How To Measure Your Ring Size？

Method One: If You Have An Existing Ring

1. Measure the diameter (mm) of a ring that fits the desired finger

2. Use the Ring Sizing Chart to locate your size

Method Two: If Not, Measure Your Finger

1. Wrap a strip of paper around your finger, just above the knuckle, and mark the point at which the two ends meet

2. Measure the paper from mark to mark to find your ring circumference (mm)

3. Check international ring sizing chart

Note: Please make sure to choose a size when placing an order.

Other Tips:

1. Measure your finger in warm temperatures at the end of the day.

2. If your knuckle is a lot larger than the base of your finger, measure both the base of your finger and your knuckle and select a size between the two.

3. When considering a wide band, move up a size from your measurement, for comfort’s sake

Home Cleaning

Bring it back to the basics. You should complete a weekly home cleaning routine to keep your moissanite jewelry sparkling at its finest. Soak your moissanite jewelry in warm water for 10 minutes with gentle dish soap. Grab a soft toothbrush and gently scrub those hard-to-reach areas (while being cautious around the prongs). Once your jewelry is looking its best, you can rinse it off and leave it to dry.

Jewelry Cleaner Recommendations

Apply the product to the surface of your moissanite stone using a clean cloth and rub gently. You may need to leave it on for a bit and scrub with a soft toothbrush until the build-up is gone (this may require some elbow grease depending on how much is stuck on there).

FAQs

No. Moissanite is known for its bright, clean sparkle that closely resembles a diamond in real life.

Unlike lower-quality stones, our D color moissanite appears clear and elegant, not cloudy or “rainbow-like.” In natural light, most people cannot tell the difference without special tools.

Many customers choose moissanite specifically because it looks luxurious without feeling flashy.

Moissanite and diamonds are both premium gemstones, but they shine in different ways.

Moissanite has more fire (sparkle) than a diamond
It is nearly as hard (9.25 on the Mohs scale vs. diamond’s 10)
Visually, they are extremely similar to the naked eye
Moissanite offers exceptional value, often costing a fraction of the price

It’s a popular choice for modern brides who want beauty, durability, and smart value.

Yes. Moissanite is one of the hardest gemstones available and is highly resistant to scratches and chips.

It’s suitable for daily wear, including engagement rings and wedding bands, and holds up well with normal activities.

With proper care, your ring will maintain its brilliance for years.

Our rings are crafted with high-quality plating designed for long-lasting wear.

Like all plated jewelry, the lifespan depends on wear habits, but with normal use and proper care, the finish remains beautiful.

To extend longevity, we recommend:

Removing the ring before heavy physical activity
Avoiding contact with harsh chemicals
Storing it in a dry place when not worn

No worries at all. We offer a 30-day easy return and exchange policy.

If the size isn’t right, simply contact our support team and we’ll help you exchange it quickly and smoothly.

We also provide a detailed ring size guide to help you choose confidently.

Rodiffy Moissanite Stone

Moissanite, a gem-quality silicon carbide, resembles diamond but is a superior alternative. It offers exceptional fire and brilliance, and its hardness makes it ideal for heirloom-quality jewelry. Our Moissanites are expertly cut and polished to a higher standard than many diamonds found in engagement rings.
