10k Solid Gold Citrine Vintage Ring

This is a beautiful vintage 10K yellow gold and lemon citrine gemstone ring. I'll start by saying the ring belonged to my late aunt and she received it from her in-laws. She left me the ring in 1999 and I've had it packed away in my storage facility since 2000. I'm not exactly sure how old the ring is, but just looking at it, you can tell it's a vintage style. Now, with saying that, the ring is in excellent condition, especially for its approximate age. There was a small little dent in the back part of the band that is not visible when wearing the ring. The 3 citrine stones are in excellent condition. It's marked 10K, and it is a size 7. I've had a jeweler test the gold and gemstones. The Jeweler suggested that the ring is pre-1970s but couldn't give an exact date. Feel free to ask questions. Thanks
