Tektite

Tektite has poor toughness due to its glassy nature that lacks a crystalline structure, rendering it prone to cracking and chipping under stress or impact.

Tektite resists water, sunlight, and dry conditions well and can be cleaned easily. However, it should avoid heat and harsh chemicals to prevent damage. Overall, tektite maintains integrity under most daily use conditions.

Since 1963, the majority of known tektites have been known to occur only within four geographically extensive strewn fields: the Australasian, Central European, Ivory Coast, and North American.[8][9] As summarized by Koeberl,[10] the tektites within each strewn field are related to each other with respect to the criteria of petrological, physical, and chemical properties, as well as their age. In addition, three of the four strewn fields have been clearly linked with impact craters using those same criteria.

Varies; color can be caused by Fe2+ (for yellowish greens) and Fe3+ (for browns)

Tektite was used by the ancient Greeks and other cultures around the world as talismans, often worn or carried. The stone is still used for these purposes, often as a necklace. Meditation centers often display the rock, sometimes as small pebbles in a bowl. Larger stones are sometimes formed into decorative and spiritual artwork.

Due to its scarcity, tektite was prized as a very valuable stone that was thought to bring good luck, so it was often carved into amulets and talismans. According to a certain legend, tektite stones were the fallen emeralds from the sky. In some cultures, the stone was associated with fertility.

Tektite activates all of the chakras for complete healing. When used specifically on the Third Eye chakra, this stone can bring greater spiritual understanding. Its calming energy encourages peace of mind and relaxation. Tektite aims to improve self-discipline, provide a sense of purpose, and strengthen motivation.
