Teal Iridescence : Art Deco Morpho Butterfly Wing Brooch Circa 1920

Sold The intensity and iridescence of this phenomenal piece is absolutely astonishing. The colour is electric from edge to edge an intense peacock teal that transitions to electric cobalt blue, shimmering in the light from this perfect preserved butterfly wing. An exceptionally fine example of butterfly wing jewellery. Yes, a real honest-to-goodness butterfly wing is responsible for the glorious colour inside this eye-catching statement brooch, in this case from the Morpho butterfly from South and Central America. The Morpho butterflies are among the largest in the world, with a wingspan of 7.5 to 20 cm. The iridescence in their wings is caused by the structure of the wings which create colour through diffraction and interference. It’s a fascinating phenomenon (if you’re interested this page has a good explanation). I can’t help feel that it’s pretty neat that this snippet of butterfly, whose entire life from egg to caterpillar to butterfly is only 115 days should have managed to survive, preserved in silver and crystal, for 100 years. That’s a pretty good legacy! Manufacture:  The brooch is modelled in sterling silver throughout, a rubbed ‘Silver’ mark can be found on the reverse. A perfect oval of iridescent colour changing butterfly wing has been preserved beneath a dome of glass. Fastens with a tube hinge and c-clasp. The brooch measures 26.2mm x 19.45mm. Weighs 5.46 grams. Condition:  Very good antique condition. Ready for immediate wear.
