Impregnated Opal

Impregnated Opal is a lab-created opal formed from microscopic silica spheres arranged into the precise, repeating lattice that gives opal its signature play-of-color, then stabilized with 15% resin. As light diffracts through this ordered structure, the material flashes with shifting spectral colors that shimmer and change as the stone is turned. The 15% resin content strikes a balanced middle ground — more stable and forgiving to cut than resin-free opal, yet harder and more heat-tolerant than high-resin varieties. Available in a range of body tones and vivid color patterns, this versatile material is a dependable, all-around choice for cabochons, inlay, and intarsia work.
