I’m looking for example of two goods/wealth that demonstrate inverse/negative correlation. For example if price of A rises then price of B falls. May be it is oil or gold prices along with some other wealth. Or may be some share prices (stocks) of some two companies. I can’t find example of such negatively correlated prices data.

U.S. equity market returns and U.S. Treasuries returns exhibit strong negative correlation (roughly -35%) over all time frequencies for sufficiently long time horizons. We attribute this inverse correlation to the fact that Treasuries are "safe-haven" assets, while equities increase in price as risk premiums decline.
Your question mentions price data. Your correlations will improve if you look at log-prices or returns.
There are many other examples of positive and negative correlations in finance, though many can prove ephemeral: utilities stocks and interest rates, long interest rates and life insurers, gold miners and gold prices, airlines and oil prices, and so on.

Have you tried Google? By copying a part of your question into Google I was able to find several examples. The best one may be this site which lists 20 positively and negatively correlated stocks for any stock you pick:
