This 18K yellow gold MARIA TASH Triangle diamond earring is a single stud suitable for pierced ears. Measuring 4 mm and featuring a threaded ear backing, this piece spotlights a 0.11 carat diamond. Without cups or prongs, it appears to float weightlessly. Galileo Galilei shared our interest in triangles, however ours is more of the MARIA TASH kind than the mathematical type.
