Frequently Asked Questions
Can this necklace be layered with other necklaces?
Yes. This piece works well as part of a layered look — pair it with a slightly shorter or longer chain in a different style for contrast, or wear it alone for a cleaner, minimalist look.
How much does this tennis tourmaline necklace cost in solid gold?
Pricing on this tennis tourmaline necklace runs from $6,981 (10K) to $7,876 (14K) to $8,950 (18K) at The Karat Store, with every option solid gold throughout.
Should I choose 10K, 14K, or 18K gold for this necklace?
18K gold gives the deepest color, 14K gold is the everyday favorite for its balance of strength and value, and 10K gold is the toughest and most budget-friendly.
How can I tell this is real solid gold and not gold-plated?
This necklace is solid gold throughout, not gold-plated — the karat purity runs all the way through the metal, not just a surface layer. Unlike plated jewelry, it won't flake, discolor, or expose base metal over time, and it carries a karat hallmark stamp as proof of authenticity.
Is a tennis tourmaline necklace a good gift?
Yes. Tourmaline necklaces are a popular gift for birthdays, anniversaries, and holidays — a meaningful step up from costume jewelry, and tourmaline set in solid gold holds its value and appearance far longer than plated pieces.
How do I clean and care for this necklace at home?
Clean every few weeks with warm water, a mild soap, and a soft brush, then dry thoroughly. Take it off before applying perfume or lotion, and store it flat in its own pouch to prevent tangling and scratches.
