I remember there was quite a vivid discussion on engagement rings at one point here, so I thought we maybe needed a jewellery thread. For my part, I have a question on ring cleaning. I recently got an ring from my mom, it used to belong to her aunt. It is a solitaire ring, but not a diamond one. It has a large clear stone in a teardrop like shape, my mom believes it is quartz or similar. (My grand aunt would probably not have been able to afford a diamond of that size!). It is very dull, however, and I think even not being a diamond it should sparkle a little more. Does anyone have suggestions as to how to clean it? It sits in a prong type setting and it looks like the back side is quite dirty. For those of you who a curious, the ring looks modern, with a gold band that rises up with a gap in, and in the gap a white gold setting has the stone. A little like this, but the band is even wider at the top, and warm gold. (and the stone is semi-precious) http://www.robbinsbrothers.com/Engagement-Rings/Classic-Solitaires/Robbins-Brothers-i13615.ring so, anyone know a good way to clean it? or does anyone have any other jewellery discussion topics?
