Tell Me About Opals
Posted by Lisa Ramos on
Although I design jewelry for a living, opals are the one gemstone I haven't worked with yet. An opals fragility has steered me away from designing with them, but their striking beauty is greatly admired. I started thinking more about opals when I recently came across an elegant opal pendant necklace I adored as a child. Over 40 years ago, my father had gifted my mother a one of a kind opal jewelry piece. The large oval opal pendant set in 18k gold with diamonds looked unbelievable for its age (pictured above). Its beauty and longevity were all results of my mother properly caring for her jewelry piece.
Seeing the pendant necklace after so many years brought many emotions. I couldn't resist touching the gem, looking at all of its colors and trying it on. As I wore the opal necklace I pondered about its history, unique beauty, its meaning and the many wonders about this incredible gem. The experience inspired me to write this blog and reconsider designing with opals.
