This dainty and stackable ring features a solitaire genuine ruby which is traditionally known as July's birthstone. The band has been handcrafted using silver plated copper or 14k gold plated copper, both with a clear e-coating to provide tarnish resistance for up to 4 plus years. Removing before washing hands, showering, swimming, etc is not required but recommended to increase the ring's lifespan even further. The metal options are considered hypoallergenic and will not turn the skin green as long as they have yet to tarnish. Available in sizes 5 through 10 with the most popular sizes being 7 and 8.
