Crystal or Crystal AB? Crystal gives a clear, white, crisp 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 subtle point of light
Preciosa Crystal suits a clean, transparent sparkle that pairs easily with other colours and shapes. Its transparency puts size and placement in the foreground. “Subtle” is relative: even a small crystal may be noticeable depending on the lighting and the smile.
Crystal AB for iridescent reflections
Preciosa Crystal AB adds an iridescent touch without committing to a single colour. It is an appealing option if you enjoy seeing the gem change appearance in daylight, indoor lighting and photographs. The perceived intensity varies: no finish guarantees the same effect on every tooth or in every photograph.
How to compare before buying
- Match the size. Both Preciosa ranges offered by Tooth Gems World list options from SS02 to SS09, depending on the variant; 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 visually clear.
- 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. These risks deserve to be taken seriously, even with a small gem. 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 a colour or a different 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. Choose the finish whose look you prefer, then check placement and whether the surrounding area can be cleaned.
Can the two finishes be combined?
Yes, to create varied reflections. 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 iridescent reflections. The comparison is fairer at the same size and in the same lighting. To turn the desired look into a concrete choice, compare the available Crystal and Crystal AB gems, then select the size that suits your project.
