Diamond Antique Ring Circa 1775
Georgian Diamod Ring with Rose Gold Band
7306

This wonderful early ring came from Boston Massachusetts. It has a circa date of 1775. The ring is set with seven rose cut, hand cut diamonds that are hand set in silver. Silver was the chosen metal of the time for setting diamonds because it complemented the fire of the diamonds. As in this ring, if gold was used it was in the background or the underside of the setting. The rings band is 18 karat rose gold. The settings of gold and silver were difficult metals of the period to blend. The higher temperature needed to heat the silver metal evenly over the entire item; it would have been pains taking to set all of these stones. The diamonds are set in a setting called “Collet set”. Collet setting is a style of setting a stone in which the stone is fitted in a circular “box” made from a thin metal band. When the upper edge is bent (rubbed) over the Girdle of the stone to secure it, it is known also as a “rub-over setting”.
The diamonds total 1/3 carat estimated weight.
After hearing someone ask an expert on TV the other day if diamonds were first used about the time of our Civil War, I wanted to give a bit of background on the diamond gemstone.
Diamonds, known for over 3000 years, were probably first found in India as loose stones associated with the sand and gravel of riverbeds For centuries they were thought to possess magical powers, no doubt because of their hardness and luster, and were kept, uncut, as sacred objects or important treasures of state by the religious and political leaders of the day. Being regarded as talismans, it was thought that they would lose their powers if they were altered in any way. It wasn't until the 11th century that diamonds were first worn, in their uncut form, as adornments. However, with the use of diamonds in jewelry, sometime in the 13th century it became known that a diamond's appearance could be enhanced by grinding and polishing of the rough crystal. This was achieved by polishing with diamond dust at angles varying slightly from those of the original octahedral faces to form a point cut. A major advance in faceting came about with the introduction of the polishing wheel, in the middle of the 14th century. This led the way for brighter diamonds with increased facet pattern complexity. In this same era the rose cut appeared. Rose cut diamonds were very popular in the 18th century. During the early 18th century, Brazil, the new center of world diamond production, gave rise to the old-mine cut, a forerunner of the modern brilliant cut having 33 crown and 25 pavilion facets, the same 58 facets as today's round brilliants.
The rings bands size is an 8, and can be resized it needed, without diminishing the value. The face of the ring measures 3/4 of an inch across, and ¼th on an inch tall. This ring was probably a forefinger ring; this was a popular style in this time period. A fashion taken from the Renaissance period, as they are usually a flatter style of ring, to be worn on the index finger. This is a ring that is approximately 230 years old. The ring is simply elegant to the overall look and a very good investment. This ring is in excellent condition and strong to wear. The insured value as of September 2012 is $4000.00
