Why choose a lab-grown diamond engagement ring?
A marriage proposal is a once-in-a-lifetime moment. Today, more and more couples are choosing a modern, ethical, and brilliant alternative: the lab-grown diamond. Combining the prestige of a 14k or 18k yellow gold engagement ring with the brilliance of a sustainable gemstone has become the hallmark of responsible elegance.
What is the price of a 1-carat lab-grown diamond?
This is often the central question when planning a jewelry project. The price of a 1-carat lab-grown diamond is one of its greatest advantages. For the same quality (cut, color, and clarity), a cultured diamond costs approximately 60% to 80% less than a mined diamond.
 
 
Affordability: While a 1-carat natural diamond can represent a colossal investment, the lab-grown version allows you to afford a high-quality stone within a controlled budget.
 
 
Certified Quality: Just like natural stones, our lab-grown diamonds are certified by international organizations (IGI or GIA), guaranteeing their authenticity and value.

Timeless Elegance: 14k or 18k Yellow Gold Engagement Rings
Choosing the setting is just as crucial as selecting the stone. Yellow gold remains the top favorite for its warm glow and eternal symbolism.
14-Karat or 18-Karat Gold: Which one to choose?
The choice between a 14k or 18k yellow gold engagement ring depends on your priorities:
 
 
18-Karat Gold (750/1000): This is the standard of French high jewelry. Richer in pure gold, it offers a prestigious luster and excellent durability over time.
 
 
14-Karat Gold (585/1000): More scratch-resistant due to its composition, it is ideal for tighter budgets while maintaining the perfect aesthetic of yellow gold.
