Лот 63 | DIAMONDS FROM OUTER SPACE — COMPLETE SLICE OF DHOFAR 1989
Оценочная стоимость
$ 1 500 – 2 500
Dhofar 1989 is a textbook example of an exotic ureilite. Somewhat triangular, this complete slice is wrapped in fusion crust and displays a classic cumulate texture, the result of the settling of olivine and orthopyroxene grains to the base of a magma chamber on an asteroid. The dark patches seen are flakes of graphite, a crystalline form of carbon, which are abundant in Dhofar 1989. Diamonds are another form of carbon, and are richly abundant in this specimen. For that someone special.
Christie's would like to thank Dr. Alan E. Rubin at the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles for his assistance in preparing this catalogue.
79 x 108 x 4mm (3 x 4.25 x 0.1 in.) and 64.78 grams
