The modern sterling silver chevron earrings are 1/2" long by 1/4" wide. The post is placed behind the second gem from the top, allowing the studs to drop approximately 1/4" below your piercings. Each chevron charm is set with five sapphires approx. 2.5- 1.7mm in diameter.
Alter the look by having the arrow facing in or out!

If you would like this style in another color or gem variety I am happy to forward images of gem samples to view.
