Can be as low as $300 to $400 each. Go SK jewellery. Quite
cheap.
don't need anything fanciful one, cuz this is for wearing a long
time. Something easy to maintain. Dun need diamond, cuz usually the
diamonds are very small. No point.
The big diamonds one are for proposals only. You dun need to wear
that every day (unless you want to show off).
Now ppl still wear silver or platinum. Some go for half yellow
gold/half silver. Seldom ppl go for all gold, cuz it's
outdated.
Dun need to be too expensive. No point. Expensive or cheap, it
still serve the purpose. Just select something you like, easy to
maintain.
