I'm not entirely sure I understand the question. Are you asking what a prong setting is or how you can acquire a prong set diamond engagement ring? In regards to the first option: a prong setting consists of a precious metal backing, or cradle, which the diamond is fitted into, and is then held in place by delicate, fine prongs. A prong stetting can feature up to 8 prongs, and the most common, traditional prong setting usually consists of 4 prongs. The prong setting is valued for its versatility and its simple sophistication and is perhaps the most popular engagement ring setting in today's diamond engagement ring market.
As for the second questions, you can get prong set diamond engagement rings at virtually any jewelry store since prong settings are so common, or you can design you own engagement ring setting.
A setting is the part of a ring that holds a stone. There are different kinds: Bar, Channel, Pave, Prong, and Tiffany settings (a prong setting with six prongs), among others. A jeweler can show you more.
Depending on the ring you will have to go to a jeweler, have him/her get an appropriate prong or bezel setting, have it soldered into the ring and then have your stone set into the setting. Don't forget to supply the correct size required as the ring will likely need to be cut to insert the setting and therefore will require resizing.
The post popular style of diamond engagement ring is currently the Princess cut diamond solitaire. Also known as the tiffany setting, the ring has one princess cut diamond set in a for prong setting. Most people are choosing white gold or platinum for this style.
Diamonds set into a four prong setting are fitted into a small metal bracket soldered to the ring's band. The diamond's culet (or its lower half) is placed inside the bracket and is held in place by 4 tiny metal prongs which grip the diamond's table (its top), thus holding the diamond secure.
You should take it to a jeweler if one of the prongs breaks to avoid inflicting further damage.
How you set a diamond depends on the type of setting. The most common type of setting is a prong setting which is set by cutting tiny grooves on the inside of the prong. The edge of the diamond will sit in these grooves. The prongs are then squeezed against the diamond to hold it in place.
A prong setting is composed of a thin metal backing that is in the shape of a cradle and 4 to 8 tiny, delicately fashioned metal prongs. A gemstone mounted onto a prong setting will have its culet (or bottom part) set into the cradle, and will be held in place by the metal prongs that gently grip the diamond's table (its top).
A prong setting will hold the stone in best.
If a prong breaks you'll need to bring it immediately to a jeweler to have it reattached. Usually you won't be able to tell that it's been broken.
A jewelery setting is called a setting. The noun, setting, can be modified by the type of metal, its purity, and perhaps a style of setting, and of course, the purpose of the setting.For example, 'This diamond is set in an 18 karat rose gold dinner ring [setting], surrounded by smaller diamonds."
