Ring Evaluation

I am holding a diamond ring & a ring inherited from nana. Walking with me is Sofian, we walk into this ring shop and asked them to evaluate the ring. She then told us that it is 16ct, and made of such & such, she then accidentally drop the other ring. And she seemed to be surprise by that other one, that she thow a pair of dice a couple of time & spin drop the ring. The ring seems to spin faster rather than slower around a non seen axis.
The software mentioned something to me in indo. She started to speak indo too. She told us we could rent any jewelry for any occasion. Sounds interesting.
