About This Collection

Opals are nature's most unpredictable gems. The play of color inside each stone is completely unique, shifting from fiery reds to ocean blues depending on the angle. As the October birthstone, opal demands a bit more care than harder stones, but that's part of what makes it special. I select opals for their color play and fire, then design settings that protect while letting all that color shine through.

Frequently Asked Questions

How should I care for opal jewelry?
Opals contain water and need moisture protection. Avoid extreme heat, dry environments, and prolonged direct sunlight. Never use ultrasonic cleaners. Store in a soft pouch and occasionally wipe with a slightly damp cloth to maintain hydration.
What birthstone month is opal?
Opal is the birthstone for October (alongside tourmaline). It's also the gem for the 14th wedding anniversary.
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.
