Dakshinavarti Shankh

  The Dakshinavarti Shankh, or Sri Lakshmi Shankh, is a sacred Hindu object otherwise known as the Conch shell with a reverse-turning spiral. When held with the spout pointed up, the conch's spiral will turn to the right (Dakshinavarti) rather than the far more common variety which turns left (Vamavarti).

What is the Correct Way to Check Repeatability in Balances?

Genuine v/s fake

Traditionally this shell is a member of the family Sinistral turbinella pyrum, although other right-turning shells such as the Lightning Whelk, or Busycon Contrarium, are often mistakenly sold and worshipped in place of the genuine Shank. Genuine Lakshmi Shank must be a Conch, not a Whelk, and the real Lakshmi Shank will have 3 to 7 ridges in the conch cavity. Whelk shells have no ridges, being unrelated to Conch.
 

Origin

While genuine Dakshinavarti Lakshmi Conch are only found in the Indian ocean, between Myanmar (Burma) all the way to Sri Lanka. The imitation (Lightning Whelks) mostly come from North America.

Rarity

Real Lakshmi Conch (right side spinning) are estimated to occur only one per 100,000 conch shells; but Lightning Whelk always open on the right.

Powers ascribed

The Lakshmi Conch is said to bring all manner of blessing, but particularly material wealth, upon the owner. Ritual use may include bathing deities, drinking from the conch, or the use of mantras oriented to goddess Sri Lakshmi.

Current Value

Indian Rs. 3,000 to 6,000 per gram, depending on size, type and quality
