Vintage Pin 970 Fine Silver Butterfly or Dragonfly Inlay Moveable Wings trembler

Description

Up for auction is an insect pin, handmade of fine silver hallmarked: 970 with moveable inlaid wings in lapis, malachite and a tan quartz. It measures roughly 2" wide across the wing span by 1 5/8" along the segmented abdomen and weighs 5.47g on a digital scale prior to packing. It was sourced second hand from a vintage wares market in the East Bay, beyond this I have no specific history on it.
Please review images for your take on age, design and condition. Handmade hinged-wing trembler pin...dragonfly form, can't say I've come across one before. It has no mark indiciating country of origin but I'd guess it to be of Mexican crafting and probably 60 years old or better, somewhere around 1960-ish. Please note (and best seen in final image) a fracture in the webbed portion of the upper most wing (closest to thorax represented by a shot of silver)...a hairline across the webbed area of stone (it remains securely in the channel and the while not readily seen it is there and important to mention).  Sweet pin are offered in a No Reserve auction format with low opening bid; and 'Best Offers' are considered prior to any bidding activity in the auction. Any interest in adding to your wearable collection of winged creatures?
