Noga Gemstone Advisory
The Most Natural Investment.
Noga Gemstone Advisory facilitates the acquisition of investment-grade gemstones for high-net-worth individuals, family offices, and wealth managers.
Through our exclusive network of advisors located in New York, Antwerp, Geneva, and Tel Aviv, we provide access to exceptional stones with verified provenance and significant appreciation potential.
The Problem
The gemstone market is fragmented and unregulated. Thousands of dealers operate globally, pricing is non-standardized, treatment disclosure varies widely, and quality assessment requires specialized expertise. Without deep market knowledge and trusted relationships, buyers risk overpaying, receiving misrepresented stones, or working with unreliable sources.
The Solution
Noga serves as your trusted expert in this complex market. We handle the entire sourcing and verification process — evaluating quality, negotiating pricing, confirming authenticity, and ensuring proper documentation — so you can acquire exceptional gemstones with confidence.
The Value
Like a wealth manager who navigates financial markets on your behalf, we navigate the gemstone market — applying expertise you'd need years to develop and relationships that take decades to build. You pay for our knowledge, our network, and the assurance that every acquisition has been properly vetted.
Why Invest in Gemstones
As natural resources with finite supply and growing global demand, rare gemstones have demonstrated consistent long-term value appreciation while providing wealth preservation independent of market volatility.
Investment-grade gemstones offer a unique combination of tangible value, portfolio diversification, and appreciation potential that few asset classes can match.
-
Unlike stocks, bonds, or digital currencies, investment-grade gemstones are physical assets you can hold. They offer true portfolio diversification — uncorrelated to traditional markets and immune to digital threats or currency devaluation.
-
The world's premier gemstone mines are depleting. Burma ruby production has declined 90% since peak years, while global wealth — particularly in emerging markets — continues to rise. This supply-demand dynamic creates powerful appreciation potential.
-
Top-quality rubies have appreciated an average of 15% annually over the past two decades, outpacing most traditional investments. Exceptional stones from closed mines command premium prices at auction, with record-breaking sales year after year.
-
Gemstones represent concentrated value in minimal physical space. A single investment-grade stone can hold significant wealth while remaining portable, private, and transferable across generations without the constraints of real estate or other physical assets.

Emeralds
Prized for their vivid green hue and storied provenance, fine Colombian emeralds represent some of the rarest gemstones on earth. With major mines nearing depletion, exceptional emeralds command premium valuations and consistent appreciation.
Rubies
Known as the "king of colored gemstones," Burmese pigeon blood rubies are among the most sought-after gems in the world. With limited supply and growing global demand, investment-grade rubies have demonstrated remarkable long-term performance.
Sapphires
From the legendary Kashmir blue to vivid Ceylon stones, fine sapphires combine exceptional durability with captivating beauty. Their consistent appreciation and broad collector appeal make them a cornerstone of gemstone portfolios.
Rare Stones
Alexandrite, Paraiba tourmaline, and other exceptional rarities offer unique investment opportunities for discerning collectors. These stones combine extreme scarcity with distinctive characteristics that drive extraordinary valuations.
Our Clientele
We serve sophisticated investors who recognize that exceptional gemstones require exceptional expertise. They value transparency over sales pressure, documentation over promises, and relationships over transactions.
We work primarily with ultra-high-net-worth individuals seeking tangible alternative assets, family offices building generational wealth portfolios, and wealth managers who've been asked by clients to explore investment-grade gemstones. What unites our clients is an appreciation for quality, an understanding of alternative asset dynamics, and the recognition that access to the finest gemstones requires specialists with direct sourcing relationships in global trading centers.
Our clients understand why gemstones merit consideration as alternative assets but recognize they need experts to navigate the market effectively.
