A New Gem That’s More Pure Than the Hope Diamond
- Okavango Blue graded higher than Hope Diamond for purity
- Company to undertake worldwide campaign to gauge demand
Botswana’s state-owned diamond marketer has unveiled a gem that exceeds the clarity and purity of one of the world’s most famous, the Hope Diamond.
At just over 20 carats, the oval-shaped blue diamond, known as Okavango Blue, is smaller than Hope Diamond, but graded above it in terms of purity by the Carlsbad, California-based Gemological Institute of America, Okavango Diamond Co. Managing Director Marcus ter Haar said in an interview Wednesday in the capital, Gaborone.
