Rough edges, blemishes, and flaws--raw gemstones create character in the jewelry they reside.  Whether it is a diamond that has been uncut, unpolished and "in the rough" or a prehistoric shark tooth, jewelry that features a raw material is beautiful and has become popular by up-and-coming designers.  You can find examples in jewelry boutiques, online or even create your own if you find a rough stone and feel it is worthy to be showcased.  I've found some great pieces that feature a Moroccan Azurite, a prehistoric shark tooth and a Kyanite crystal.  Check them out below!

This necklace is designed by Melissa Joy Manning and features a royal blue Moroccan Azurite. The style of the 14k yellow gold prongs makes it resemble bird's claws, grasping the stone. The price is $940 and it was even featured in Lucky magazine.

Designer Pade Vavra creates a tough, don't-mess-with-me look with this great white shark tooth necklace. Those are diamonds you are seeing at the top of the tooth, as well as three black diamonds at the end of the chain (not visible). All is set in 18k peach gold and can be purchased at Ylang|23, for $2090.

I love this Kyanite crystal necklace set in 14k yellow gold from Zoe Chicco. It is geniusly designed to extend from 24-26 inches in length, giving you a nice and elongated look. This will easily layer with shorter charm necklaces. This necklace is $693 and each will vary slightly.
