Secrets of the Hope Diamond Revealed
Recent research projects update a storied history
Dr. Jeffery Post, Curator, Gem and Mineral Collection, Smithsonian Institution (bio)
The Hope Diamond is one of the most famous gemstones in the world. It is familiar to most people because of its fascinating human history which includes kings and thieves and perhaps a curse or two, but it is also a rare blue diamond, the largest and finest of its kind known. Despite its long history in the public eye, the diamond still prompts many questions.
Was the Hope Diamond cut from the great French Blue Diamond that was stolen during the French Revolution in 1792? Are there other blue diamonds that were cut from the same original parent stone as the Hope Diamond? Why does the Hope Diamond emit an intense ember-orange glow after exposure to ultraviolet light? This illustrated presentation will explore the history of the Hope Diamond and describe recent research projects that attempted to unlock some of the secrets of the Hope Diamond.
Dr. Jeffrey E. Post, a native of Wisconsin, received Bachelor of Science degrees in geology and chemistry from the University of Wisconsin - Platteville, and his Ph.D. in chemistry, with a specialty in geochemistry, from Arizona State University. READ MORE…
From Gemology to Mineral Physics & Back Again
Including an update on a gem of the future: Nano-Polycrystalline Diamond
Elise Skalwold, Consulting Gemological Curator, Cornell University (bio)
In the author's ever-expanding experience of the world of gems, the study of gemology has led her on an unexpected and fascinating journey into the realms of mineralogy and high-level mineral physics research. Through a behind-the-scenes tour of her own collaborative research projects, this presentation gives the audience a taste of the complex scientific efforts which directly or indirectly support the day-to-day gemological science on which the gem industry relies, but which often remain relatively invisible. Central to the story are her co-researchers and other colleagues who enrich the quest for understanding and interpreting this fascinating world.
The thread which binds this journey is the intense investigation of a blue crystal included within a diamond macle. Over a four year period, some of the most technologically advanced instrumentation in the world has yielded volumes of data and a conclusion that this pleochroic crystal is olivine, though as yet no conclusive reason for its anomalous color. Nonetheless, the high degree of scrutiny to which this diamond and its inclusions have been subjected is in itself a remarkable story and provides insights into a world deep within the Earth – arguably one of its last frontiers and one which is otherwise inaccessible.
Inextricably linked to this story is the Diamond Anvil Cell (DAC), a remarkable instrument used in high pressure research. Not only does the DAC utilize gem quality diamonds in its own construction, it is also used to study the Deep Earth environment in which diamonds form. Gemmy nano-polycrystalline diamond (NPD) plays an important role in both the DAC and in our understanding of natural gem diamonds.
