A prong setting is the simplest and most common type of setting, largely because it uses the least amount of metal to hold the stone in place, displaying most of the stone and forming a secure setting. Generally, a prong setting is formed of a number of short, thin strips of metal, called prongs, which are arranged in a shape and size to hold ...
A prong set diamond in a gold ring.. Prong setting or prong mount refers to the use of metal projections or tines, called "prongs", to secure a gemstone to a piece of jewelry.A prong setting is one component of what is known to jewelers as a head, a claw-shaped type of binding (typically three, four, or six individual prongs per head) that is welded or soldered to a jewelry item to mount (or ...
Tension ring. A tension ring is a type of finger ring that holds a gemstone in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone, and tiny etchings or grooves in the metal create a shelf that supports the gemstone's edges.
Ruby ring. A ring is a round band, usually made of metal, worn as ornamental jewelry.The term "ring" by itself denotes jewellery worn on the finger; when worn as an ornament elsewhere, the body part is specified within the term, e.g., earrings, neck rings, arm rings, and toe rings.
Bezel settings use a type of elevated collar which wraps the rim of the diamond in a complete metal edging. This type of diamond ring setting is the most secure fastener for the stones. The bezel setting also protects the diamond better than other types of settings, such as the prong setting. A flush setting for diamond rings is a variation on ...
Generally it will need to be viewed loose under a gemscope to see the pattern very well. Although the hearts and arrows property is indicative of a top-tier cut, it does not always mean the diamond will be the most brilliant. Optimal facet placement is the key to brilliance and more important than facet patterning.
Nickel alloys are hard and strong, and therefore good for rings and pins. Gold-palladium alloys are soft, pliable, and good for white-gold gemstone settings. The strength of gold-nickel-copper alloys is caused by formation of two phases: a gold-rich Au-Cu, and a nickel-rich Ni-Cu, and the resulting hardening of the material. [3]
Less significant inclusions are ignored for the purposes of setting the grade; however, they may still be plotted onto a diamond plot chart. [2] Accurate clarity grading as with other grading steps must be done with the diamond "loose", i.e. not set into any mounting.
