Sterling silver dogwood? ring - can't ID maker

[mimiwells]

Found this ring in a job lot.  It has  a stamp of a crown and nothing else - metal tests as sterling silver.   Any thoughts would be appreciated.  I was not able to find the hallmark although I have combed my books religiously and on line.  I even did a google pic search to no avail.  Any help is appreciated.

Sorry, I can't help you with the maker.

But, I can tell you that these aren't dogwood. Dogwood flowers have 4 petals, not 6.

I believe the flower is a forget-me-not flower.  Can't help with the id of the maker's mark.
