Antique Imperial Faberge Guard Helmet Pendant By Erik Kollin Silver & Gold

I believe this to be late 19th century 14k Gold (stamped but cant make out on picture) 875 Russian Silver (clearly stamped) and Nephrite Jade Helmet Pendant circa late 19th Century. Possibly Faberge, the Imperial Bodyguard Helmet with the silver star of the Order of St. Andrew surmounted by a Gold Imperial Eagle, issuing a nephrite egg. Not 100% sure on the value but Im lead to believe its in the thousands of pounds from my research.
