Gold Diamond Pair Watches

Made by Barraud, London. Of Huguenot origin there were several Barrauds working in the horological business from the mid-eighteenth century. The makers of this watch were probably Francis and Paul Barraud. Later, the firm became famous as chronometer makers and survived until late in the nineteenth century as Barraud and Lund.


The fusee driven movement has a verge escapement with an uncompensated balance. The spiral pattern on the back of the watch case was produced using a rose engine which mechanically engraved the case. This was then covered by a layer of translucent enamel.


This style of watch can be described as mechanical jewellery. The deep purple enamel and split pearl bezels were designed to appeal to feminine taste. Arabic numerals are used, a rare feature and the gold hands have diamond shaped tips.

This watch was worn to be seen, and is likely to have been hung on the end of a chatelaine, attached to a band at the waist.

Toughness of Diamond

Toughness relates to a material's ability to resist breakage from forceful impact. The toughness of natural diamond has been measured as 2.0 MPa·m1/2, and the critical stress intensity factor is 3.4 MN·m−3/2. Those values are good compared to other gemstones, but poor compared to most engineering materials. As with any material, the macroscopic geometry of a diamond contributes to its resistance to breakage. Diamond has a cleavage plane and is therefore more fragile in some orientations than others. Diamond cutters use this attribute to cleave some stones, prior to faceting.Diamond Toughness shows the Quality of the Diamonds.. Here Some Of the Beautiful Diamonds To Buy!!

Fashions in ornaments have undergone a great change in recent years, ornaments are made artistically and having less weight. The innate crave of the female heart for ornaments continues in despite social, economic and political and women continue to be zealous about ornaments.

Ornaments are used chiefly by women and children. Men hardly use any things ornaments now-a-days. Formerly, a gold necklace called sakhali, goph or kantha, a pearl ear-ring called bhihbali, a fold wristlet called poci and angathis (finger-rings) were the chief ornaments for men. Then came buttons, links, tie-pins and wrist-watches of precious metals. These are also used rarely now-a-days. Orthodox Jains wear ear-rings, gold chains and angathis.

Diamond Butterfly Ring


Seen as a symbol of nobility, perfection and immortality, jade has a unique place in Chinese culture. It has been used to make ritual utensils as well as other items such as seals, snuff bottles and penholders. Viewed as the essence of heaven and earth and a symbolic link between the two, it has been a custom in Chinese societies to place jade cicadas in the mouths of the deceased to comfort their souls and help with their "rebirth."


People also like to wear jade ornaments, as they are believed to have the power to protect the wearers from misfortune and bring good luck, while wearing the jade is also thought to improve its quality and color as it absorbs oil from the skin. It is employed for hat or waistband ornaments, inlayed on Sword handles and scabbards and crafted into hairpins and pendants. The carving of such jade ornaments can be as simple as shaping a jade "coin" or as detailed and complicated as can be imagined, but the method of attaching a piece to a hat, belt or necklace is usually quite simple.




Instead of the traditional Chinese jade and macramé design, Chang adds other precious and semi-precious stones like diamonds, rubies, black onyx and red agate to her jade creations, "assembling" all the parts together with precious metals like gold and silver. The result can be just a small accessory that enables the original piece of jade to be worn as a pin or pendant, or it can be as complicated as a butterfly with movable wings and antenna.

The centerpiece stone of Chang's designs is usually white jade from the Ming or Qing dynasties (1368-1644 and 1644-1911 respectively) collected by her husband Yang Ping-shih. Yang, a professor of entomology at National Taiwan University, started collecting jade nearly 30 years ago when, while preparing teaching materials for a class on insects and arts, he hit upon the idea of using a few small jade butterflies and cicadas to illustrate his lecture.
