The versatility of stacking rings is that you can mix and match these rings in so many different ways. The more rings you have, the more choices you have. Wear them all together, 2, 3, or 4 at a time. I love the way you can alternate the patterns. So for example, if you choose to wear 3 gemstone stacking rings, you can have 3 different looks by alternating the pattern of the rings--kind of like a puzzle ring. With the 3 stone ring above, wear the opal in the front and the darker coral in the back and switch, you could put the large light coral in the back, or the front and switch the other smaller rings around it.
Monday is one look, Tuesday another. You can also wear them individually--one on every finger if you choose, or 1 on each hand.
Another unique way to wear them is with small thin bands in-between.
Since gemstones have different meanings, i.e. ruby - love, citrine - happiness, peridot - good cheer, many people give these rings as friendship rings too because of their sentimental value.
They definitely will enhance the colors of your wardrobe.
Best thing about these rings is their value factor--one price for all these rings :)
