Postinikova-Losyeva indicates a Master using "KK" as his hallmark for this period as "Kuzma Ivanovich Konov", St. Petersburg silversmith, 1891-1917. see P-L #2599.

The years 1891-1917 would be the proper time period for this style of brooch. There should however be some quality or assayer's hallmark (ever so small) accompanying the maker's mark on the goldwork. What are the stones? They appear to be faceted?

Thank you to FA and David for the information!

FA; your has wrote "see P-L #2599", was this a pagenumber to a book of St. Petersburg silversmith?

David,
Materials was of gold, sapphire and ­diamond.

If I want to sell the brooch, are that best to going to Christie´s or Sotheby? Do some know about value of the brooch?

Peter

The most comprehensive book on Russian Imperial Gold and Silver smiths is by Postinikova-Losyeva, called "Zolotoye Y Cerebryanoye Delo XV - XX BB"
Each master listed has a specific number. In this case, 2599 the reference number in this book to that master.

David is quite right. There MUST be another hallmark at least. First, how do you know this was a Petersburg piece? Is the St. Petersburg hallmark on the brooch (crossed anchors), also there should be a gold standard hallmark on it if it is gold (most likely the number 56, probably with a kokoshnik, and either 2 cyrillic letters or a greek letter (alpha would denote Petersburg).  

Please describe specifically all other hallmarks.  For value, you should contact Sotheby's or Christies in New York. They will want all this same information.

There was a stamp of Assayer Jakov Ljapunov with a number of 56 (14kt gold) and at my research, he was worker in St. Peterburg.

Kuzma Ivanovich Konov, was he owned jeweller or worker he for some jeweller in St. Petersburg?

The St. Petersburg assaymaster using initials Ya. L in the "left facing" kokoshnik in the 1899-1908 era was indeed Yakov Lyapunov (P.L. listed number 3881).

Please forgive me, I made an error. I turned to the wrong section of the book. Konov was a MOSCOW maker, not Petersburg, and according to P-L Konov worked for himself, and had a space selling his work in GUM.

P-L lists no maker in Petersburg using the mark "KK", so perhaps you could take a closer look and see if that is the correct mark.

I see! This is a Ja.L., so that must be for assay master Jakov Ljapunov?

According to P-L Konov worked for himself, and had a space selling his work in GUM.

What or where is "GUM."? ??? :-/

so perhaps you could take a closer look and see if that is the correct mark.

This is hard to read and illegible stamp..but I think this is a K.K.? I'm sure at the firste is a K!

GUM was a large department store in Moscow.

here is a drawing of the mark from the book. I assume  your mark looks just like it, but with 56 instead of the silver standard 84.



You will see that this master worked from 1899-1903, thus narrowing the date for your piece even further.

According to the book the "possible" makers using a hallmark starting with "K" during the limited time of your piece's assay stamp (using English equivalents of the cyrillic mark):
KA: Karl Albrecht
KP: K. Parkinen
KR: unknown maker
KF: Karl Faberge

English letter hallmarks for Petersburg also possible:
KS Karl Selenius
KT Karl-Gustav Tomson

The book was published in 1995, in Moscow. Edition "unves" "trio". It is only in Russian, I have not seen an English version
ISBN: 5-88682-002-7

Have you had the sapphires in the brooch examined by a gemeologist. It could simply be the photograph that you posted but they look rather cobalt in colour which could be an indication that the stones were once pale or colourless sapphires that have been covered in a paste of iron and titanium and then heat treated to 1770° Centigrade. Could the stones be Blue Spinel (Mg Al2 O4) rather than Sapphires (Al2 O3)?
