Double Black and Gold Necklace with Pendant - Aztec Coin
I handcrafted this double necklace , creating a distinctive and elegant composition. It is composed of diamond-cut black spinels . This special cut gives the stones a beautiful, intense shine that catches the eye. The piece is complemented by a distinctive pendant – the Aztec Coin .
All elements of the necklace are made of the highest quality silver covered with a thick layer of pure 24k gold .
I personally selected the stones, ensuring their perfect appearance. The layered design of the necklace makes it a complete, finished look that looks stunning on the neckline.

Gilding and Finishing
I create my designs from 925 sterling silver , which I plate with 24-karat gold in cooperation with a renowned Warsaw studio.
I use 1-2 micron thick gold plating— a much thicker layer of gold than most brands offer. This makes the coating more durable , less prone to abrasion, and maintains its beautiful shine for years —without darkening or dulling.
I additionally protect each element with an anti-tarnish layer, which protects against dulling and allows you to enjoy the noble finish for longer.
I craft each necklace with meticulous attention to detail — I hand-select all the stones, choosing them so that they not only look beautiful together but also sit harmoniously on the neck. This ensures each design is refined, elegant, and unique.

Frequently Asked Questions
The workmanship and quality of the jewelry
Yes. The jewelry is handcrafted with attention to every detail. All stones are carefully selected for quality, color, and shape, and each design is created with durability, aesthetics, and comfort in mind.
Yes. I personally select only the highest quality natural stones—carefully selected for color, purity, and structure.
The quality of the stones is demonstrated by their color, natural brilliance, and the uniformity and durability of their structure. Each necklace is crafted from stones selected with meticulous attention to aesthetics and overall harmony, ensuring that the jewelry will delight not only today but also for years to come.
The jewelry is made of 925 sterling silver, coated with a thick layer of gold, 1-2 microns thick. This is significantly thicker than many brands that use very thin coatings. This makes the gold plating more durable, resistant to everyday wear, and retains its color for a long time.
Additionally, the anti-tarnish layer protects the jewelry from dulling and darkening by slowing down the natural oxidation processes of silver.
Yes. I place great importance on ensuring that the necklace you order is as close as possible to the one you see in the photos. Each design is created using the same pattern and with the same attention to detail.
It's worth remembering, however, that pearls and natural stones are natural creations, so they may vary slightly in shape or shade. These subtle differences do not affect the character or aesthetic of the jewelry and never deviate significantly from the presented design.
The jewelry is made of flexible, 16-strand steel cord . It is very durable and yet drapes beautifully, ensuring the jewelry maintains an elegant and natural appearance on the neck.
Care and use
Bathing with jewelry on is not recommended—not in the shower, pool, or ocean. Chlorine, salt water, and frequent contact with moisture can cause gold plating to dull.
Jewelry can be gently washed occasionally in lukewarm water with a little soap. This will remove natural deposits from the leather and restore its fresh shine. After washing, dry it thoroughly.
Service and authenticity
Yes. It is possible to repair or refurbish Ula Sienicka jewelry. However, we do not provide repair or refurbishment services for jewelry from other manufacturers.
Yes. Each piece of jewelry comes with a certificate of authenticity.
