THE PROCESS
CREATING LAB DIAMONDS
Lab grown diamonds are created using advanced technology that replicates the natural diamond-forming process. Two main methods—High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD)—produce real diamonds with the same physical, chemical, and optical properties as mined stones. These sustainable diamonds are grown in controlled environments, allowing for consistent quality and significantly less environmental impact.
At James Porter & Son, we proudly offer lab grown diamond rings and jewellery that combine innovation with ethical elegance. Discover the future of fine jewellery with beautiful, responsibly made diamonds grown above ground, not mined from it.
GRADING
LAB GROWN DIAMONDS
Like natural diamonds, lab grown diamonds are graded using the 4Cs: Cut, Colour, Clarity, and Carat weight. Each diamond is carefully assessed by expert gemologists to determine its quality and brilliance. The cut defines sparkle, colour measures hue, clarity checks for imperfections, and carat indicates size. At James Porter & Son, we ensure that every lab grown diamond meets our strict standards for beauty and precision.
Whether you're choosing an engagement ring or a statement piece, our ethically created diamonds offer the same sparkle and grading excellence as their mined counterparts—without the environmental or ethical concerns.
Certification
for lab grown diamonds
All our lab grown diamonds come with independent certification from trusted gemological laboratories such as IGI or GIA. These certificates verify the diamond’s authenticity, grading, and whether it was grown using HPHT or CVD methods. Certification ensures transparency, helping you buy with confidence and peace of mind. Each document includes detailed information about the diamond's 4Cs and origin, just as with natural diamonds. By choosing certified lab grown diamond jewellery, you’re investing in verified quality and ethical craftsmanship backed by generations of trust and excellence at our Glasgow boutique.
