Precious Stones never go out of fashion, but be sure you have the perfect one. Like pearls, you will find three kinds: artificial, meaning made in a lab, and Imitation, natural, meaning dug out the floor; meaning produced in China. Almost all gems -- such as those mined out of the ground – are updated with laboratory procedures, such as radiation and diffusion: that's OK.
Synthetics are obviously more affordable due to their availability. And don't think that synthetic is just like a fake: these are gems, only grown in a laboratory. These are colored bits of plastic rather than fake.
Faceted Gemstones usually have greater clarity; the faceting allows light to pass through the bead and reveal its brilliance.
Many new stone treatments are developed to enhance the appearance and durability of gemstones. However, treatment may diminish the gem's value and might require special care to keep the gem's appearance.
Laboratory-created (artificial) stones are identical to natural stones but don't have their rarity and price; hence, laboratory-produced stones are less costly than naturally excavated stones.
In contrast, Imitation or "constructed" stones resemble natural stones in appearance but may be plastic, glass or other less precious stones.
Follow these Hints:
• Ask whether the gemstone is synthetic, natural, or fake.
• Ask whether the gemstone was treated at all.
• Learn how to use a jeweler's loupe (little magnifiers) to see inside the stone to assess if it's chipped or damaged in any way; ask the salesperson to educate you about the quality of the gemstone.
• Make sure that you receive everything in writing. A sales slip or evaluation listing the quality of the bead is considered a contract and is the only way of proving what you've been told.
• Read all guarantees and warranties before purchasing the Jewelry.
• Request a certificate of replacement price or appraisal listing the distinctive qualities of your gemstone to supplement your receipt.
Ask about the cleaning and maintenance of the gem.
