Frequently Asked Questions (FAQ)
- What are lab-grown diamonds?
- Lab-grown diamonds are real diamonds created in controlled laboratory environments using advanced HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) technology.
- Are lab-grown diamonds real diamonds?
- Yes. Lab-grown diamonds possess the exact same optical, physical, and chemical properties as mined diamonds, consisting of pure carbon crystallized in an isometric cubic system.
- What is the difference between lab-grown and natural diamonds?
- The primary difference is origin. Natural diamonds crystallize deep in the Earth's mantle over billions of years, whereas lab-grown diamonds are cultivated in specialized laboratories using advanced engineering in weeks.
- What is HPHT diamond growth?
- HPHT (High Pressure High Temperature) replicates the natural earth conditions under which diamonds form, subjecting a diamond seed to extreme pressures (approx. 55,000–60,000 atmospheres) and temperatures exceeding 1,300°C–1,600°C.
- What is CVD diamond growth?
- CVD (Chemical Vapor Deposition) grows diamonds layer by layer from carbon-rich gases (such as methane) inside a vacuum chamber at moderate temperatures and low pressure.
- Are your diamonds certified?
- Yes. Diamonds are supplied with internationally recognized certifications from IGI (International Gemological Institute), GIA (Gemological Institute of America), or HRD Antwerp, complete with laser girdle inscriptions.
