I own two pairs of these! I grow them too.
I liked these earrings so much and the price point was so reasonable that I bought a second pair on sale. I know that there is a real leaf encased in the plating, so if the first pair wears out I will have another one ready. I know exactly what leaf this artist chose to preserve: Dischidia ruscifolia, a vining relative of the Hoya family which is very popular among plant collectors. I do grow this plant along with many Hoyas. A hanging basket overflowing with this Dischidia's vines appears as thousands of tiny green hearts, and gives rise to the common name of the "thousand hearts vine." I own several pieces of jewelry from this artist and these earrings are of the same high quality construction as his other work.
