Embellish the Everyday

SINKU was created on a journey to find sustainable, ethical, and high-quality jewelry you can buy and wear everyday.

Wear Your Wild Side

Made for layering or to stand alone, SINKU’s elevated, delicate, pieces are designed to bring out your wild side as you embark on every adventure.

Our Gold Standard

Each diamond is custom-created from seed to stone, handcrafted, and paired with 14k gold that will never oxidize, or discolor. You can wear it everyday and hold on to your piece forever.

Our Commitment to the Planet

With sustainability at the forefront of our business, we are committed to carbon neutrality and using only 100% recycled or fairmined gold in each of our pieces.

Conflict-free, Always

Our diamonds are lab-grown, from seed to stone, making them 100% conflict free, so you never have to feel guilty about where your jewelry is coming from.
