Authentic Italian silver should be stamped with a hallmark indicating the purity of the silver (e.g. 925 for sterling silver). Additionally, the item may bear the manufacturer's mark or a country of origin stamp such as "Italy."

To identify real gold jewelry, you can look for hallmarks indicating the gold content, such as "14k" or "18k."

Yes, raw uncut fire opal can be valuable, especially if it has a high-quality color play or iridescence. The value also depends on factors like size, clarity, and origin of the stone. It's recommended to have it appraised by a professional gemologist to determine its exact value.

One of the persistent myths concerning opal is that they bring bad luck or even death.

This idiotic myth came into existence following the publication of Walter Scott's book: Anne of Geierstien in 1829. In Scott's novel the Baroness of Amheim wore an opal talisman with supernatural powers. When a drop of holy water falls on the talisman the opal turns into a colorless stone and the Baroness dies shortly after. Due to the popularity of Scott's novel, people came to associate opals with bad luck and death.

Fortunately most modern folks (but not all) discount this myth and have come to prize opal as the "queen of gemstones"

Tanzanite is typically more expensive than dark blue sapphire due to its rarity and unique color. Tanzanite is found only in Tanzania, while sapphires are available in various colors and locations, leading to a broader range of price points.

Opal is known for its play-of-color, which is a unique iridescence that displays a rainbow-like spectrum. This effect is caused by the diffraction of light as it passes through the tiny spheres or layers of silica within the stone. Opal's transparency can range from opaque to translucent, with the most prized opals being the ones that exhibit a high level of play-of-color against a transparent or translucent body.

Precious stones like sapphires and rubies are heat treated to enhance their color and clarity. This process can improve the overall appearance of the gemstone and make it more desirable for use in jewelry.
