Questions about this piece

How long is the chain?

The chain is 18 in long. It falls at the collarbone, the most common pendant length.

Are the diamonds lab-grown?

Yes. They are laboratory-grown diamonds, chemically and optically diamond, and labeled as lab-grown on the receipt.

What does CTW mean?

CTW is total carat weight: the combined weight of every diamond in the piece. One carat is 0.2 grams.

Is sterling silver real silver?

Yes. Sterling silver is 92.5% pure silver, alloyed with a small amount of other metal for strength.

Will sterling silver tarnish?

Yes, slowly, with air and skin contact. Store it in a closed pouch and polish it with a silver cloth. Rhodium-plated silver resists tarnish until the plating wears.

Is the gold color permanent?

Plated, vermeil, and gold-filled finishes are layers over another metal. Gold-filled layers are thick and last for years; plating is thinner and wears gradually with friction, lotion, and chlorine.

Will white gold turn yellow?

The rhodium plating on white gold wears slowly with daily use and can reveal a warmer tone underneath. A jeweler can re-plate it quickly, usually every one to three years.

Can I wear it in the shower or pool?

Take it off to swim, bathe, or use a hot tub: water, soap, and chlorine wear plating faster, chlorine and salt water speed tarnish on sterling silver, chlorine in pools and hot tubs can weaken karat gold alloys over time, and soap and lotion film dulls diamonds. If it gets wet, rinse in clean water and pat dry.
