Lab Grown Diamond Jewelry — Handcrafted with Certified Brilliance
Lab grown diamonds are chemically, physically, and optically identical to mined diamonds — at a fraction of the cost. At Riolls Jewels, every lab grown diamond is IGI-certified and set by hand into custom designs by our master goldsmiths in Surat, India.
What are lab grown diamonds?
Lab grown diamonds — also known as lab created diamonds, cultured diamonds, or man-made diamonds — are real diamonds produced in a controlled laboratory setting using advanced technology that replicates the natural diamond formation process. They are created using one of two methods: CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature).
The result is a genuine diamond that is chemically, physically, and optically identical to a mined diamond. Lab grown diamonds have the same carbon crystal structure, the same hardness (10 on the Mohs scale), and the same optical properties — including the characteristic brilliance, fire, and scintillation that make diamonds the world's most coveted gemstone.
At Riolls Jewels, all lab grown diamonds are independently certified by IGI (International Gemological Institute) and graded for the same 4Cs — cut, color, clarity, and carat weight — as natural diamonds. Every stone comes with a full certification report.

The case for lab grown diamond jewelry
The lab grown diamond market has grown exponentially as consumers — particularly millennials and Gen Z — increasingly prioritize ethical sourcing, environmental sustainability, and value transparency when making luxury purchases. Lab grown diamonds offer all three without any compromise on beauty, durability, or prestige.
For engagement ring buyers, the value proposition is compelling: a lab grown diamond of identical quality (same cut, color, clarity, and carat weight) costs 50–80% less than a mined equivalent. This means you can either invest the savings elsewhere — into a higher-quality setting, a larger stone, or a matching wedding band — or simply enjoy a more responsible purchase at a lower price point.
At Riolls, we believe the diamond you choose should reflect your values as much as your style. Whether you choose a natural diamond or a lab grown diamond, the craftsmanship remains the same: 100% handmade by a single master goldsmith at our Surat atelier, with full certification, hallmarking, and a lifetime of brilliance.
Lab grown diamond jewelry — frequently asked questions
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds — they are chemically, physically, and optically identical to mined diamonds. They are made of pure carbon crystallized in the same cubic crystal structure. The only difference is their origin: they are grown in a controlled laboratory environment using advanced CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) processes, rather than being extracted from the earth. They score a perfect 10 on the Mohs hardness scale and exhibit the same brilliance, fire, and scintillation as natural diamonds. At Riolls, all lab grown diamonds are independently certified by IGI (International Gemological Institute).
What is the difference between lab grown and natural diamonds?
The only meaningful difference between lab grown and natural diamonds is their origin and price. Natural diamonds are formed deep within the earth over billions of years under extreme heat and pressure. Lab grown diamonds are created in weeks using technology that replicates those conditions. In terms of physical properties — hardness, brilliance, fire, refractive index, and crystal structure — they are identical. Even trained gemologists cannot distinguish between them without specialized equipment. Lab grown diamonds typically cost 50–80% less than comparable natural diamonds, making them an excellent choice for buyers who want a larger, higher-quality stone within a given budget.
Are lab grown diamonds ethical and sustainable?
Lab grown diamonds are widely considered a more ethical and sustainable alternative to mined diamonds. They do not require large-scale mining operations, which can cause significant environmental disruption including land degradation, water pollution, and habitat destruction. They are inherently conflict-free, eliminating the risk of financing armed conflict. The carbon footprint of lab grown diamonds is lower than that of mined diamonds, though it is not zero — the CVD and HPHT growth processes require significant energy. At Riolls, we pair lab grown diamonds with ethically sourced gold and fully transparent manufacturing to deliver genuinely responsible luxury jewelry.
Does Riolls offer both lab grown and natural diamonds?
Yes. Riolls Jewels offers both natural (mined) diamonds and lab grown diamonds for all custom designs, including engagement rings, wedding bands, and bespoke commissions. Natural diamonds are available with GIA (Gemological Institute of America), IGI, or SGL certification. Lab grown diamonds are certified by IGI. During your free private consultation, our gemologists will help you understand the differences and choose the option that best fits your values, aesthetic preferences, and budget.
How much cheaper are lab grown diamonds compared to natural diamonds?
Lab grown diamonds typically cost 50–80% less than comparable natural diamonds of the same carat weight, cut, color, and clarity. For example, a 1-carat, excellent-cut, VS1 clarity, F color natural diamond might cost $5,000–$7,000, while an identical lab grown diamond might cost $1,000–$2,000. This price difference allows buyers to choose a significantly larger or higher-quality stone within the same budget. At Riolls, we pass these savings directly to you — our custom lab grown diamond rings start at a fraction of comparable high-street prices because we craft directly from our Surat atelier with no retail middlemen.
