About the Jewelry
Yes, you can. We have two physical stores where you are welcome to see our products firsthand. Please get in touch with us via email or phone call to make sure we have your desired product available for viewing. Remember, we aim to be as sustainable as possible, which means our jewelry pieces are usually not mass-produced but custom-made.
Absolutely. If you’ve got an idea, we’ve got the design team. Share your ideas with our bespoke team to create a unique piece of jewelry. All you need to do is send us an inquiry with your concept and images, if available. One of our designers will get in touch with you to discuss your design and provide you with a quote.
Once you approve the quote, we will source your chosen center stones and start crafting your piece in our workshop. The duration for this will be communicated to you and will depend on the complexity of the design. And remember, even if you love one of our pieces but wish for a slight alteration – that’s also possible! Simply get in touch with our specialists to find the perfect fit.
Yes. Our jewelry is made from alloyed precious metals to increase their strength and enhance their color. Each piece is hallmarked with three stamps – our unique workshop code (Ωι.27), a laser-engraved Diamond Lab logo, and a metal purity indicator.
We prefer 18k gold for its optimal balance of color, quality, and durability. While 14k or 10k gold jewelry has a lower percentage of pure gold and thus a fainter color, 24k gold, though purer and more vibrant, is more prone to damage due to its natural malleability.
Definitely. You can add any message you want to your ring free of charge. Be advised, however, that engraved rings are non-returnable. Also, if your ring needs resizing, the engraving will have to be remade.
Diamonds graded by GIA, GCAL, HRD, and IGI are laser inscribed on the girdle with an identification number and/or a unique symbol. This is a convenient way to identify a diamond, offering peace of mind when making a diamond purchase.
Yes, Diamond Lab offers a wide collection of stunning lab-created diamonds. They possess the same physical, optical, and chemical characteristics as our natural diamonds.
Yes. Lab-created diamonds share the same properties as natural diamonds, including their fire, scintillation, and sparkle. They are, indeed, real diamonds and nearly indistinguishable from natural diamonds with the naked eye.
The nature of the accent diamonds on your ring depends on the type of the center diamond. If the center stone is lab-created, the accent stones will likely be lab-created as well. Similarly, if the center stone is natural, the accent diamonds will also be natural.
Of course. If you’d like to see our rings from a different perspective or compare multiple rings, feel free to send us an email.
Yes, all the diamonds listed on our website are available for purchase.
Yes, they might slightly turn yellow over time. To provide 18k white gold with its bright white color, it is usually plated with rhodium. Over time, this plating may wear off, revealing the true color of white gold – a mildly buttery off-white. However, this can be restored by reapplying the rhodium plating.
Yes, all our 18k white gold pieces are rhodium-plated to provide a brilliant, white shine. If you prefer the natural warm tones of un-plated 18k white gold, please contact us. We can adjust this during your order placement.
Conflict-free diamonds are those mined and procured without causing human rights abuses, sparking civil wars, exploiting child labor, invoking violence, or inflicting environmental damage.
