Earring help. Is there such thing as rose sterling?

I am really lighting up the board today, LOL
A real long shot here to try and show what I'm talking about, because I can't get it to show up in pictures
Just finished cleaning these earrings that are marked sterling. They were very heavily tarnished, and now that they are cleaner, I am seeing a rose colored tint only to the leaves on the front of them. Any thoughts, pretty please?!

 

No, any alloy of silver that I know of still looks like silver.

Could be silver gilt.

 

I know Coro used to do that on some of their pins/brooches.

 

with the nice bezel set stones I would have them checked, could be gold....

 

But probably not, since they are marked Sterling.

 

Thanks so much Messi, Davey, Sharona and Af
I tried to gold test, but it's really hard because the leaf areas are not sticking up enough to get a good sample on the stone. But, from what I was able to do, those areas were testing for 14k. That could be plating though. Rose colored gold plating would make sense, and I didnt think about that. But maybe it is gold, and marked underneath somewhere I can't see it? Would, or could it be marked in 2 different areas?
Sharona thanks for the term bezel set....I didn't know that. I learn so much from you wonderful people.

 

The bases and the stone settings are probably the sterling, and the leaves gold, rose gold. I have seen combination gold and sterling vintage to Victorian jewelry. Is the word "sterling" stamped only on the bases?

Thank you Susan, much appreciated. It's stamped on the back of the screw for the clip on.

 

Victorian revival maybe. That's a 50s design overall. The stones are likely glass; the often were in 50s sterling.

 

Thank you evelyb Much appreciated

 

The word for silver covered with gold is vermeil (pronounced ver-may). I don't know whether this qualifies but didn't see that mentioned so thought that I would.

Thank you fig Much appreciated. I've read the word before, but never knew it was pronounced that way
