Frequently Asked Questions

Everything you need to know about our products and services.

Lab-grown diamonds are real diamonds that are made in controlled laboratory environments rather than mined from the earth. Scientists use advanced technology to recreate the conditions under which natural diamonds form, resulting in stones that are identical to mined diamonds in terms of composition, strength, and brilliance. The two primary techniques used are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Because they are produced without mining, lab-grown diamonds are considered a more ethical and environmentally responsible choice, reducing both environmental damage and social concerns linked to traditional diamond extraction.
