Why Choose Our Crushed 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.

Everything You Need to Know About Crushed Opal

About Our Crushed Opal

Our Crushed Opal is a high-quality, lab-created material composed of silica and polymer. The polymer stabilizes the opal, making it significantly more durable and far less prone to cracking or crazing. These are common issues in natural opals that often make them unsuitable for everyday wear, especially in jewelry that sees regular use.

Natural opal is beautiful but fragile, and many jewelers advise against wearing it daily. Our synthetic opal solves that problem. It retains the vibrant look of natural opal while offering the strength and stability needed for long-term, daily use.

Thanks to its slightly softer composition, our synthetic opal is also easier to work with. It is ideal for turning, cabbing, inlay, and other artistic applications. It resists fading over time and holds up well against common chemicals such as acetone and alcohol.

How Our Synthetic Opal Is Made

Our synthetic opal takes approximately one year to grow in a highly controlled environment. During this slow and meticulous process, uniform silica spheres self-assemble into a highly ordered lattice through sedimentation. This internal structure is what gives opal its signature play-of-color.

Once the opal structure is fully formed, it is carefully dried using controlled conditions that preserve the integrity of the silica lattice. After drying, the porous material is impregnated with a polymer resin under vacuum. This stabilizes the opal’s structure, enhances its optical brilliance, and transforms it into a vibrant, gem-quality synthetic opal.

After the opal has fully formed, it is cut into rough stones, then crushed and sifted into four optimized sizes:

LARGE: 2 to 3mm pieces
MEDIUM: 1 to 2mm pieces
FINE: 0.3 to 0.5mm pieces
POWDER: Ultra-fine particles

How Lab-Created Crushed Opal Performs

Our product photos show Crushed Opal in its "wet" state, which is how it will appear once a binding medium such as adhesive, resin, or nail polish is applied. This is when the opal’s full vibrancy and depth of color are revealed, especially under natural lighting.

Please note:

Due to the crushing process, some pieces may appear less colorful when dry. (Incorporating the opal into your project will show its full potential)
Fine and Powder sizes may look lighter in their dry form but become much more vibrant when used.
Color appearance may vary slightly depending on your screen settings.

Crushed Opal Heat Resistance

Our Crushed Opal can tolerate heat up to 266°F (130°C). Use caution when applying heat, especially with tools like torches or soldering irons, and proceed at your own risk. This product is NOT compatible with borosilicate glass.

Reviews

Awesome color! It's a shade of soft pastel blue (not quite as green as the listing images.) The baby blue actually worked better for my design!

Oceanic

No doubt these are encrusted on Poseidon's Trident. A really subtle, sky/pale blue to start, then a spritely highlighter green takes over the stone. I would consider this to be more of an accent stone since the blue and green are in the same realm. Even though the green is opalescent, it blends warmly with the normal blue of it, and gives it a colorful, happy shine.

Wow! We couldn't have said it better ourselves :) Thank you Dave for your kind words! We really appreciate you and your support!!
