curious about this too
interestingly it seems their trademark is pending and they've just filed it last year.
I once ordered a 14kt singapore from sarraf.. their 14kt is so dull it looked like 10kt. worse. Ive seen lots of 10kt that was more buttery than that 14... must be their alloy 🤷♀️
anyway I returned it.
looked and felt cheap
