Logan Hollowell - Turquoise Summer Triangle Constellation Earrings14K gold and turquoise studs. These earrings are the same size as our Summer Triangle Constellation Earrings. The Summer Triangle is a Northern Hemisphere asterism (stars of similar brightness recognized in a distinctive shape). Unlike many other asterisms, the Summer Triangle is actually an amalgamation of stars from three separate constellations. We in the Northern Hemisphere can see the Summer Triangle for part of the night at any time of the year.
