Introduction

 

Gem Beads of Jetavana
Some natural and synthetic beads of Jethawanaya bead collection

Beads were used as bodily ornaments by ancient people. Bead making is an art and a variety of materials like stones, gems, corals, shells, amber, wood, metals etc have been used since prehistoric time (Dubin 1987). The use of natural materials varied from region to region, country to country and place to place. Later the bead making process has been developed as an industry with better knowledge and advanced technology that created synthetic beads and properly faceted natural beads. After the beginning of long distance trade, knowledge and techniques of bead making were circulated and different kinds of materials and beads were distributed around the world. As a centre for trading in ancient times, Sri Lankan culture was enhanced and gained different techniques, materials and beads from different countries. Sri Lanka is rich in raw materials for making either natural or synthetic beads.

Ancient chronicles of Sri Lanka have┬ámentioned the use of gems as decorative┬ámaterials from ancient times (Mahavamsa 300┬áAD, Thupavamsa 300-600 AD). Gems, are┬áminerals which┬áhave specific characteristics.┬áBeauty defined by its colour, degree of┬átransparency, lustre, reflective effect, rarity┬áand durability of a gemstone decide the┬áclass of a gemstone, indicating if it is either┬áprecious or semiprecious. The main gem┬ávarieties found in Sri Lanka are Corundum,┬áChrysoberyl, Zircon, Garnet, Tourmaline,┬áBeryl, Moonstone, Topaz and Quartz family.┬áSri Lankan people have used gems not only┬áto create jewellery but also to decorate royal┬ápalaces and religious places. One of the┬ábest examples is the ÔÇ£Pabalu WeheraÔÇØ in┬áPolonnaruva which was said to be decorated┬áwith beads. There are evidencs of using gems┬áfor making beads. In subsequent periods,┬ábeads were also manufactured synthetically.
