How to Choose MediCrystal Belt

This short review of our FIR heating belts should be helpful to make a choice. Though all of them work similarly, there is some difference between gems used, construction, and functions available.

All MediCrystal® belts work fine for the lumbar, waist, lower back, or abdomen. 

Same as the mats, all belts provide adjustable heat in the range of 86°F~158°F (30°C~70°C). All of them come with extra layers for negatively charged ion generation. These are high-quality units using advanced EMF-free double silicon electrical heating elements with overheat protection by bimetal switches. 

"EMF free" means that the electrical heating elements warming up the crystals do not generate more than two milligauss (0.2 mG by testing) of electromagnetic fields, which is significantly lower than 5-20 mG of electric blankets and standard heating pads. 

Only the bimetals and connectors of the belts generate 2-4 mG of EMFs when the belt pad is heating up. But the connector is situated on the exterior pad surface, which does not contact the body. So an almost one-inch thick pad shields the body from the connector. Our newest models use in-line connectors on the controllers' cables to avoid any EMFs on the heated stone pad.

Though the device creates intense heat, the significant advantage is that you can use it to target a specific area of your body or focus on local applications without causing full-body hyperthermia and sweating. 

Of course, if you are healthy and have your doctor's approval, the belt can be used together with any mini or large mat for intensive therapy.

You can use the belt as a belly band for concealed wearing in non-powered mode on your waist under the clothes. Please put it on with a crystals pad on the front, and fasten the straps on the back. It is excellent for women during periods as well. 

Even when the heat is off, crystals emit gentle far-infrared light with 90.7% effectiveness using the human body's natural warmth. In the non-heating mode, the MediCrystal® belt can take away the excessive heat from the too-hot zones of our body and return this heat in the form of FIR radiation to those parts of our bodies, which need it.


Two of them have a similar appearance with reddish-brown luxurious and high-quality eco-leather human-made heat-resistant fabric and wave design pads with one triangular window showing crystals abundant under all the surface.

The belt consists of the strap with Velcro fasteners and our smallest standard 8" x18" (20x45 cm) or XL 8 "x21" (20x52 cm) MediCrystal® amethyst heating pad attached on the strap. The length of the straps are 55"x8" (140x20 cm) for the standard belt and 63"x8" (160x20 cm) for the XL. They fit waists up to 52" and 60" inches, respectively.

Both these belts are with detachable pads. They are great to focus either on the back or abdomen. The heated pad can be disconnected from the belt strap and used as a small amethyst mat for shoulders, knees, elbows, neck, hands, legs, and other parts of the body. It is light, portable, and easy to use and carry.

1. Amethyst belts for deep heating 

It combines two features to synergize effects: the FIR crystal rays for deep heat and negative Ions for relaxation.

2. Amethyst-tourmaline (75%:25% ratio) biomagnetic belts

These belts generate ultra-low-frequency (adjustable from 1 to 30Hz) magnetic waves in addition to FIR heating and ions. 

Tourmaline is a unique stone with pyroelectric and piezoelectric properties known to generate negative ions upon heating or pressure. 

Every 4th line of the Bio-Magnetic Belt detachable heated stone pad is infused with natural black tourmaline. The other 75% of stones are natural amethyst. All crystals are crushed to 3-9 mm and tumbled in drum machines to flatten any sharp edges. 

The third type of belts does not have a detachable hot stone pad, but it is long enough to wrap the lower back, sides, and belly altogether. 

3. ThermoGem® 3-gems biostimulation belts with additional biomagnetic PEMF coils and red light LEDs

MediCrystal® ThermoGem® Bio-Magnetic Photon belt comes with three types of natural gems. Mesh fabric affixes thousands of crushed amethyst, jade, and tourmaline and lines of ceramic tourmalines in place without glue by an artisan sewing process. 

A new digital controller allows you to operate PEMF (pulsed magnetic fields) and red light photon(only ThermoGem belts) functions either with infrared heating or separately. You can set the timer for 1, 4, 8, or 12 hours. If the temperature is more than 122°F (50°C) for longer than 3.5 hours, the auto-protection feature will decrease it to a safe level of 113°F (45°C). The controller enables one to cycle PEMF and photon therapies, repeating 15-minute and 30-minute procedures each hour for up to 8 hours continuously. You can select any frequency from 1 to 30Hz manually or set a program auto-changing frequency sequence.

The belt measures 55"x10" (140x25 cm) with a 37"x9" (140x25 cm) non-detachable heating area lined with gems. It is affixed to the lumbar area by adjustable straps with Velcro closures and special braces to achieve a comfortable and ideal fit for men and women of all ages.

Though some heavier than other belts, the ThermoGem® belt is still compact and portable. You can carry it with you everywhere you go. It works with a standard AC outlet, or you can preheat it for an hour, unplug it, and you're good to go for a walk or to sleep. Hot crystals will keep warm and emit FIR and ions for at least half an hour.

Also, we have vests (jackets), knee wraps, and mats in this collection.

Please let me know if you need any more information.

If used with common sense, gradually increasing temperature, intensity, duration, and frequency of procedures, any of our belts should work fine for everybody.
