This ring by Native Gem looks expensive but is light on the wallet.

Made of vermeil (gold plated sterling silver) it’s set with aquamarine coloured cubic zirconia. They note, “The pieces are designed to be worn, and cherished. By using only hypo-allergenic, lead and cadmium-free metals: 14K gold fill, vermeil and sterling silver, we are filling the gap between cheap throw away lead-based jewelry and ultra-expensive fine jewelry.”

This is priced at USD$136.
