Did You Know Iran’s Crown Jewels Help Back Its Currency? Here’s How It Works

The royal jewels of Iran include a remarkable 34-kg solid gold globe studded with over 51,000 gemstones, where emeralds are used to represent the oceans.

Deep inside a heavily guarded vault beneath Tehran lies one of the most extraordinary financial assets in the world — not gold bars or foreign currency reserves, but the dazzling jewels of Iran’s former royal family.

These jewels are not just historical treasures. For decades, they have played a surprising role in supporting Iran’s national currency, the rial. Here’s how this unusual system works and why it still matters today.

A Treasury Unlike Any Other

Iran’s royal jewel collection, often known as the Imperial Jewels of Persia, is widely regarded as one of the richest and most spectacular collections of gemstones ever assembled.

The treasury reflects more than 2,500 years of Iranian monarchy, with many of its most significant additions made during the Safavid, Qajar and Pahlavi dynasties.

Over centuries, Persian rulers accumulated crowns, thrones, swords, shields and ceremonial regalia studded with thousands of diamonds, emeralds, rubies and pearls. Today, the collection includes some of the most famous gemstones and royal artefacts in the world.

Some of the most remarkable pieces include:

Darya-ye Noor (Sea of Light): Considered the crown jewel of the treasury, this extraordinary gemstone is believed to be the largest known pink diamond in the world, weighing about 182 carats.

The Jewelled Globe: A striking 34-kg solid gold globe, set with more than 51,000 precious stones. Emeralds mark the oceans, while diamonds, rubies and other gems outline the continents.

The Pahlavi Crown: Created for the coronation of Reza Shah in 1926 and later worn by Mohammad Reza Pahlavi, the crown is decorated with 3,380 diamonds, 369 pearls and a 100-carat emerald at its top.

The Peacock Throne (Sun Throne): Commissioned in the early 19th century, this grand platform-style throne is covered with over 26,000 precious stones, making it one of the most elaborate royal thrones ever created.

The Samarian Spinel: Weighing around 500 carats, this deep red gemstone is regarded as the largest known spinel in the world and is among the rarest pieces in the treasury.

Today, these priceless items are kept in the Treasury of National Jewels under the supervision of Iran’s central bank.

When Jewels Became Financial Assets

In 1937, during the rule of Reza Shah Pahlavi, Iran’s parliament made a historic decision: much of the royal jewel collection would be transferred to the state and placed in the vaults of Bank Melli Iran (later the Central Bank).

The goal was not merely preservation. The jewels were designated as national financial reserves to strengthen the country’s monetary system and help back its currency.

In simple terms, the gems became part of the assets that supported the value of the Iranian rial.

What It Means To “Back" A Currency

Historically, many currencies were tied to gold reserves under the gold standard. Governments could only issue money if they held sufficient gold in reserve.

Most countries abandoned this system decades ago. Modern money is usually fiat currency, meaning its value depends largely on trust in the government and economy.

Iran’s system echoes the old idea uniquely. The royal jewels function as collateral assets on the central bank’s balance sheet, symbolically supporting the national currency and limiting unchecked money creation.

While the jewels are not traded or sold, their immense value provides a theoretical financial cushion for the state.

Why Iran Still Uses This System

Very few countries treat royal treasures as monetary reserves today. In most monarchies, crown jewels are simply historical artefacts or museum pieces. Iran’s case is different for several reasons:

Historical accumulation of wealth: Persian rulers collected vast treasures over centuries through conquests, tributes, and trade.

Political transformation: Even after the 1979 Islamic Revolution ended the monarchy, the state retained the jewels because of their economic importance.

Sanctions and financial isolation: Unlike overseas reserves that could be frozen by foreign governments, these jewels are a domestic asset fully under Iranian control.

Does This Actually Stabilise the Currency?

Not directly. Inflation, exchange rates, sanctions, and economic policies still determine the real value of the Iranian rial. The jewels themselves are rarely touched and remain locked in the central bank’s vaults.

But symbolically and institutionally, they act as a reserve of tangible wealth — a reminder that behind the currency lies a finite store of real assets.

Putting a precise price on the collection is nearly impossible because many pieces are unique and historically priceless.

However, unofficial estimates suggest the entire treasury could be worth tens of billions of dollars, making it one of the richest jewel collections in the world.
