I searched online and on this forum and have not found any reference to this brand.
Do you have any better photos? It's hard to say anything about them from that photo alone.
I will add this caution-- any strand can be put into any box. At an antiques collective shop a few years back, I saw a strand of pearls in brand-name box labeled cultured pearls. I asked to see them, but as soon as I picked them up, I realized they were not only imitation, but cheap plastic ones.
