By the later 6th century, the best works from the south-east are distinguished by greater use of expensive materials, above all gold and garnets, reflecting the growing prosperity of a more organised society which had greater access to imported precious materials, as seen in the buckle from the Taplow burial and the jewellery from Sutton Hoo, c.600 and c.625 respectively. The possible symbolism of the decorative elements like interlace and beast forms that were used in these early works remains unclear. These objects were the products of a society that invested its modest surpluses in personal display, who fostered craftsmen and jewellers of a high standard, and in which the possession of a fine brooch or buckle was a valuable status symbol.
