Here are a list of basic terms that you will often come across in my blog. This is no way a complete list of terms but it should, nevertheless, help you learn more about (vintage) jewelry. These terms and more are provided in the Jewelry.com "Glossary of Jewelry Terms" website.
Facet -- Any flat polished surface of a diamond or gemstone. This style of cutting gives the stone many small faces at varying angles to one another. The placement, angle and shape of each facet are carefully planned and executed to show the stone's inherent beauty, fire, color, and brilliance to the fullest advantage.
Inclusion -- "Internal characteristics" apparent to a trained or professional eye at 10x magnification. Inclusions can be bubbles, crystals, carbon spots, feathers, clouds, pinpoints, or other impurities, or even cracks and abrasions. They are what make a diamond so unique, as a fingerprint does for a person.
Loupe -- Any small magnifying glass mounted for hand use, to hold up to the eye socket or attach to a pair of glasses.
Marquise shape -- A double-pointed, boat-shaped stone that is long and thin with gently curved sides coming to a point on either end. Marquise is part of the brilliant-cut family; ideally cut it has 58 facets.
Pave -- A type of setting where a number of small stones are set together. It literally means paved with diamonds.
Pear shape -- Term used to describe any diamond whose girdle outline resembles a pear shape. Ideally cut pear shapes have 58 facets.
Prong or claw setting -- The metal tip or bead that actually touches the stone and holds it into place. This setting usually consists of four or six claws that cradle the stone. Because this setting allows the maximum amount of light to enter a stone from all angles, it sometimes can make a diamond appear larger and more brilliant than its actual weight. This setting can also hold larger diamonds more securely.
