Frequently Asked Questions about Custom Moissanite Rings

Have questions before you create your own moissanite ring? We have answers. If you don’t see your question below, check out our FAQs page for more.

How does moissanite compare to diamonds?

Moissanite is not the same as a diamond, but it offers a similar sparkle, brilliance, and durability at a lower price. Since moissanite is lab-grown, it’s also an ethical, eco-friendly choice for those who value sustainability without sacrificing beauty.

How do I choose the right ring size?

You can find your ring size by using an online sizing chart, measuring the diameter of a well-fitting ring, or visiting a jeweler for professional sizing. We also recommend using a plastic ring sizer, available on Amazon for around $4 with free shipping.

What types of moissanite wedding bands do you offer?

We offer a variety of moissanite wedding bands, including classic styles like eternity bands as well as contemporary designs featuring Pave or Solitaire stones.

What's better, lab diamond or moissanite?

It depends on what you’re looking for, as both lab diamonds and moissanite are remarkable in their own ways. A lab grown diamond closely mimics a natural diamond in look and composition. However, when you build your own moissanite ring, it delivers vibrant fire, durability, and a more affordable alternative.

How long will a moissanite ring last?

A custom moissanite ring can last a lifetime with proper care. Moissanite is nearly as hard as a diamond, making it highly resistant to scratches and everyday wear.

Is it worth buying a moissanite ring?

Yes, moissanite rings are worth buying if you want stunning sparkle, durability, and an ethical, budget-friendly alternative to diamonds. When you create your own moissanite engagement ring, you’re getting a piece with exceptional brilliance that can last a lifetime with proper care.
