Our materials

At Vondel Diamonds, we believe that true luxury begins with the choice of the right materials. That is why we work exclusively with precious metals and diamonds of the highest quality, carefully selected to retain their beauty for generations.

18 karat gold

Our jewelry is crafted from 18 karat solid gold – the perfect balance between luxurious appearance and durability. The high gold content (75%) gives our creations a rich color and timeless elegance, while the addition of precious metals ensures strength and wearing comfort.
We work exclusively with solid gold; never with gold on silver (vermeil) or gold plating. This way, you are assured of a piece of jewelry that retains its value and beauty for life.

14 karat gold

In addition to 18 karat gold, we also offer a selection of jewelry in 14 karat solid gold. With a gold content of 58.5%, 14 karat gold is slightly harder, making it particularly suitable for jewelry worn daily. It offers a refined look with extra durability, without compromising on quality or appearance.

Just like with our 18 karat collections, we work exclusively with solid gold; never with vermeil or gold plating. This way, you are assured of a piece of jewelry that retains its beauty, day after day.

Available colors:

• • Yellow Gold – classic and warm, for a rich appearance.

  • White Gold – modern and refined, with a subtle sheen.

  • Rose Gold – elegant and romantic, with a soft hue.

Platinum

For those seeking ultimate exclusivity, we offer jewelry in platinum (Pt950). This precious metal is known for its rarity, exceptional strength, and lasting whiteness. Platinum is hypoallergenic and ideal for daily wear, as it hardly wears down. A platinum piece of jewelry from Vondel Diamonds is an investment in lifelong beauty.

CVD-lab grown diamonds

The heart of every Vondel Diamonds piece is our diamond. We work exclusively with lab grown diamonds, produced using the CVD method (Chemical Vapor Deposition). This advanced technique perfectly mimics the natural growth process of a diamond, layer by layer, resulting in diamonds of exceptional purity and brilliance.

Every diamond we select meets our strict quality criteria:

• Clarity: VVS–VS

• Color: D–F

• Cut Quality: Triple Excellent

Thanks to this selection, each stone sparkles with maximum brilliance and is visually indistinguishable from a natural diamond – with the added benefit of being 100% conflict-free, sustainable, and ethically produced.

Certification and trust

Transparency and certainty are paramount to us. That's why all Vondel Diamonds' diamonds and jewelry come with a certificate from the International Gemological Institute (IGI):

• Diamonds from 1.00 ct: individual IGI diamond certificate.

• Diamonds under 1.00 ct: official IGI jewelry certificate with specifications on diamond(s) and precious metal.

This way, you always know exactly what you are buying and are assured of authenticity and quality.

Timeless value

By choosing 14 or 18 karat gold, platinum, and the finest lab grown diamonds, we create jewelry that not only sparkles today but will be cherished for a lifetime. Every material is selected with care – for you, for the future, and for the planet.

Vondel Diamonds – Luxury built on purity and perfection.
