Frequently Asked Questions
Is diamond durable enough for everyday wear?
Yes. Diamond rates 10 on the Mohs hardness scale, making this piece durable enough for daily wear.
How much does this diamond ring cost in solid gold?
At The Karat Store, this diamond ring starts at $2,106 in 10K gold, $2,376 in 14K gold, and $2,700 in 18K gold — all solid gold, not plated.
Should I choose 10K, 14K, or 18K gold for this piece?
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 solid gold all the way through, or just gold-plated?
This piece is solid gold throughout, not gold-plated — the karat purity runs all the way through the metal. 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.
Can this ring be resized?
