Product Specifications Material Astral Opal™ (Lab-Grown Synthetic Opal, 80% Silica, 20% Polymer) Color Play Primary: Baby Blue | Fire: Yellow & Green Grain Sizes Fine (0.3mm - 0.5mm), Medium (1mm - 2mm) Hardness 4 on the Mohs scale Heat Resistance Up to 250°F / 120°C Why Choose Our Crushed Astral Opal™? Aquatic Fire & Color: Meticulously grown to display a beautiful mix of light and dark blues that mimic the gentle waves of the ocean. Unmatched Stability: Guaranteed not to crack, craze, or yellow over time, offering superior durability over natural opal. Easy to Work With: Softer composition is perfect for inlay, turning, and cabbing without splintering. Coverage: One gram is enough for 3-5 standard ring inlays or to fill a 1.5" x 1.5" (4cm x 4cm) area at a depth of approx. 1mm. Creative Applications Jewelry & Ring Inlay: Ideal for creating oceanic, nautical, or water-themed custom jewelry. Custom Woodworking: Creates a tranquil "river" or water effect when used to fill voids in wood slabs. Resin Art & Casting: The perfect choice for ocean-themed resin pours, serene coasters, and art pieces that capture the sea. Pen Turning: Craft custom pen blanks that evoke the calm and beauty of a tranquil underwater kingdom. Pro-Tip: The opal's true vibrancy is revealed when "wet" or mixed with a binder (like resin or CA glue). For the most dramatic fire, use a dark base, such as black paint or dyed epoxy, to enhance the contrast against the blue flashes.
