Delphine — Round Ring

Yes. Lab-grown diamonds are real diamonds in every sense, with the same physical, chemical, and optical properties as natural diamonds. The only difference is how they originate — they are created in advanced laboratory conditions instead of being mined from the earth, with the same quality, brilliance, and durability.

The only difference is where they form. A natural diamond forms deep inside the earth over millions of years and is mined from there; a lab-grown diamond is created under conditions that replicate that same process, in far less time.

In composition, hardness, light refraction, and brilliance they are identical, and they cannot be told apart by eye. Lab-grown diamonds are also sent to a gemological laboratory and certified for color, clarity, cut, and carat weight.

Every diamond at Marabu is a lab-grown diamond held to a single standard: VS1 clarity or higher, F color or higher, and an Excellent cut.

VS1 clarity means that even at 10x magnification the inclusions are tiny and hard to find, and to the naked eye the stone is completely clean. F color sits within the colorless range (D–F) — the highest tier of the color scale. An Excellent cut is the top grade for proportions and polish, and it is what creates the brilliance and light return.

In designs with a fancy-color center stone — pink, yellow, or blue — grading follows the intensity of the hue rather than the white color scale, and the white side stones meet the same standard.

Yes. Every Marabu piece is made of solid 14K gold — not plated, not gold-filled.

Most designs can be ordered in white gold, yellow gold, or rose gold, and the choice is made on the product page before adding to cart.

In most cases, yes. Write to us and we'll arrange the exchange — hello@marabujewelry.co.il or 054-3975116, between 10:30 and 16:30.

As long as the tag has not been removed and the piece has not been worn, you also have the statutory right of cancellation within 14 days of receiving the jewelry. This right does not apply to a piece made specially to a custom size or special request. Full details in our returns and exchanges policy.

Yes — that's part of our customization. You can increase the center-stone carat weight, change the cut, or adjust the side-stone setting.

Tell us what you're looking for and we'll come back to you with a proposal and timeline — hello@marabujewelry.co.il or 054-3975116.

Yes. Every piece comes with a one-year warranty from the date of delivery, covering manufacturing defects in the goldsmithing and setting — a failed weld or clasp, a loosened setting, or a stone falling out under normal, careful use in line with the care instructions.

If a defect covered by the warranty is found, we will repair or replace the piece. The warranty does not cover loss, normal wear, scratches, impact or dropping, or work done by anyone not authorized by us. Claims require proof of purchase and sending the piece in for inspection. Full details in Section 11 of the site terms.

For routine cleaning: lukewarm water with a drop of mild soap, a soft brush used gently around the setting, and drying with a soft cloth.

It's best to remove your jewelry before sports, sea, and pool, and before creams and cleaning products, and to store it separately from other pieces so it doesn't scratch or get scratched. A diamond that looks dull is almost always a dirty diamond — not a flawed one.
