what is the one collection ring?

the one ring is a solitaire — one stone, one setting, no distraction. designed to let your chosen gemstone take the spotlight completely. available in two shapes: pear-cut for a softer, more fluid silhouette, and emerald-cut for a clean, architectural look. each ring is handcrafted to order in our los angeles studio in solid gold or platinum.

what is the difference between the pear-cut and emerald-cut ring?

the pear cut is a teardrop shape — pointed at one end, rounded at the other. it's softer and more romantic in feel. the emerald cut is rectangular with stepped facets — bold, structured, and graphic. both are set as solitaires in the same slim band. the stone shape is the only difference, so your choice comes down entirely to which silhouette feels like you.

what gemstone options are available?

both rings are available in 12+ gemstone options covering all twelve birthstone months — including diamond (april), emerald (may), moonstone (june), ruby (july), peridot (august), blue sapphire (september), and more. each stone is chosen for its quality and individual character. natural and lab-created options are available depending on the stone.

can this ring be used as an engagement ring?

Between sizes? Size up — rings can always be resized down.

Paper strip method

Cut a thin strip of paper about 10 cm long.
Wrap it snugly around the base of the finger you'll wear the ring on.
Mark where the paper meets itself with a pen.
Lay it flat and measure the length in millimetres — that's your circumference.
Find that number in the Size Chart.

Using a ring you already own

Place the ring flat on a ruler.
Measure straight across the inside opening in millimetres — that's your diameter.
Match it to the Diameter column in the Size Chart.

Good to know

Fingers swell slightly in warm weather — measure later in the day for the most accurate fit.
If you're between sizes, go up by half a size.

Free ring resizing within 6 weeks of delivery.

Two Year Warranty

We take great pride in the high-end craftsmanship of every Juwels & Co piece. Because we stand behind our quality, we offer a two-year warranty for customers within the United States, covering repair or replacement for any manufacturing defect. Due to international tariffs, import duties, and complex return-shipping requirements, our warranty is currently limited to US-based orders. These restrictions make it difficult to safely receive, repair, and return items across borders. We appreciate your understanding and remain committed to supporting our international customers with care and guidance.

Production Time

All our products are hand made in the USA. Our products are available within 2 - 4 weeks. If there is a product you would like by a certain date, feel free to contact us: info@juwels.co

Free Shipping & Returns

We offer free worldwide shipping. Once your piece is made, all orders are shipped within 1 to 3 business days. We have a 14-day return policy—your item must be in the same condition that you received it, unworn and unused. Import duties and taxes may apply to all orders except those shipped to the U.S., U.K., Germany, and Austria, and are the responsibility of the customer.
