Roberto Coin help

[MoonPhase]

Hello,
My friend received a Roberto Coin Pois Moi Oval Bangle which is also known as the Symphony Dotted Hinged Bracelet. I was curious about the marking on the bracelet. I noticed on the side where the ruby is located, the left side of the bracelet, it's marked RC and on the other side, the right side, it's marked 18KT and below the 18KT it's marked RC TH. My friend says she bought it on the preowned market and supposedly it was authenticated. I don't own any Roberto Coin jewelry, but I searched online and supposedly RC is made in Italy. I don't know if RC has always been made in Italy or was there a time when it was made elsewhere. We searched TH in gold markings and we couldn't find much info, except that it could mean Thailand. We thought about calling a boutique, but we believe they will not help since it was not purchased from them. Any info is greatly appreciated, thanks!

Call, they won't know how it was purchased, tell them it was a gift

I checked my chain necklace and bracelet and both are marked with the signature ruby, Italy, 18k and what appears to be a serial number and a star, the print is so tiny it's kinda hard to make out. I purchased both at a jewelry store that is an authorized RC seller ~ when I purchased the necklace it had to be ordered directly from RC because the store didn't have it in stock.
Other pieces could be marked differently though ~ maybe each line has it's own markings, mine are both chains, not bangle types. Hope this helps

Thank you Swanky for your reply...So, we did as you recommended and called a boutique, but unfortunately they did not know what the TH could mean. We decided to go to Bloomingdale's, because they carry Roberto Coin. Luckily they had the same exact bracelet, we looked at it, and theirs had the same markings. We asked the SA if she knew what the TH stands for and she said she did not and said maybe it was the manufacturer's stamp. So, although we don't know for sure what the TH means, we do feel much better knowing the bracelet at Bloomingdale's also had the same markings. Thanks!

Thank you for your reply JOJA...After looking at a lot of their jewelry, I did notice the markings vary, just as you pointed out. Thank you!
