Lakshmi is identified by the lotus buds in her upper hands. The lower hands are in Abhaya (protection) and Varada (boon-bestowing) mudra.

Some of the authors identify her as Vira-Lakshmi.

Lakshmi is the Goddess of Wealth and is a consort of Vishnu.  Note the breast-band (Katchbandha) identifying Lakshmi.  She is sitting on an inverted lotus-pedestal, which in turn is supported by a rectangular base.

A stand-alone Lakshmi Vigraha is not very common.

This Vigraha is most likely from Tamil Nadu. It is well-worshipped Vigraha and may date to the seventeenth century or earlier. It is about 4.5 cm in height.
