Frequently Asked Questions
What chain length should I choose for this necklace?
Chain length is a matter of preference and where you want the pendant to sit: 16" sits at the collarbone, 18" is the most versatile everyday length, and 20"+ sits lower for a more dramatic look. Check the size options on this page for what's available.
What's the price range for this solitaire diamond necklace across different gold karats?
At The Karat Store, this solitaire diamond necklace starts at $2,496 in 10K gold, $2,816 in 14K gold, and $3,200 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.
Is this necklace durable enough for everyday wear?
Yes. Diamond rates 10 on the Mohs hardness scale, and set in solid gold, this necklace holds up well to daily wear.
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.
