Cobalt Black 7mm Polished Comfort Fit Ring

We provide lab-grown diamonds, which have the exact same physical and chemical properties as natural diamonds, but are more eco-friendly and cost-effective.

Yes, all of our lab-grown diamonds come with certification from reputable gemological institutes, ensuring authenticity and quality.

Our rings are crafted with high-quality materials and treated with an anti-oxidation finish. Under normal wear, they will not fade. We recommend avoiding long-term contact with chemicals (perfume, cleaning products) to maintain the shine.

Yes, you can use a ring you already own to find your ring size. You can measure the inside of the ring and find the corresponding size for the measurement on our ring size print out.

Planning a surprise romantic and creative proposal？ You can find out your partner’s ring size without them knowing. The easiest option is to simply ask their friends or family. If you’d like to measure your partner’s ring size secretly, we suggest measuring a ring they already wear.

Definitely! Lab-grown diamonds are identical to mined diamonds in beauty and durability, but they are more affordable and eco-friendly.

Absolutely! You can choose the diamond shape, size, setting, and metal type. Our designers will help you create a unique piece.
