Moissanite Loose Stones – FAQ
Thinking about purchasing a moissanite loose stone? We’ve gathered the most frequently asked questions to help you make an informed decision. From choosing the right cut and carat size to setting and care tips, find everything you need to know about these brilliant, ethical, and timeless gemstones.
How does moissanite compare to a diamond in terms of brilliance?
Moissanite has a higher refractive index (2.65) than diamonds (2.42), meaning it reflects more light and has a stronger fire and sparkle. It’s one of the most brilliant gemstones available.
What shapes and cuts are available for moissanite loose stones?
We offer a variety of cuts, including:
✔ Round Brilliant – Maximum fire and sparkle
✔ Oval & Cushion – Soft elegance with a modern touch
✔ Emerald & Asscher – Step-cut for a sleek, sophisticated look
✔ Princess & Radiant – Sharp brilliance with a contemporary edge
✔ Pear & Marquise – Elongated, unique, and eye-catching
Will moissanite change colour or get cloudy over time?
No! Moissanite is a permanent gemstone that will not fade, discolour, or become cloudy. It maintains its clarity and brilliance for a lifetime.
Can moissanite be used in engagement rings or fine jewellery?
Absolutely! Moissanite is one of the hardest gemstones (9.25 Mohs scale), making it durable for daily wear in engagement rings, earrings, and fine jewellery.
What carat sizes are available for moissanite loose stones?
We offer moissanite stones in a wide range of carat sizes, from 0.5ct to 10ct and beyond, allowing you to create anything from subtle elegance to bold statement pieces.
How do I clean and care for my moissanite stone?
To keep your moissanite sparkling:
- Use warm water, mild soap, and a soft brush to clean it.
- Avoid harsh chemicals or abrasive cleaners.
- Store it in a jewellery box to prevent scratches.
Can moissanite be set in any type of jewellery?
Yes! Moissanite can be set in rings, earrings, pendants, bracelets, and custom jewellery. It works beautifully in 18K gold, platinum, and other high-end metals.
Is moissanite an ethical and sustainable choice?
Yes! Moissanite is 100% lab-created, meaning it is conflict-free and environmentally friendly, unlike mined gemstones. It’s the perfect ethical luxury alternative.
How do I choose the right moissanite size for my setting?
If replacing a diamond, use a size-to-carat conversion chart since moissanite is slightly lighter than diamonds. Our team can help you select the perfect stone based on your jewellery design.
Does moissanite come with a certification?
Yes! Our moissanite loose stones come with authenticity certification, ensuring their quality, cut, and brilliance meet the highest industry standards.
