Those who are into Thai magic or amulets should be familiar with Leklai, Lek-laay or Lek-sa-ming. Leklai also termed as the black jewel of Thailand. Real leklai is exceedingly hard to find and can fetch up to very high price. Lek Lai is known as "fluid metal" (流鐵) amongst Chinese collectors.
Information provided here is translated from Ajan Boon, Ajan Ya-Kong and Ajan Choom. It is a common belief in Thailand that leklai can move about freely and has power to overcome harms from weapon.
The Arjans (Masters) have divided leklai into 2 main categories:
1. The Thai hermits will gather some material and use their meditative power to turn fluidic leklai into greenish rock formation.
2. The Koth Leklai (the oldest leklai) can be seen hanging out on cliffs. If people go into deep jungle can still get them.
If a leklai is dipped into natural honey, it can turn into dark brown in color.
Now that you know how a “real” Lek Lai looks like. You will need to depart on a trip in search for Lek Lai. My last information was that real Lek Lai is almost extinct; if found will be very difficult. Well, we will never know when our luck strikes.
