Buyers find this extender handy for adjusting the length of a necklace, with plenty of eyelets to choose from. Some note the chain is on the thin side, so it does not suit every necklace.

Real 14k Gold
Real 14k Gold

In the TOV atelier, we work with real 14k gold. It is the source of excellence, the essence of your everyday shine. Each piece is made by hand and crafted with the utmost precision, following international goldsmith standards. For you.

REAL 14K GOLD Never plated. Never vermeil. No base metal.

Real gold makes top-quality jewellery. There is no other metal underneath, so there is no thin gold layer that can wear off.

Real gold is made to last, unlike, for example, gold-plated, where the gold layer can tarnish easily. TOV gold stays vibrant and is hypoallergenic, so gentle on your skin.

14K GOLD For Shine. Forever.

We craft our 14k pieces from real gold, chosen for its beautiful color, lasting shine and everyday durability. Its balanced composition makes 14k gold strong enough for daily wear while keeping the rich, luminous look that makes real gold so special. Durable, timeless and made to shine with you. Forever.

CERTIFIED GOLD Proven Quality

All TOV jewels come beautifully boxed. You receive a digital Certificate of Authenticity. This certificate confirms that your TOV is handcrafted to internationally recognized goldsmith standards, ensuring a genuine, high-quality item. Each piece also features an imprinted legendary TOV signature and a 585 hallmark to verify the pureness of the gold. Yes: TOV is bright, TOV is certified. It’s true love.

GOOD GOLD Straight from the maker

We work directly with our goldsmiths, with no middlemen in between. So more of what you pay goes into the gold itself. More gold for your money.

You want to know more. Of course, you do! Visit the Gold Guide and get to know all there is to 14k gold.

Digital Certificate of Authenticity

After your order you receive your digital Certificate of Authenticity as a PDF by email. Because it's digital, it's easy to find again and always at hand as proof that your jewellery is real gold. Diamond jewellery also comes with a diamond certificate.

Warranty

No sweet talk. You want hard facts. You got 'em.

2 YEAR WARRANTY The future is yours.

We give a 2-year warranty on all jewellery, and 1 year on stone settings and how clasps work. The warranty does NOT apply to: breakage or loss, to damage due to improper use, to damage due to a modification or repair by a third party, to damage from water, fire or normal wear and tear, such as scratches, to discoloration due to high acidity of the skin, the use of water, perfume, soap, lotion or hairspray and to discoloration due to cleaning with chemical means.

REPAIRS Stay perfect.

You want your TOV to be perfect again but the warranty is not applicable? Worry not. Sure we can help. Your TOV problem is our TOV problem. Simply tell us what’s up and show us some pictures. We study them, determine if repair is useful and take it from there. See more on repairs here.

14k gold is what we love. It appears brighter than 9k and is much stronger than 18k. 14k is the magic number: it is highly durable and rich in colour. Scuffs and scratches aren’t really an issue. It is an excellent choice. Nice to know: real gold, no base metal underneath. No sugarcoating. It makes it way more durable and keeps it hypoallergenic and gentle on your skin.

CERTIFIED Proven Quality

All TOV jewels come beautifully boxed, and you receive a digital Certificate of Authenticity. This certificate details your diamond's exact cut, color, clarity, and carat. It ensures you're investing in a genuine, high-quality item that meets industry standards.
