LAB-GROWN DIAMOND ENGAGEMENT RING FAQS

A lab-grown diamond is a diamond created in a controlled environment using advanced technology that replicates the natural growth process. It is composed of crystallized carbon in the same cubic structure as a natural diamond and has the same chemical, physical, and optical properties.

Yes. Lab-grown diamonds are real diamonds, not simulants. They have the same chemical, physical, and optical properties as natural diamonds, displaying the same brilliance, fire, and hardness. While the two are visually indistinguishable, at LUMI Jewelry they are identified and verified using professional gemological equipment, ensuring accurate grading and full transparency.

Natural diamonds formed deep within the Earth billions of years ago, while lab-grown diamonds are created in a laboratory. Both are made of pure crystallized carbon and share the same structure and appearance; the difference is their origin and the way they are formed.

The price of a lab-grown diamond engagement ring depends on the selected diamond, including its cut, colour, clarity, and carat weight, as well as the setting design and metal. At LUMI Jewelry, we offer a range of options and guide you through the selection process to create a ring that aligns with your vision and preferred budget.

Yes. At LUMI Jewelry, each lab-grown diamond can be set into a fully custom design. The process begins with a complimentary private consultation, includes a CAD preview for approval, and is typically completed within 2–3 weeks.

Most of our lab-grown diamonds are accompanied by grading reports from leading laboratories, most commonly GIA and IGI, and each ring includes an appraisal prepared by a CJA-certified appraiser.

No. Lab-grown and natural diamonds are visually identical. Both produce the same light performance and are graded using the same standards for cut, colour, clarity, and carat weight.

Our lab-grown engagement rings are crafted in 14K and 18K white, yellow, and rose gold, as well as platinum, allowing each ring to be tailored to your preferred style.
