These colourful earrings by Pippa Small come complete with a description of the artisan who cut the shells that feature as the main element (scroll down on the product page link above).
Small’s site explains, “Hand cut triple drop earrings crafted by our talented artisan. Shells are one of our most ancient decorations. There are strict regulations and ethical guidelines when it comes to the harvesting of shells, due to water pollution and other social and economic impacts. While found in many locations, their colours include green, pinks, purples and blues. Some even have gold or crimson toning.”
These are priced at USD$2,260.
