This first one is a necklace, obviously. The middle bit is 11 inches of sterling silver viking knit, capped off with sterling bead cones and 6mm malachite rounds. The pendant is a hand-carved malachite pendant, carved by Matheson Gem Works on Etsy. The bail is handmade from sterling silver wire with spirals for interest. The necklace is finished off with more malachite beads and a simple sterling silver chain and a large lobster clasp. It has a 1" extender with a malachite dangle. This will be priced at about $120, I haven't done all the math on the price yet, so that's a rough figure.
These next earrings are made with larimar and sterling silver. Larimar is a rare stone found only in the Dominican Republic that ranges in color from white, to light blue, green-blue, and dark blue. While the pectolite it is formed of is fairly common, the light blue coloration caused by the substitution of cobalt for calcium in the mineral makeup of the stone. These are on hand-wrapped sterling silver headpins and sterling silver French earwires. They will be priced at about $25-$28. Due to the rarity and price of larimar, any earrings made of the real thing will be more expensive.
These have not yet been listed on Etsy since I have yet to get good pictures of either piece.
