Would it be safe to wear my rolex/diamond ruby ring/yellow Gold crucifix to school?

As I've never been to a public school, but I'm going next year. so as my question says, would it be ok to wear my yacht master/red ruby diamond pinkie ring/gold crucifix/yellow gold bracelet to my new public school? It's not a ghetto school, its small. Maybe seven hundred. I've heard of iPod getting stolen there because kids leave them in their backpacks or lockers, but not pick pocketed or anything.

Why don't people like yellow gold rings anymore?

When I got married, I really wanted a yellow gold ring. I also wanted a ruby center with little diamonds on the side instead of a diamond center. It was really hard to find that combination in yellow gold. Even the diamond engagement rings were all in white gold.

I have an olive tone to my skin and white gold looks horrible on me. All the jewelers I spoke with tried to convince me to go with white gold. I finally found exactly what I was looking for, but it took a while. I'm just wondering, why is it so hard to find yellow gold anymore? I know, in my mother's day, it was very popular.

Is it ok to wear gold and silver rings together?

I prefer silver or white gold jewelry. However, I have a yellow gold and ruby ring that was my grandmother's that I wear in remembrance of her. It's just a little piece of her that I like to keep close. I feel like if I wear any other rings on that hand, they should be gold, but I don't really like gold. What are my options? My wedding set is silver and I wear on my left hand (obviously lol) and I wear my grandmother's ring on my middle finger on my right hand. Everything else (necklaces, bracelets, etc.) is silver or white gold... is it ok? Or does it look tacky?

How much would it cost to get a ruby ring reset?

I have a ring with a 3x5mm ruby set in 14k yellow gold. I don't like the style of the band, and I don't wear yellow gold. I'm thinking about getting it reset into a white gold band, and maybe adding two tiny diamonds from a pair of earrings that I don't wear very often. I think it would make a much nicer ring, but what would the price range for this be?

What do you think of yellow gold jewelry?

I've recently started wearing a yellow gold army ring...it doesn't have the antique finish, it is just gold with the ruby. My Grandpa gave it to me when I was a junior in high school, and I wore it for a few years then put it up. I recently graduated college, and instead of a class ring I decided to wear it to honor my Grandpa who died before I was able to graduate college. He got it in 1939 after he enlisted in the military. My thing is, it is a little flashy, and most people don't wear yellow gold jewelry. I like it, but it stands out. Do you think people will look at me funny because I wear it?

This is what it looks like, except it has a ruby stone and does not have any black around the letters, it is only gold.
