Frequently asked questions
Which metal should I choose?
All three karats are solid rose gold, so it comes down to your priorities. Choose 10K for the most durable, budget-friendly option, 14K for the classic balance of durability and rich color (our most popular pick), or 18K for the highest gold content and warmest hue. Our karat comparison guide walks through the trade-offs.
Is this real solid gold?
Yes. This ring is crafted from genuine solid gold in your chosen karat — never plated or filled — so its color is permanent and it will not fade or turn your skin green.
