Frequently Asked Questions
Is a 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.
How much does this diamond necklace cost in solid gold?
Pricing on this diamond necklace runs from $1,240.20 (10K) to $1,399.20 (14K) to $1,590 (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.
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.
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.
