Frequently Asked Questions

What is black spinel and how is it different from black onyx?
Black spinel is a natural gemstone with a brilliant shine that black onyx lacks. Spinel has more depth and fire, making it the preferred choice for fine jewelry. It rates 8 on the Mohs scale, making it very durable.
Are Ulka Rocks jewelry pieces one-of-a-kind?
Many pieces are truly one-of-a-kind due to unique stone combinations and natural gemstone variations. Other styles are produced in limited small batches. Since I use natural gemstones, each piece has unique color and character even within the same style. Once sold, most designs cannot be exactly replicated.
What materials does Ulka Rocks use?
I work primarily in sterling silver (.925) and 14k gold with natural precious and semi-precious gemstones. All pieces use genuine, untreated or disclosed-treatment gemstones. Each product page lists exact materials, gemstone details, and metal finish.
