As a clear distinctive logo it looks good but given it's not a widely recognised symbol, which in todays proliferation of 'euro' symbols could mean anything, I feel it needs support from text.
If there is no way of incorporating the name in the logo it needs the support with the word Sammio nearby and in my opinion in a clear modern font, rather than a script. That would reflect the modern adaptation of am old basis, perhaps? not sure I am expressing it well but it's a mixture of old and new but not overtly.
