FREQUENTLY ASKED QUESTIONS
Yes. The donut shape creates a lower profile and smoother wrist feel, especially in stretch bracelets.
Yes. Their flat profile makes them ideal between round beads or gemstone accents. They also have larger hole sizes to hide the knot.
Yes. Beads are precision cut and polished for consistent sizing. Minor tolerance (±0.1mm typical) can occur due to polishing, but they are manufactured for repeatability and batch consistency.
Opal appearance changes with lighting and viewing angle. Under point light, flash appears stronger and more directional. Under diffuse light, color appears softer and more even.
Photos and videos show typical presentation, but slight variation in pattern and flash is normal.
Yes. Astral Opal™ & Nebula Opal™ beads are well suited for permanent jewelry applications when properly mounted. Avoid direct torch exposure and extreme heat.
No. Both Astral Opal™ and Nebula Opal™ are color-stable under normal wear conditions. They do not contain water like natural opal and will not dehydrate or craze.
Avoid prolonged exposure to harsh solvents or direct flame.
Ultrasonic cleaners and aggressive solvents are not recommended. Clean gently with mild soap and water. Avoid acetone and strong chemical exposure.
Lab-grown opals provide:
- Consistent sizing and supply
- Stable structure (no dehydration risk)
- Lower cost per comparable visual impact
- Predictable performance in jewelry applications
Natural opal can be beautiful, but is more variable and higher risk for daily wear.
