The Dragon sq shield (g) is a Dragon square shield after being used with a Dragon sq shield ornament kit. The ornament kit is only obtainable as a reward from elite clue scrolls, or from trading other users characters. Like its regular counterpart, the shield required 60 Defence and completion of the Legends' Quest to equip.
It has the same stats as a regular Dragon sq shield, and serves no other purpose than making the Dragon sq shield look fancier. This shield along with the rest of the set are commonly thought of as gold-trimmed Dragon armour. Many players don't use this for fighting as it is more expensive than its regular counterpart and has the same stats. Rather, it is mostly used as a decoration in safe PvE or PvP situations.
