I had never bought a diamond before, so the thought of choosing the perfect engagement ring felt overwhelming—until I found Mimi. From the very first consultation, the team guided me through every step, explaining diamond quality, settings, and styles with incredible patience and expertise.

What truly set them apart was the option to create a dupe ring in silver with Cubic Zirconia, allowing my fiancée to see and try it before we ordered the final piece in 18K gold with a stunning diamond. This gave us both confidence that it was exactly what she wanted.

When the real ring arrived, she was absolutely in love—and so was I. The entire process was seamless, personalized, and stress-free. Milena didn’t just "sell" me a ring; they made sure I understood and felt confident in my choice. I couldn’t be happier! Thank you so much.

Frequently Asked Questions

Absolutely! Lab-grown diamonds are identical to mined diamonds, boasting the same chemical composition, crystal structure, and physical properties as their natural counterparts. The primary difference lies in their origin and the age of the carbon atoms. Only through using advanced technology, we can determine whether a diamond is from a lab or mined from the Earth.

Yes, they come in all different shapes, color and inclusion grades! Lab-grown diamonds can exhibit inclusions just like natural diamonds. This is a result of the growth process involved in their creation. During production in a controlled laboratory setting, fluctuations in temperature and pressure, impurities in the growth chamber, or interruptions can lead to the formation of inclusions. While inclusions are less common in lab-grown diamonds than in natural ones, they can still occur and vary in type, size, and visibility.

Lab-grown diamonds showcase the same exceptional hardness and durability as natural diamonds, earning a perfect score of 10 on the Mohs scale of mineral hardness. This means they are highly resistant to scratching and wear, making them ideal for everyday jewelry pieces like engagement rings, earrings, and bracelets.

The CVD Method

In the CVD (Chemical Vapor Deposition) process, a tiny diamond seed is placed in a vacuum chamber filled with carbon-rich gases. Once heated to extreme temperatures, the gas transforms into plasma, causing carbon particles to break free. These particles settle on the diamond seed, allowing it to grow into a magnificent gem.

The HPHT Method

The HPHT (High Pressure High Temperature) technique involves placing a diamond seed in carbon—the very material diamonds are made of. Subjected to intense heat and pressure, this method replicates the natural conditions under which diamonds form. As the carbon melts, it envelops the seed, and when it cools, a stunning diamond is born.

Yes! Lab-grown diamonds offer an ethical alternative to traditional diamonds. They don’t inflict the same environmental damage as diamond mining and are free from the ethical concerns such as blood diamonds, labor practices, community displacement and economic exploitations sometimes linked to natural diamonds.

Lab-grown diamonds not only provide an ethical and environmentally friendly choice, but they also offer incredible value for money without sacrificing quality.

The quality of lab-grown diamonds is assessed using the same criteria as natural diamonds—the renowned 4 C’s: Cut, Color, Clarity, and Carat weight.

The globally leading independent certification bodies, that also grade mined diamonds are IGI and GIA. An IGI or GIA report is the universal language of trust in the gemological world, ensuring your diamond's quality and authenticity.

Lab-grown diamonds undergo a careful transformation similar to natural diamonds, ensuring they shine beautifully in every piece of jewelry. The process starts with cutting, where skilled gem cutters shape the rough diamond to enhance its brilliance. Next, the diamond is polished to eliminate imperfections and maximize its shine.
