Settlement funds are liquid and unencumbered funds. It is not just assets minus liabilities. From your list above, the fixed deposit, your and your wife's savings and the surrender value of LIC qualify as settlement funds. Your and your spouse's provident funds also qualify as settlement funds IF you can withdraw them in cash on demand. Jewelry would not count.
Second, you cannot represent borrowed funds as settlement funds. If you can't show the required settlement funds out of your own money you don't qualify for FSW. If you represented borrowed funds as your own in your original application, you committed the criminal offense of misrepresentation and if the reviewers discover it you will be rejected and banned from Canada for 2 years or longer. It is possible that the local VO will ask you for 6 months or more of bank statements to verify.
