SAHO DualVeil 14K solid gold compared with 14K solid gold

A Signature, All Your Own.

Lab-grown diamonds in 14K solid gold. Worn with ease, styled with instinct. The finishing touch that feels unmistakably you.

Your lab-grown diamonds and 14K solid gold deserve a little downtime, too.

Beauty first. Diamonds second. Let perfume, lotion, and skincare settle before putting your jewelry on. Keep chlorine, bleach, and harsh cleaners away.

Sit this one out. Remove before swimming, workouts, or heavy lifting to protect the gold and diamond settings.

Keep the brilliance. Gently wipe away fingerprints and everyday buildup with a soft, non-abrasive cloth.

A little space helps. Store each piece separately in a soft pouch or lined box to prevent scratches. Fasten necklaces to keep tangles in check.

Read our full care guide.

Every order arrives in our satin jewelry box, beautifully packaged and ready to gift.

For a personal touch, leave a gift note at checkout and we’ll include a complimentary handwritten card.
