Boulder opal Bracelets are one of our most popular bracelet category

The reason is that these bracelets are large size than most other types opal and they look so natural and earthy so they suit casual wear in jeans to everyday wear

Boulder opal is formed in ironstone and silica is formed on top of this or in veins, and this silica forms into opal colours over millions years

Both types make excellent bracelets. The fully faced boulder opal is used a s focal stone in a bracelet and other boulders that are not full faced opals also good in several joined together still give off beautiful colours in the ironstone

Boulder opal beads are made from this veined boulder or another boulder known as matrix. This matrix opal has colour veins

In the rough so when rounded and polished veins colour show form different angels and this is so attractive,. Black opal is too expensive to make into beads and now south Australian opal is also hard to find so we do not have Australian opal bead bracelets as we used to

This is the reason that boulder looks so good in bracelet as its value for money.

Also some manufactures use zircon which is a natural gemstone and use small ones to join bracelets together as adjustable straps that fit most wrists

Most beads are 8 to 1 2mm in diameter and show colours when wrist moves.

Another popular design is tear drop boulder opals joined end to end around the wrist and these have swing movement to help show colours off better and have silver claps to close on wrist
