Tanzanite Twist Ring By Lauren KTanzanite Twist Ring by Lauren K. Every piece of the Lauren K Collection is proudly crafted in New York City. The Lauren K Collection is comprised entirely of handpicked gemstones, crafted in 18 karat gold, and finished with delicate micro pave. Each stone is carefully selected for a variety of reasons. In fact, very few are ever chosen for their unspoiled beauty. Instead, most stand out for their characters and flaws which give the finished piece its own distinctive personality and unique look. Our gemstones are always the “star of the show”. Nothing in the collection is mass produced, creating pieces that speak to each individual buyer. Each stone is one of a kind, the finished product may vary from the stock photo as shown.
