Our Materials

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

18 carat 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 comfort.
We work exclusively with solid gold ; never with gold on silver (vermeil) or gold plating. This way, you're assured of a piece of jewelry that retains its value and beauty for life.

Available colors:

• Yellow gold – classic and warm, for a rich look.

• 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 everyday wear, as it hardly wears away. 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 (Chemical Vapor Deposition) method . This advanced technique perfectly mimics a diamond's natural growth process, layer by layer, resulting in diamonds of exceptional clarity and brilliance .

Every diamond we select meets our strict quality criteria:

• Brightness: VVS–VS

• Color: D–F

• Sharpening quality: Triple Excellent

This selection allows each stone to shine with maximum brilliance and be visually indistinguishable from a natural diamond – with the added benefit of being 100% conflict-free, sustainably and fairly produced.

Certification and trust

Transparency and certainty are our top priorities. That's why all diamonds and jewelry from Vondel Diamonds 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 jewellery certificate with specifications regarding diamond(s) and precious metal.

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

Timeless value

By choosing 18-karat gold, platinum, and the finest lab-grown diamonds, we create jewelry that not only sparkles today but is cherished for a lifetime. Every material is carefully selected—for you, for the future, and for the planet.
