Moissanite & Lab-Grown Diamonds FAQ:
Everything You Need to Know

Looking for a stunning, sustainable, and affordable alternative to mined diamonds?
Discover why Moissanite and Lab-Grown Diamonds are the modern choice for brilliance, beauty, and ethical luxury.
Below, we answer the most common questions to help you choose your perfect piece of fine jewelry.

Does Moissanite Pass as a Diamond on a Diamond Tester?

Yes. Authentic Moissanite gemstones often register as diamonds on standard diamond testers because of their exceptional hardness rating of 9.25 on the Mohs Scale (diamonds are 10).
Traditional testers rely on thermal conductivity, and Moissanite’s superior durability allows it to pass. However, advanced gem testers can distinguish between the two.

Will Moissanite Become Cloudy Over Time?

No — Moissanite never gets cloudy. Known as a “forever stone,” it maintains its clarity and fire for life. With simple care and occasional cleaning, your Moissanite will sparkle as brilliantly as the day it was set.

What Are Lab-Grown Diamonds?

Lab-grown diamonds are real diamonds, created in high-tech, controlled environments that replicate the natural growth process. They share the same chemical, optical, and physical properties as mined diamonds but are more ethical, sustainable, and affordable.

Are Lab-Grown Diamonds Durable?

Yes. With a perfect 10 on the Mohs hardness scale, lab-grown diamonds are just as durable and brilliant as mined diamonds — ideal for engagement rings and everyday fine jewelry.

Are Lab-Grown Diamonds Certified?

Absolutely. All our Lab-Grown Diamonds come with trusted certifications from IGI (International Gemological Institute) or GIA (Gemological Institute of America), guaranteeing authenticity, quality, and transparency.

Why Are Moissanite and Lab-Grown Diamonds Eco-Friendly?

Both are eco-conscious alternatives to traditional mining.

• Lab-grown diamonds require significantly fewer resources and reduce carbon footprint.

• Moissanite is entirely lab-created, avoiding the environmental and social issues linked to mining.
  Choosing these stones supports sustainable fine jewelry and ethical craftsmanship.

Can You Tell the Difference Between Diamonds and Moissanite?

To the untrained eye, no. Moissanite is visually indistinguishable from a diamond and even has a higher refractive index, giving it more sparkle. Only specialized gemological tools can tell them apart.

How Long Does It Take to Create a Bespoke Ring?

Our custom-designed rings typically take around 14 working days, ensuring every piece meets RIVA’s standard of excellence in design, setting, and finish.

What Materials Do You Use for Jewelry?

We craft our pieces using only the finest metals 9K to 22K Gold and 925 sterling silver each meticulously polished to perfection for lasting brilliance and strength.

Is Moissanite a Good Choice for Engagement Rings?

Absolutely. Moissanite engagement rings offer unmatched sparkle, durability, and value. Their ethical origin and radiant brilliance make them the modern symbol of love and responsibility.

Are Lab-Grown Diamonds Cheaper Than Natural Diamonds?

Yes typically 20–40% more affordable than mined diamonds of equivalent size and grade. This lets you invest in a larger or higher-quality stone while staying within budget.

How Do I Care for Moissanite and Lab-Grown Diamond Jewelry?

Both are easy to maintain. Clean regularly with warm water, mild soap, and a soft brush.
Avoid harsh chemicals and store your jewelry in a protective pouch or box to keep it shining like new.

Why Choose Moissanite or Lab-Grown Diamonds?
