LIUANAN 108 Mala Beads 8mm Natural Bracelet Healing Gemstone Yoga Meditation Hand Knotted Mala Prayer Bead Necklace

Is this actual turquoise?

Are they knotted between beads?

Are these "Natural Gemstone" perhaps made of any synthetic, chemist made, unnatural materials besides "natural" turquoise minerals?

Is there any metal on the natural turqoise mala wrap necklace?
