OK, I've taken a closer look and have a few possibilities for you.
The ring is most likely close at hand or not far from where it's supposed to be. It could be in an informal room like a den, possibly in a comfortable location within the room, like the cushions of a sofa or "easy" chair. If you think you lost it outside the home, it could be in the yard, or (less likely), in the car, perhaps between the seat cushions. It wouldn't be easily visible, in any case. The idea of "low," or "bottom" comes up. so it could be near the floor, or simply downstairs somewhere in the house. Another possibility is that it's "near water" like a sink, bathtub or drain. If it's small enough to go down a sink drain, it could be at a "low point" like the drain trap. The basic testimony is that it's misplaced close to where you last remember seeing it, and concealed from view. Since it's a "shiny" item (the Sun is actually the significator in this chart, not Venus), use a flashlight to see if you get a reflection. It doesn't appear to be with or near other objects that might give away its location. With some diligence (it won't just fall into your hand), it's likely to be found.
Good luck!
