Frequently Asked Questions
Is amethyst durable enough for everyday wear?
Yes. Diamond rates 10 on the Mohs hardness scale, the hardest of any gemstone, so this piece holds up well to everyday wear.
How much does this amethyst ring cost in solid gold?
At The Karat Store, this amethyst ring starts at $3,576.3 in 10K gold, $4,034.8 in 14K gold, and $4,585 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?
Yes. Select your ring size from the dropdown before checkout. If you're unsure of your size, we recommend visiting a local jeweler for an accurate measurement.
How do I clean and care for this piece at home?
Clean gently with warm water, a mild soap, and a soft brush, then dry thoroughly. Avoid chlorine, harsh chemicals, and ultrasonic cleaners, and store it separately from other jewelry to prevent scratching.
