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
