The New York Times article questioning the price of radium -- at US$120,000 per gram -- could be interpreted to mean that these two minerals may be competitors in the price wars. (Below.)
A diamond weighing a gram would weigh about five carats. If the stone were of a high colour, high clarity, and superior cut, it might cost about the same amount of money.
A fancy intense vivid stone with the same description would probably cost more.
Very possible, but the alloy (or the inter-metallic compound) is not obtained today.
yes
Gold:- Au Radium:- Ra
This compound was not obtained and studied; the chemical formula will be RaS (radium sulphide).
The short version is that, just as certain numbers of electrons give inert elements and certain other numbers give highly reactive elements, the stability of a nucleus is dependent on the number of neutrons and protons. Some isotopes of gold contain the proper numbers of nucleons to be stable; no isotopes of radium do, so radium is radioactive.
Radium is a chemical element, not a compound.
Radium is not a common commercial product.

All are metals, natural chemical elements.
Gold, chlorine, titanium, and used to be mercury

Gold is a very soft element which is combined with other elements to become hard. A pure gold jewel floats in water while a gold combined with other elements become densier.
Gold is not so reactive but has compounds with other elements.
Yes, many compounds of gold are known.
