This compact crystal of pure carbon does not dissolve in any liquid at room temperature. Concentrated acids, at a very high temperature and pressure, may be able to decompose minute quantities of a diamond. Comparatively, a better job of dissolution is done when a solution of molten sodium hydroxide and sodium nitrate is heated and used. Researchers at the National University of Singapore have discovered a novel way to degrade, etch, or basically dissolve a diamond.

' Auction establishments can often provide for the highest profits, particularly when the old diamonds are valuable in every sense of the word. The bidding amounts may go higher until such time that your actual profits have more than doubled than expected. We generally don't recommend online auction sites in selling old diamonds, however.
The best way to ensure that you're paying that exorbitant price for the real thing, ask for the authenticity certificate, issued by a well-known grading authority. All reliable jewelers and prominent jewelry brands provide their customers with these certificates on purchase of diamond jewelry, even when not asked for.
