One of our favorites is the Clean Water Ring ($400):
"My vision for this collection was to create sexy versatile pieces that would feel perfect for those balmy summer nights- pieces that a woman would instinctively pack if heading to a sunny and exotic vacation spot," said designer Christine Mighion.
Ten percent from the proceeds of the Clean Water styles will be donated to CharityWater.org, which brings clean drinking water to people in developing nations.
Priced from $78 to $1050. Available at www.christinemighion.com.
Another stand out is this set of Long Shore earrings ($540) made with blue topaz and recycled 14k gold.
