applicable import rules. Brink’s manages delivery with full chain-of-custody.
Why gemstones, given so many other investment options?
Gemstones are a non-correlated, scarce, and under-owned asset class. Unlike equities, bonds, or real estate, investment-grade colored stones combine scarcity with portability and decades of performance. Institutions have had limited access — tokenization opens this niche for the first time.
What rights do token holders have?
Tokens represent proportional ownership of the governed pool, with rights to redemption under defined rules and continuous access to transparent reporting.
How is compliance enforced?
KYC/AML verification is required for every investor. Only verified wallets are whitelisted for holding and transferring tokens, ensuring alignment with institutional compliance.
