Curated answers to the questions we hear most — from diamond clarity to bespoke craftsmanship.

💎 Do you work with custom or heirloom jewelry?

Yes. At OLIVA by Gross, many of our most meaningful pieces begin with personal stories - a grandmother’s brooch, a family heirloom, a stone from a past memory.
We specialize in transforming sentimental jewelry into modern creations that reflect your taste and legacy.

🌍 Where is OLIVA by Gross located?

Our flagship atelier is based in Israel, where every piece is carefully designed and crafted.
But OLIVA jewels have been spotted worldwide - from Monaco to Melbourne, at the most prestigious weddings, luxurious parties, and high-end nightlife events.

✨ Do you ship internationally?

Yes. We proudly offer insured international shipping for all of our pieces, ensuring that OLIVA jewelry reaches you, no matter where you are in the world.

💍 Can I schedule a private consultation?

Absolutely. Whether you’re seeking a custom engagement ring or refining a family treasure, we offer one-on-one private appointments with our team - in person or virtually - to guide you through every detail of your creation.

🔎 How do I know your diamonds are real and certified?

Each diamond at OLIVA by Gross is hand-selected by our experts and accompanied by GIA or equivalent certification. Transparency, integrity, and quality are the pillars of our work. 
We also offer in-depth guidance so you understand every detail - from cut to clarity.

🛠 What if I need resizing, cleaning, or repair?

We provide lifelong support for your OLIVA pieces. From polishing to resizing, we welcome you back to our atelier for any ongoing care your piece requires. We consider every creation a long-term relationship, not a one-time purchase.

❤️ I want to propose - can OLIVA help with the ring?

Of course. Many OLIVA rings are tailor-made for life’s most intimate moments.
From repurposing a beloved stone to choosing the perfect setting, we’ll work with you to create a ring that’s personal, emotional, and unforgettable.

🕊 What sets OLIVA apart from other luxury jewelers?

OLIVA by Gross is a love story.
Founded by Nilly and Motty Gross, our brand was born from a shared passion for diamonds and craftsmanship.
Years later, the brand has evolved into a global name, rooted in authenticity, artistic precision, and emotional design. Every piece holds a story. Every detail is intentional.
