Frequently Asked Questions
Is a heart 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.

Is this necklace solid gold all the way through, or just gold-plated?
