💎 LuAG Gemstone Rough — Neon Green Lumogarnet with Intense Fluorescence
Unleash the glow with LuAG (Lutetium Aluminum Garnet) — a lab-grown garnet that radiates with intense yellow-green fluorescence and exceptional clarity. Produced using the Czochralski method, LuAG is part of the lumogarnet family, known for their vivid glow under UV and blue light. With a hardness of 8.5 and no cleavage, LuAG is ideal for faceting, collecting, or creating custom jewelry that turns heads in any light.
✨ Key Features:
- Color: Pale green to clear in daylight; neon yellow-green under UV
- Fluorescence: Extremely strong under UV and blue light — brighter than Ce:YAG
- Hardness: ~8.5 on Mohs scale — highly durable and facet-friendly
- Refractive Index: ~1.83 — excellent brilliance and depth
- Dispersion: ~0.028 — noticeable fire with vivid flashes
- Density: ~6.73 g/cm³ — heavier than most garnets
- Melting Point: ~2500 °C (4532 °F) — extremely heat-resistant
- Origin: Lab-grown via Czochralski pulling method
- Crystal System: Cubic — no cleavage, ideal for clean faceting
Whether you're a lapidary artist chasing bold fluorescence or a collector drawn to rare and radiant materials, LuAG offers a mesmerizing blend of science and sparkle. Each rough piece is sold by weight and ready to be transformed into a gem that glows with personality.

Large and flawless lumogarnet. I look forward to cutting this stone in the future, it is ideal for a large single die, and if I am careful about how I design it, I will have plenty of extra material for smaller cuts.
Accurate picture and looks fantastic.
Got the material as it is luridly fluorescent.
Looks good, anxiously waiting to Haven IT faceted
I acquired some LuAG from Tom's Box of Rocks. Fascinating material with interesting properties and excellent service from Tom.
