Opals aren’t shy about the magic they carry, and that’s part of their charm. From rainbows dancing in jelly opals to the flashes of color that light up black opals, opal refuses to be mundane.

It all goes back to how opals were formed, you see.


the Sanskrit upala, meaning ‘precious stone’, and later the Greek derivative Opallios, meaning ‘to see a change of color

Opals are the earth’s capsules of bygone days, with water as its magic wand. The elixir of life that can start civilizations, grows seeds into lush forests, and gives opals its cacophony of colors. Water is where it all starts.

Time creates layers of dust and stories over, captivating age-old wisdom. Settling into the nooks and crannies between dinosaur bones and secret voids the earth forgot. Time and pressure eventually eliminate the water, but the memory remains.

Opal chakra:

  • The fourth chakra - the Heart or Anahata chakra.

     A balanced heart chakra keeps your well overflowing with love. It helps you gain the ability to forgive and love yourself and others, even when you think you’ve reached the limit.

    The crown chakra is the bridge to the Cosmos (or the ‘umbilical cord’ to the divine). Located above our head (our crown), the Crown chakra keeps your heart and head open to any divine wisdom coming your way. Activate it whenever you feel spiritually jaded or losing out your sense of focus.

Tough Love level: 

5.5-6.5 Mohs scale of hardness with ‘very poor’ toughness. It’s best to use opal as earrings or necklace, especially for daily use. When used as a ring, make sure to take it off anytime you’ll be in contact with perfume, soaps, detergents, or the likes. Keep it off when you’re working out or doing anything laborious with your hands as opal is considered fragile. 

Common treatments: 

Smoking; oiling; resin treatment; synthetic opal. 

Smoking may be done on white or transparent opal to turn it black, which will fetch higher value. The black smoke will literally permeate into the opal’s pores, turning it black. It’s more common on Ethiopian opals, which unscrupulous sellers may market as natural black Australian opals.  

Oiling is done to fill cracks in the opal, and to increase its durability. Beware that this isn’t the most effective treatment to hide cracks and fissures. 

Resin treatment is done on thin slices of opals to give it more durability and size. When a thin slice of opal is assembled with a base and/or a clear top, it’s called doublet opal or triplet opal. These are sold for a fraction of the price, but are actually not a solid opal. To check whether or not your opal is a composite, look from the side and find any visible layers. Composite opals aren’t difficult to spot. Resin treatment is also done to seal moisture inside the rock and smoothen the pits, giving it a shinier appearance.

Synthetic opal is often made from plastic. It can be indistinguishable from natural opal, but synthetic opal might not have the hardness and properties of a real opal. Any trustworthy jeweler should disclose this information before selling it to you. 

Cleaning, care, and caution: 

Since opal loves water and is a soft stone, avoid ultrasonic cleaners and harsh chemicals. If you really need to clean your opal, use warm, soapy water, preferably made from natural ingredients, like our lerak jewelry wash! Read more about caring for your opals here.

Solid, doublet and triplet

Don’t let yourself get carried away by composite opals - these aren’t solid opals, but a thin layer of opal on wood, obsidian or ironstone. It’s like what veneer is to wood. They’re much less valuable than solid opal. 

Psst. we only stock solid opals for our designs.
