The Nat­u­ral His­tory Mu­seum of Los An­ge­les County (NHMLA) is hold­ing a spe­cial ex­hi­bi­tion ti­tled Green Di­a­monds: Nat­u­ral Ra­di­ance, which will add eight cases of bright colour and shine in­side the Mu­seum’s renowned Gem and Min­eral Hall.

The vi­brant di­a­monds on dis­play as loose gems and mounted jew­ellery are part of the Gamma Col­lec­tion, which was amassed over the course of 20 years and con­sists of more than 60 of the most rare and pres­ti­gious nat­u­ral coloured di­a­monds in the world.

At the cen­tre of Nat­u­ral Ra­di­ance at NHMLA is The Man­tis, the largest vivid yel­low­ish green di­a­mond ever graded by the Ge­mo­log­i­cal In­sti­tute of Amer­ica, along­side The Shangri-La, the finest ex­am­ple of a large vivid green di­a­mond, both of which are mounted in rings.

Or­gan­ised by NHMLA as­so­ciate cu­ra­tor of min­eral sci­ences Dr. Aaron Ce­les­tian in part­ner­ship with Op­ti­mum Di­a­monds, Nat­u­ral Ra­di­ance is on view from De­cem­ber 9th 2017, through April 1st 2018.

“We are thrilled to share some of the world’s rarest di­a­monds with mu­seum vis­i­tors, pro­vid­ing

op­por­tu­ni­ties to learn about the science be­hind their colour and for­ma­tion,” said Ce­les­tian. “This ex­tra­or­di­nary ar­ray of coloured di­a­monds, on loan from Op­ti­mum Di­a­monds (one of the world’s elite houses for rare and ex­otic nat­u­ral colour di­a­monds), show­cases some of the finest nat­u­rally oc­cur­ring min­er­als in the world.”

The ex­hi­bi­tion fea­tures over 60 green di­a­monds, both loose and mounted in ring and ear­ring set­tings, that show­case a va­ri­ety of shapes, cuts, and vast shades of the colour spec­trum from vivid-green and red to yel­low-green and deep grey vi­o­let, and ev­ery­thing in be­tween.

Through high­lights such as The Light of Eras­mus, an ex­tremely rare 1.63-carat vivid green­ish blue di­a­mond, the ex­hi­bi­tion gives vis­i­tors the chance to dis­cover the for­ma­tion of di­a­monds and sci­en­tific ori­gins of the green colour, in­clud­ing the gamma ra­di­a­tion, which in­spired the name of the col­lec­tion.

The ex­hi­bi­tion also ex­plores the un­solved mys­ter­ies be­hind rare ‘Chameleon Di­a­monds,’ which change colour when ex­posed to light or heat. Nat­u­ral Ra­di­ance fea­tures three of these ex­tremely rare and valu­able di­a­monds, in­clud­ing a 3.08-carat dark grey green­ish yel­low di­a­mond.

The world-renowned, 6,000-sq-ft NHMLA Gem and Min­eral Hall opened in 1978 and is one of the finest per­ma­nent ex­hibit halls of min­er­als, rocks, gems, ores, and me­te­orites in the world. The Hall houses a se­lec­tion of the Mu­seum’s ex­ten­sive col­lec­tion — dis­play­ing more than 2,000 spec­tac­u­lar spec­i­mens within two large gal­leries — which as a whole in­cludes more than 150,000 spec­i­mens and is the largest in the western United States. The Hall also fea­tures the new, trans­par­ent Min­eral Science Lab, where the pub­lic can watch depart­ment staff work in a mod­ern lab­o­ra­tory with cut­ting-edge in­stru­men­ta­tion for min­eral and geo­chem­i­cal sci­ences.
