MATERIALS AND JEWELRY CARE
Sif Jakobs Jewellery factory is a member of the Responsible Jewellery Council (RJC), an international organisation that sets high standards for ethical, social and environmental
practices across the jewellery industry. This means our materials are part of a
responsible value chain, supporting responsible working conditions, local
communities and the environment.
LAB-GROWN DIAMONDS
Real diamonds created with advanced technology that mirrors nature’s own process.
Our lab-grown diamonds have the same brilliance, hardness, and durability as mined diamonds – but are created with a modern and more responsible approach.
14K GOLD
Crafted in 14 karat solid gold (585), designed to last a lifetime.
14K WHITE GOLD
Crafted in solid 14 karat white gold (585) with a rhodium finish.
The rhodium plating gives an exclusive, bright white surface.
925 STERLING SILVER
Crafted in 925 sterling silver with a rhodium plating that provides a bright and durable finish.
All our silver jewellery is nickel-free and complies with international quality standards.
18 CARAT GOLD
Crafted in 925 sterling silver and plated with 18 karat gold for a golden finish.
ZIRCONIA
Sif Jakobs Jewellery uses high-quality cubic zirconia, carefully selected for their clear brilliance and elegant appearance.
Cubic zirconia is a beautiful and durable alternative to diamonds and is cut to achieve maximum light reflection and shine.
FRESHWATER PEARLS
Freshwater pearls are semi-precious gemstones that form naturally in freshwater mussels.
We use naturally coloured freshwater pearls in our collections, selected for their organic beauty and unique character. Each pearl is unique in shape and tone.
WATCHES
Sif Jakobs watches are crafted in 316L stainless steel – both the case and the bracelet – making them durable and hypoallergenic.
All watches feature:
- 316L stainless steel
- Hypoallergenic materials
- Sapphire crystal (extremely hard and scratch-resistant)
- MIYOTA Japanese movement
- IP/Ion gold plating (0.5 MIC TIN + 0.1 MIC AU (1N14))
Sapphire crystal is considered the most durable material for protecting the watch dial from impacts and scratches.
UNIVERSAL JEWELLERY CARE TIPS
To preserve the beauty and finish of your jewellery, we recommend following a few simple principles:
Always make your jewellery the last thing you put on – and the first thing you take off.
AVOID CHEMICALS
Avoid contact with perfume, hairspray, hand sanitizer, lotions, and cleaning products, as chemicals can affect metals, plating, and stones over time.
AVOID WATER AND MOISTURE
Remove your jewellery before showering, swimming, exercising, gardening, or other water-related activities. Chlorine, moisture, and sweat can affect metals, coatings, and natural materials such as pearls.
CLEANING
Wipe your jewellery with a soft cloth after use.
If needed, rhodium- and gold-plated jewellery can be cleaned in lukewarm water with a small amount of pH-neutral soap. Rinse thoroughly and dry gently with a soft cloth.
STORAGE
Always store jewellery separately to avoid scratches – preferably in the original box or in a jewellery box with individual compartments.
FREQUENTLY ASKED QUESTIONS
CAN I SHOWER WITH MY JEWELLERY?
No, we recommend that you take off your jewelry before bathing, showering, taking a bath, going to the sauna, or using a sunbed. Steam, moisture, fragrances, and chemicals in soap and shampoo can cause materials to tarnish and become dull
CAN I WEAR MY JEWELRY WHILE WORKING OUT?
We recommend that you remove your jewelry before exercising. Sweat and alcohol in deodorants and disinfectants can react with metals, pearls, or stones, causing color loss and dullness. Chlorine and salt can also damage metals, so you should not wear your jewelry while swimming. There is also a risk of damaging the jewelry if worn during physical activity.
HOW OFTEN SHOULD I CLEAN MY JEWELLERY?
You should clean the jewelry you wear every day approximately once a week and other jewelry in your jewelry box about once a month.
HOW CAN I REPAIR THE CLASPS ON MY EARRINGS?
Earrings can be difficult to close if the clasp becomes bent during use. This can be easily remedied by gently pressing on the clasp, either upward or downward, to make it click back into place.
