I recently bought a ring fairly similar to this one, but in plain silver and marquasite, and costing just £15 from Accessorize. I love it so much, though, that I'd certainly consider this much brighter, funkier version by Arrieta Vogels for Shop Intuition.
The flowers are enamelled and studded with Swarovski crystals, hence it costs a bit more than my ring - $140.
