Ranking of Notable Diamonds Valued by Gem Experts

In the realm of precious gems, a select few diamonds have left indelible marks on gemmology, captivating the world with their remarkable characteristics, provenance, and impact. Here are the top five historically significant diamonds that have shaped gemmological history:

1. **The Koh-i-Noor** Known as the "Mountain of Light," the Koh-i-Noor is considered the world's most famous diamond. Originally weighing 793 carats, it was mined in India’s Golconda region and has been shaped over centuries into a 105.6-carat gem. Its historical significance stems from its passage through powerful empires—the Mughals, Persians, Sikhs—before coming into British possession. Its storied and somewhat controversial history makes it a symbol of imperial legacy and gemmological prestige.

2. **The Hope Diamond** This 45.52-carat blue diamond originated in the 17th century from India’s Kollur Mine. It was the first notable blue diamond discovered, with its rare color caused by boron impurities. Owned by Henry Philip Hope in the early 1800s, the Hope Diamond is closely connected to legends of curses and tragedies. Beyond folklore, its exceptional color, size, and cutting style have made it a centerpiece in gemological study and a popular exhibit at the Smithsonian Museum.

3. **The Cullinan Diamond** (implied though not detailed in search results, but historically significant) Historically the largest rough gem-quality diamond ever found (3,106 carats), the Cullinan was cut into several major gems that became part of the British Crown Jewels. Its sheer size and flawless quality revolutionized diamond cutting and royal gem collections worldwide.

4. **The Marie-Thérèse Pink Diamond** A rare fancy purple-pink diamond dating back to the 18th century, uniquely cut in the period style. It boasts a distinguished royal provenance, passing through European royalty such as Duchess Marie-Thérèse of Angoulême and Queen Marie Theresa of Bavaria. Its intense color, historical cutting technique, and well-documented lineage emphasize both artistic and gemmological importance.

5. **The Regent Diamond** (commonly recognized as historically significant though not mentioned explicitly in the results) Discovered in India in the 17th century, the Regent Diamond is famed for its exceptional brilliance and was owned by French royalty, notably King Louis XV and Napoleon Bonaparte. It influenced cutting technology and the perception of diamonds as symbols of power and luxury.

These diamonds are essential milestones in gemmology due to their unique physical properties, remarkable histories intertwined with world events and royalty, and their influence on diamond cutting, valuation, and cultural symbolism in the gemstone world.

In addition to these renowned diamonds, other historically significant gems like the Dresden Green Diamond and the Deepdene Diamond have contributed to the understanding of diamonds and gemmology. The Dresden Green Diamond's history predates diamond color treatment, making it crucial for gemmologists to study it to learn how to identify natural green diamonds. Edward Gubelin raised concerns about the Deepdene Diamond's treatment before the 1971 sale.

Furthermore, the Moussaieff Red Diamond, weighing 5.11 carats, is the largest Fancy Red diamond ever graded. The Deepdene Diamond was sold at Christie’s Geneva in 1997 for $715,320. The Dresden Green Diamond and the Deepdene Diamond are examples of historically significant diamonds that have contributed to the understanding of diamonds and gemmology.
