This black agate is a very unusual shape; for some reason it reminds me of a bird's head (although the beak is a bit short). Black lines rim the outer edges of both the agate & the druzy centre. In between, the stone is a semi-transparent grey that almost glows when you hold it up to the light - the first photo is the best example of this effect. There are also some small crystals in the white area of the "beak".
This slice of geode agate is 2 2/3 inches long by 2 1/3 inches wide (6.8 x 6.3 cm). With the sterling silver wrapped bail, the pendant part of this necklace runs over 3 inches (8 cm). The mid weight curb chain is also sterling, 22 inches (55 cm) long, ending in a standard lobster clasp. If you want a different length of chain, please contact me for a price estimate - I love doing custom orders!
