Mystery of the Thai Jewel

I found this receipt between my dad's photos. Who was this ring intended for and where is it now? The "blue star + diamonds" might have been a sapphire ring with a long star that I once saw but I'm not certain. I have photos of my dad traveling Italy, Japan, and the US in the 70's but hadn't come across evidence of Thailand until now. 

According to the business card illustration, they also sell miniature elephants and tusks!
