A Fabergé gold-mounted Siberian amethyst and diamond shaped rectangular brooch signed with the initials of workmaster August Hollming, St Petersburg, 1908-1917 and which is approximately 2.8 centimeters wide. A very slight chip to the amethyst is visible from the back, but not from the front as the mounting obscures it.
