2. Does moissanite exhibit a rainbow effect?

Yes, moissanite is known for its distinct 'rainbow effect,' which is more pronounced than in diamonds. This is due to its higher refractive index, causing it to disperse light into vibrant spectral colors. Diamondrensu has now gained the expertise to cut the moissanite so that it reflects least rainbow lights.

4. Are lab-grown diamonds identical to natural diamonds?

Yes, lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. The primary difference lies in their origin, as lab-grown diamonds are created in controlled environments.

5. Can I wear a lab-grown diamond as an alternative to my birthstone, which is a natural diamond?

Absolutely. Lab-grown diamonds make a suitable alternative to natural diamonds for birthstone purposes. They offer the same aesthetic and physical properties, making them an excellent choice for those who prefer a more environmentally and ethically sourced option.

Can't Break Easily

Both lab-grown diamonds and moissanite are known for their durability and resistance to chipping and breaking, thanks to their hardness. Lab-grown diamonds score a perfect 10/10, while moissanite ranges between 9.25-9.50 on the Mohs hardness scale. Although highly resilient, if struck with extreme force against a hard surface, they might chip. However, due to their "indistinct" cleavage, neither moissanite nor lab-grown diamonds break along crystal lines.

Frequently Asked Questions

The weight disparity between moissanite and diamonds stems from their differing densities. Moissanite, composed of silicon carbide, has a lower density compared to diamonds, which are made of carbon. As a result, for the same size or diameter, a moissanite stone will weigh less than its diamond counterpart. This difference in density is crucial for jewelers and consumers to consider, especially when comparing stones based on carat weight, a common measure for gemstones.

The choice between moissanite and lab-grown diamonds depends on personal preferences and priorities. Moissanite is more affordable and has a greater brilliance and fire, whereas lab-grown diamonds are identical in composition to natural diamonds and are valued for their classic appeal and has excellent brilliance and luster same as natural diamond.
