In Situ Growth of Ruby within Metal Jewelry Structures

This work explores the innovative in situ growth of ruby crystals within metal jewelry structures, merging artistic creativity with scientific methodology. By re-exploring historical practices where art and science coexisted, this research highlights the potential of an interdisciplinary approach. Ruby crystals were grown via Al2O3–MoO3 systems with a Cr2O3 dopant, both in isolation and into platinum structures, and the underlying crystal growth mechanism was explored, revealing a deeper understanding of the Molten INtermediate Decomposition (MIND) mechanism and MoO3 flux methods. The feasibility of integrating crystal growth into jewelry design is demonstrated, and its potential impact on the field is explored. This process is proposed as a novel approach to jewelry making that celebrates the natural beauty of crystal growth features, challenging traditional perceptions of lab-grown gemstones.
