Ring markings

[lawsonland]

Need help on the ring marking. The Ring is 2 metals and 3 tiny diamonds. gold & silver? its marked 375 (which is ~9k) then has AG. I think it might be for silver but its not a normal A & G. I'm wondering if its a ring maker mark. the other marking is 0.015 W SI
Any ideas on "W SI"?

Sorry, pics are too blurry to make out marks. 375 is 9 karat gold. Au means gold (if it's Au not ag). Are you sure it's not "VVSI" instead of "WSI"? VVSI is a grade of the clarity of the diamonds most likely. VVSI is closest to flawless I think.

AG may be the maker AG & Sons out of the U.K.

Google Antique Jewellery University (I kid you not) and go to jewely makers' marks. Could it be Aisenstein & Gordon, Philadelphia PA USA, c.1934 712-14 Sansom St. Philadelphia PA?

Heh...

AG = "Almost gold" :P ... just kidding.

9k is still gold yes.... but barely :P

I think you may be right about AG & Sons. The name is it is European and it looks similar to the rings on the site.
But I can't find what their markers mark looks like.
The ring has a slanted "A" and a "G" I outline it

I thought maybe a European maker because 375 is a European mark. I too looked for their makers mark, but kept getting bottles of bourbon with red wax tops.....

I agree, that does appear to be the way he does his initials: "August Gerstner" ag mark - Google Search

I agree it may be the rating of the diamond here is a list

Flawless (no inclusions under 10x loupe)
IF (internally flawless, surface blemishes exist)
VVS 1, 2 (very, very slightly included: minute inclusions)
VS 1, 2 (very slightly included: minor inclusions)
SI 1, 2 (slightly included: noticeable inclusions)
I 1, 2, 3 (included: observable inclusions)

(copied from Diamond Grading - Understanding Carat, Clarity, Color, Cut)

the 0.015 could refer to the diamonds Carat.
