Extremely rare “double diamond” discovered in Ellendale
The discovery of an extremely rare “double diamond” in the Kimberley region of Western Australia is expected to revive the diamond mining industry by meeting the high demand for colored diamonds.
The 0.85-carat diamond that contained a smaller stone in a cavity inside was unearthed about 200 kilometers below the surface of the Ellendale alluvial deposit mined by Australia-based India Bore Diamond Holdings (IBDH).
“At first we thought it was a stone or something inside the diamond, but it was clear,” said Peter McNally, CEO of IBDH. ABC News.
“So we thought it was a diamond trapped inside a diamond. It was very exciting,” McNally said, adding that the find became more exciting as each of the stones – in its unique yellow-orange color. Ellendale Colored Diamond – produced a rare purple tint when subjected to ultraviolet light.
Similar to the famous Hope Diamond, the double diamond exhibits phosphorescence – a rare phenomenon that occurs in less than 0.01% of natural diamonds.
The find is expected to increase diamond production at the Ellendale mine where IBDH also unearthed yellow diamonds last year with rare purple fluorescence in its coverage areas.
IBDH is one of the few mining companies operating in the region to increase the production of colored diamonds to meet the growing demand for stones around the world amid the supply shortage following the closure of the mine Argyle last year, which was the largest source of colored diamonds. especially pink diamonds.
Earlier this year, IBDH obtained its 21-year mining lease for the L-Channel deposit covering approximately 2,300 hectares.
“The granting of a mining lease for our L-Channel deposit is a very important step for IBDH and is part of a targeted and innovative exploration program,” said McNally.
“We identified a large buried alluvial channel draining north to south through the Ellendale diamond field and containing thick beds of diamond gravel. Our sampling and testing program has confirmed diamond grades of up to 12.7 cpct with a high percentage of colored diamonds, including the famous Ellendale Fancy Yellow diamonds, ”added McNally.
