The Valuation and Investment Merits of Diamonds is the first book that deals with the economics of diamonds, specifically with the determinants of diamond prices. The period of 1978-1983 was chosen in order to shed light on the dramatic drop in diamond prices. Khoury clearly identifies these determinants, distinguishing them from one another by the level of impact they have on diamond prices. This book includes: a quick review of the characteristics of cut and uncut diamonds, the financial performance of DeBeers in a declining market, the economic structure of the diamond industry, the method for exercising economic control over the diamond market, the economic variables influencing diamond prices, and the modeling of diamond prices and the testing of the model utilizing advanced statistical methods.

large uncut diamond sold by Petra

LONDON (Reuters) – Petra Diamonds sold a 507-carat uncut diamond for $35.3 million on Friday, breaking a record as the highest price ever paid for an uncut diamond.

Analysts had estimated the value of the stone, one of the 20 biggest high-quality uncut diamonds, at around $25 million.

"It is fitting that the Cullinan Heritage should achieve a sale price of $35.3 million, the highest sale price on record ever achieved for a uncut diamond, as it has the potential to produce one of the world's most important polished gems," Chief Executive Johan Dippenaar said.
London-listed Petra said in a statement the gem was purchased in a tender by Chow Tai Fook Jewelry Co Ltd in Hong Kong.
Proceeds will help boost Petra's profit for its fiscal year to end-June after the firm swung to a first-half profit on higher production and sales.

AIM-listed Petra found the gem last September at its 74 percent owned Cullinan mine in South Africa, which it bought from sector giant De Beers in 2007.

The Cullinan mine has been the source of many large diamonds, including the world's largest uncut diamond -- the Cullinan -- at 3,106 carats. That gem was cut into the Star of Africa stones that are now set in Britain's Crown Jewels.

Petra was a member of a consortium that paid $148 million when buying the Cullinan mine from De Beers, which is 45 percent owned by mining group Anglo American.
