by: Anonymous

From 1904 until 1998, the following symbols were used in addition to the appropriate British Hallmark to indicate that an item was of foreign manufacture.

The last poster was correct in that they are Birmingham hallmarks. The 375 is the gold content also known as 9 carat (9ct) gold.

* 24 carat (millesimal fineness 999)"PURE GOLD"
* 22 carat (millesimal fineness 916)
* 20 carat (millesimal fineness 833)
* 18 carat (millesimal fineness 750)
* 15 carat (millesimal fineness 625)
* 14 carat (millesimal fineness 585)
* 10 carat (millesimal fineness 417)
* 9 carat (millesimal fineness 375)
* 8 carat (millesimal fineness 333)

Often English, European, and other Countries will hallmark with the "fineness" such as 750 for 18k or 417 for 10k

starstarstarstarstar 		Birmingham Gold Bracelet
by: Yvonne

Hi Stephen - Yes. I agree, you do have a very nice gold bracelet.

OK. From my research, the country purity marks, will be the triangle mark, followed by numeric standard mark, which in this case is - 375:

UK - BIRMINGHAM on all ct grades except 24ct GOLD on LOCAL & IMPORTED WARES - ca 1998
WITH the numeric standard mark, date letter and sponsor's mark.


The date letter looks like the Birmingham date letter for 1969.
The link is unusual as you say , not manufactured, it looks similar to sponsor's mark:

ARTHUR CREIGHTON (mostly Jewelry & Silverwork, Morecambe College of Arts & Crafts, UK) - ca 1950s - 1960s
