Find Nemo, Imperial looking Red Spinel, Lapidary Arts and Natural History treasures in Bonhams upcoming sale

The Imperial State Crown worn by Queen Elizabeth II is decorated with a large red spinel. The uncut red spinel is 170 carats and is often called Black Prince’s ruby. Red spinels are mostly found in the same mines as rubies, and the two are often mistaken for each other. A similar red spinel from Mahenge, Tanzania is available in this Fine Gems, Opals, Lapidary Arts, and Natural History auction from Bonhams. This oval-cut spinel weighs approximately 18 carats, and it is distinguished by a rare combination of excellent red color, good clarity, and its large yet well-balanced size. Its neon red color is attributed to a very high quantity of chromium in its chemical composition. Another notable gemstone from the African continent is amethyst. This phenomenal gemstone from Rwanda is a member of the “100 Carat Club.” It is cut in a fine triangular shape and weighs approximately 137 carats. This amethyst was discovered in Rwanda in 2015. It possesses good transparency and a high luster violet hue with hints of red. 

For opal enthusiasts, there is a black nobby opal from Australia. It weighs approximately 17 carats. This solid oval cabochon black opal is a classic example of a “nobby” or nodule opal. Nobby opals have rich saturation of full spectral colors that can be observed from any angle. Black opals, because they are so hard to find, are one of the most expensive gemstones available on the market. Elsewhere, lapidary lovers can find a sculpted, playful clownfish duo by Peter Muller. It is a large quartz cluster with crystals and two clownfish made of bright orange eosite agate from India inlaid with striping of white quartz and black agate. In an imaginative use of minerals, as if evoking a coral reef upon which the two clownfish play.
