Not everything beneath the surface is meant to be seen, only felt. Midnight Current moves quietly with hints of ocean bioluminescence.

Colour shifts along the long axis. Collector’s Guide Rarity: Midnight Current represents a rare class of Lightning Ridge nobbies defined by depth, mood, and quiet luminosity. Its electric‑blue fire suspended within a dark N4–N6 body tone evokes the glow of ocean bioluminescence — a visual effect highly prized among collectors who favour atmospheric stones. High‑dome nobbies with this level of internal depth and rolling ribbon patterning are increasingly scarce, making this piece a standout in its category. Investment Notes Blue‑dominant nobbies with aqua/teal transitions maintain strong long‑term collector demand The high dome amplifies optical depth, increasing both rarity and visual value Brightness offers a refined, immersive glow rather than intense flash Rolling flash/ribbon patterns are sought after for their fluid, organic movement The 12.30 ct weight and elongated form make it suitable for both statement jewellery and collection‑grade display Collector’s Insight: This opal rewards slow, intentional viewing. Its colour doesn’t erupt — it flows, drifting along the long axis in quiet pulses of blue and teal. The strongest fire sits in the central zone, creating a natural focal point, while the surrounding transitions evoke the feeling of light moving through deep water. Midnight Current is a stone chosen for its emotional resonance — a piece that feels alive beneath the surface. A Certified Asset Valuer has independently assessed this Opal.
