Crystal or Crystal AB? Crystal gives a clear, bright sparkle; Crystal AB adds shifting iridescent reflections. When choosing a tooth gem, compare the two at the same size, in daylight and at a normal viewing distance. Finish alone says nothing about application safety or how long a gem will stay in place.
What does AB mean on a tooth gem?
AB stands for Aurora Borealis. In crystal terminology it describes a surface effect that changes the way light reflects. Preciosa's catalogue distinguishes the colour of the glass from effects applied to its surface. Crystal looks clear; Crystal AB can show pink, blue or golden tones as light and angle change. It is not an opal or a different base material.
Which look is right for you?
Crystal for a clear point of light
Preciosa Crystal suits a clean, transparent sparkle that pairs easily with other colours and shapes. Size and placement remain the main visual choices. Even a small gem may be noticeable in some lighting.
Crystal AB for iridescent reflections
Preciosa Crystal AB brings a changing sheen without committing to one colour. Its appearance can differ between daylight, indoor light and photos. No finish guarantees the same effect on every smile or in every picture.
How to compare before buying
- Match the size. Both Preciosa ranges list options from SS02 to SS09; comparing different sizes may distort the visual difference.
- Use two lighting conditions. Look near a window and under the light where the gem will usually be seen. A flash photo is not enough.
- Consider the whole design. Crystal can be a neutral base; Crystal AB can provide a focal point. Keep each element readable.
- Check measurements. Our tooth gem size guide covers millimetres, tooth proportions and cleaning space.
To compare both finishes across sizes, the 120-piece Crystal and Crystal AB assortment includes six sizes from SS03 to SS09. Check the selected variant and live stock before ordering.
Keep the oral-health precautions in view
Neither finish is safer simply because of its colour. Tooth condition, bonding method, hygiene and removal matter more. The American Dental Association advises against tooth gems because of possible harm, including plaque accumulation, gum irritation and enamel damage. Seek a dentist's advice before application if you have pain, unexplained sensitivity, a damaged tooth or irritated gums. Have persistent discomfort or a loose gem assessed; do not pull it off yourself. This is general information, not a diagnosis.
Frequently asked questions
Is Crystal AB another material?
No. AB names an iridescent finish on a crystal. It is not a promise about retention or suitability for a particular tooth.
Which one should I choose for a first design?
Compare Crystal and Crystal AB in the same size at a normal viewing distance. Then consider placement and whether the surrounding area can be cleaned.
Can the two finishes be combined?
Yes. Start with a few well-spaced pieces and keep the application precautions in mind.
In brief
Choose Crystal for clear sparkle and Crystal AB for shifting colour. Compare like with like, then explore the available Crystal and Crystal AB sizes for your design.
