FAQS

Yes, all our diamonds are 100% real and natural. We source authentic natural diamonds that meet strict quality standards. Each diamond is genuine and comes with proper certification to verify its authenticity.

Yes, all our diamond jewelry comes with our Kef Diamonds brand certification and certification from recognized international gemological laboratories such as GIA (Gemological Institute of America), IGI (International Gemological Institute), or other reputable labs. These certificates provide detailed information about the diamond's characteristics including cut, clarity, color, and carat weight, ensuring complete transparency and authenticity.

Yes, we offer a free lifetime warranty against any manufacturing defects. Our lifetime warranty does not include any damage done to the piece due to everyday wear or external force. If KEF jewelry pieces have been worked on by another jeweler, then the warranty will be voided.

While lab-grown diamonds are created in controlled laboratory environments and have the same physical properties as natural diamonds, we primarily work with natural diamonds. Natural diamonds are formed deep within the Earth over billions of years, making each one truly unique. We believe in the timeless value and authenticity of natural diamonds. Additionally, lab-grown diamonds have minimal to no resale value compared to natural diamonds, which retain their value as a long-term investment and heirloom.

We use 18KT gold for our jewelry because it offers the perfect balance of purity, durability, and beauty. 18KT gold contains 75% pure gold mixed with 25% alloy metals, making it strong enough for everyday wear while maintaining a rich gold color. 21KT gold, while containing more pure gold (87.5%), is softer and more prone to scratches and damage, making it less suitable for fine jewelry that's meant to last a lifetime.

The difference lies in the alloy metals mixed with pure gold. Yellow Gold is mixed with silver and copper to maintain its natural golden color. White Gold is alloyed with white metals like palladium or nickel and is often rhodium-plated for a bright white finish. Rose Gold gets its romantic pink hue from a higher copper content in the alloy. All three are equally durable when made in 18KT.

No, Rose Gold, White Gold, and Yellow Gold have the same intrinsic value when they are the same karat weight (e.g., all 18KT). The price difference, if any, comes from the manufacturing process - White Gold may cost slightly more due to the rhodium plating process, but the gold content and value remain the same across all three colors.

The most accurate way is to visit a jeweler for professional sizing. Alternatively, you can use a ring sizer tool at home or measure an existing ring that fits well. Ring sizes can vary slightly between fingers and throughout the day, so we recommend measuring at different times for the best fit.
