Black & White Glass and Stone Bead Necklace with Extender and Sterling Silver Clasp. This a very versatile necklace that can be worn with many different clothing styles and in many different seasons. The Czech faceted pressed glass beads refract light beautifully. The central black agate bead is accented by two figured glass beads. The length of this necklace is 21-1/2" with a 2" extender. Clasp is a sterling silver hook and eye. A jewelry gift box and a velvet pouch are included with this necklace. Each of our designs at J&M Studios is individually created from a palette of colors and types of materials. We strive to give each design its own personality by using contrasting, coordinating, and/or complementary colors and materials. Our hope is that whoever wears our creations will enjoy and feel good about wearing them. Thanks for visiting our store. We are continually creating new types of jewelry and designs to add more variety to our offerings. Please check back often.
