Frequently Asked Questions
Is a tennis diamond necklace a good gift?
Yes. Diamond necklaces are a popular gift for birthdays, anniversaries, and holidays — a meaningful step up from costume jewelry, and diamond set in solid gold holds its value and appearance far longer than plated pieces.
What's the price range for this tennis diamond necklace across different gold karats?
At The Karat Store, this tennis diamond necklace starts at $28,314 in 10K gold, $31,944 in 14K gold, and $36,300 in 18K gold — all solid gold, not plated.
Should I choose 10K, 14K, or 18K gold for this necklace?
18K gold (75% pure) has the richest color and softest feel. 14K gold (58.3% pure) is the most popular balance of durability and value. 10K gold (41.7% pure) is the most affordable and most scratch-resistant.
Is this necklace solid gold all the way through, or just 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.
What occasions is this necklace best suited for?
This necklace works for both everyday wear and special occasions — the solid gold setting and diamond stone dress up simple outfits while still being subtle enough for daily use.
What's the best way to keep this diamond necklace looking new?
Soak briefly in warm water with a drop of mild dish soap, gently brush with a soft-bristled brush, rinse, and pat dry. Avoid chlorine, harsh chemicals, and ultrasonic cleaners, and remove before swimming, showering, or exercising.
