sure to contain some important and awesome facts about opal gemstones.
However, in this blog, we are going to give you a closer look at the Aurora Opal, its features,
and the most enchanting aspect that makes it even more special than other gems out there.
The Origin of the Aurora Opal
Follow us on
The Aurora Opal stone starts its cycle deep within the crust of the planet; water becomes
trapped in silica sediments. Across the centuries they accumulate and after millions of years,
with the right amount of heat and pressure, they turn into opal.
The Aurora Opal, in particular, is a result of this geological marvel and can exist in areas that
produce opals including Australia, Ethiopia, and Brazil. Every deposit implies certain
variations of the stone experience, due to the peculiarities of the conditions that existed when
the stone was being formed.
The Play-of-Color Phenomenon
The typical feature of the Aurora Opal is the so-called play-of-color – an effect that resembles
the spectacle of the colors that search for their reflection in the mirror. This happens because
when the light passes through the material composed of the extremely small silica spheres
forming the opal it will diffract.
The size and the position of these spheres define the diapason and the saturation of the colors
observed. In the Aurora Opal, this play-of-color is more vivid and this often depicts a range
such as the auroras with deep green and blue to the fiery red and purple.

Physical Characteristics
Aurora Opal is also an opal and hence it is without any crystal structure like all the opal
minerals. This gives it a unique set of physical characteristics: This gives it a unique set of
physical characteristics:
1. Hardness:
The Aurora Opal is rated between 5 on the Mohs scale. 5 and 6. 5. Although it is somewhat
softer in comparison with most of the other gems, it is still possible to maintain the stunning
appearance of the stone for many years if proper actions are taken.
2. Specific Gravity:
It splits well, and its hardness is approximately 5.5 to 6, while its specific gravity is 1. 98 to 2.
25, indicating its lightness. This property, together with the play-of-color that is brought out
so openly, makes it a preferred gemstone for pieces that do not impose heavy wear on the
client.
3. Fracture and Luster:
Follow us on
The common cleavage or fracture of the Aurora Opal is conchoidal, therefore when it’s broken,
the surface area is curved. It exhibits vitreous to resinous luster making it even more
attractive.
4. Water Content:
Another interesting fact about opals is that the Aurora Opal stone is not an exception – opals
contain up to 5% water, 3 % to 21%, to be exact. This water content is a part of the internal
structure of the opal and the diffraction of the light to form the play-of-color.
Optical Properties
It is here so to speak that the Aurora Opal comes into its own, quite literally as it happens. A
lot of people believe that the mystical optical properties of this stone remind them of a
Labradorite. Since the silica spheres within the stone are not uniform in size and distribution
it makes the play of light on the stone look dynamic and living.
This is not only an eye candy but physics and geology coming alive in close harmony.
1. Transparency:
Follow us on
Aurora Opals are mainly transparent to opaque. The openness depends on the degree of the
density of the stone: with transparent stones, the spectrum of the play-of-color is more
intensive.
2. Color Base:
They come in different colors of the body either white black or even can be transparent like
the aurora opal. A darker or black base color generally increases the contrast of play-of-color
making it more pronounced.

3. Pattern:
The play-of-color pattern can be different: freely branching and, at the same time, having a
rather large size of the color flashes; or it can be very delicate, with scores of points Joyce.
Each pattern is different, which partially defines the individuality of an Aurora Opal.

The Art of Crafting Aurora Opal Jewelry
It becomes a truly creative endeavor to turn rough Aurora Opal into a beautiful jewel that can
be worn. Due to the individuality of the stone per instrument, jewelers should ensure that its
organic colors are complimented.
1. Cutting and Shaping:
The Aurora Opal cutting can be described as a sensitive procedure. Due to it being relatively
softer and having higher water content, jewelers have to map each cut properly with the aim of
not causing the stone to crack but fully utilizing its play-of-color.
Cabochon cuts, in which the crown is flat and the pavilion is domed, are preferred to help
reveal more of the stone’s oil-sheen effect.
2. Setting:
Follow us on
The environment in which the Aurora Opal jewelry is placed also aims at guarding the stone
but at the same time revealing it in the best possible way possible. Bezel settings are widely
applied to keep the stone horizontal and minimize the chances of its destruction by embracing
it with metal.

Prong settings are also utilized, but one has to pay a bit more attention to make sure that the
stone is well-fixed.

​3. Design:
In Aurora Opal’s jewelry creations, many of the designs originate from the theme of nature
and the universe because of the stone’s ethereal properties. Chaste and at the same time
delicate designs in metals, including gold or silver, harmonize with the brusque colors of the
opal, producing jewelry that is both classic and fashionable.
Caring for Your Aurora Opal
1. Avoid Extreme Temperatures:
Temperature shock is also another factor that affects opal; if the temperature changes
suddenly, then it will crack. Laying the stone in direct sunlight or proximal to any
heat-producing source should also be discouraged.
2. Moisture Maintenance:
Follow us on
Since an opal has water in it if for whatever reason the opal dries up it can become very fragile.
Humidifying, for example by leaving your Aurora Opal in a wet environment or even
submerging it in water from time to time, will allow it to be preserved.
3. Gentle Cleaning:
If your Aurora Opal has been cleaned, wipe it with a clean microfiber cloth, a mixture of warm
water, and a drop of dish soap.
Do not use harsh chemicals for cleaning and never immerse the stone in ultrasonic cleaner.
4. Protective Storage:
When your Aurora Opal jewelry is not in use, it should be kept in a jewelry box or a soft pouch
and handy to avoid damage such as scratches.
