Gem Trio London Blue Topaz Ring Set
- Regular price
- $379.00
The Gem Trio London Blue Topaz Ring Set includes three coordinating rings designed to be worn individually or stacked together. A rich London blue topaz takes center stage, framed by lighter sky blue topaz stones and finished with sparkling white zircon accents. The shift from deep blue to icy blue creates a refined gradient with a clean, modern feel.
Wear the three rings separately for a minimal look or stack them together for more dimension. As topaz is the November birthstone, this set makes a thoughtful November birthday gift as well as a distinctive choice for anniversaries, dinners, and special occasions.
