Materials
At Bax, gold is not simply a metal, but the result of a perfect
chemical and artistic equation.
All our jewelry is made exclusively from 18-carat gold (750/1000
fineness). This means that every gram of metal is composed of
75% pure gold, while the remaining 25% consists of carefully balanced
precious alloys. It is this secret "recipe" that gives the jewelry
the necessary hardness for setting, wear resistance, and the specific
desired coloration.
Here are the technical specifications for our four gold variations:
18 CT YELLOW GOLD:
•
•
Technical composition: the alloy is obtained by combining 75% pure
gold with a balanced percentage of silver and copper. Silver
mitigates the redness of copper, while copper provides mechanical
resistance.
•
•
Characteristics: the result is an intense, warm, and deep yellow
that does not fade over time. Unlike plating, the color is intrinsic to the
metal. The final manual polishing enhances the gold's natural reflectivity,
creating a mirror-like surface ideal for making emeralds and rubies stand
out.
18 CT WHITE GOLD:
•
•
Technical composition: to 75% yellow gold, an alloy of "whitening"
metals such as silver and palladium (a rare metal from the platinum
group) is added, which neutralizes the natural yellow of the gold.
•
•
The finishing process: to achieve that absolute, vibrant ice-white,
the jewelry undergoes a galvanic bath of Rhodium (Rhodium plating).
Rhodium is a very precious metal that protects the jewelry from oxidation
and maximizes its brilliance, creating the perfect optical base for white
diamonds, making them appear visually larger and brighter.
18 CT ROSE GOLD:
•
•
Technical composition: while maintaining the 750 fineness of pure gold,
the percentage of copper in the remaining alloy is increased, and that of
silver is decreased. It is copper that gives the characteristic pink hue.
•
•
Characteristics: our specific alloy is designed to ensure color stability
over time. It is a tough, very resistant metal that offers a warm, vintage
aesthetic, particularly suitable for setting brown diamonds and colored
stones, creating a soft chromatic continuum pleasing to the eye.
18 CT BLACK GOLD:
•
•
Technical composition: it is a precious variant of 18-carat gold,
subjected to a surface treatment called black rhodium plating. This
process consists of applying a very thin layer of black rhodium—a
metal from the platinum family—which gives the jewelry an intense,
dark, and luminous finish•

•
Characteristics: this is not a simple painting, but a molecular bond on the
surface. The result is a deep and elegant color, similar to anthracite, that
combines the luster of noble metal with a modern, sophisticated, and bold
aesthetic. Ideal for those looking for an alternative to classic yellow or
white gold, rhodium-plated black gold expresses personality, style, and
character.
•
Maintenance note: being a high-tech surface treatment, black gold is a
"living" material that can evolve over time at points of greater friction,
revealing the soul of the underlying gold and telling the story of the wearer.
HAND POLISHING
Regardless of the alloy color, the final stage is what distinguishes Bax Jewels
from mass production. We do not use industrial tumbling machines (which
polish through indiscriminate mechanical friction).
Every single ring, bracelet, earring, and necklace is hand-polished by our
artisans with specific brushes and abrasive pastes. This allows us to reach
even the most hidden crevices near the stone settings, ensuring uniform
brilliance and a silky feel that only high jewelry can offer.
