Lab-grown diamonds have gained significant popularity in recent years, but a common question remains: Are lab-grown diamonds considered real? The short answer is yes—lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. However, their origin and market perception create key distinctions that buyers should consider.
This expert analysis breaks down what makes a diamond “real,” how lab-grown diamonds compare to natural diamonds, and what factors influence their value and acceptance in the jewelry industry.
A diamond, whether natural or lab-grown, is defined by its composition, structure, and physical properties.
To be classified as a real diamond, a gemstone must be composed of pure carbon arranged in a crystalline structure known as a diamond cubic lattice. Both natural and lab-grown diamonds meet this criterion.
Lab-grown diamonds, also called synthetic or cultured diamonds, are created in laboratories using advanced technology that replicates the natural diamond formation process. The two primary methods are:
Natural diamonds form over billions of years under high pressure and temperature deep within the Earth. They are then mined, cut, and polished before reaching the consumer market.
Despite being chemically identical, lab-grown diamonds face skepticism due to:
Reputable gemological laboratories such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) certify lab-grown diamonds, just like natural diamonds.
Each certified lab-grown diamond comes with a grading report assessing:
However, the certificate clearly states that the diamond is lab-grown, ensuring transparency in the marketplace.
Yes, the jewelry industry widely recognizes lab-grown diamonds as real diamonds. Major retailers such as Tiffany & Co., Blue Nile, and Brilliant Earth now offer lab-grown diamond collections.
However, some luxury jewelers and auction houses still focus exclusively on natural diamonds due to their rarity and long-term value.
✅ Identical to natural diamonds in appearance and durability.
✅ More affordable—typically 50%–70% cheaper than natural diamonds.
✅ Ethically sourced—no mining involved, reducing environmental impact.
✅ Wider selection—flawless or near-flawless options are more accessible.
❌ Lower resale value—lab-grown diamonds depreciate significantly.
❌ Not as rare—unlike natural diamonds, lab diamonds can be mass-produced.
❌ Perceived as "less prestigious" by some buyers and traditionalists.
Lab-grown diamonds are an excellent choice if:
However, if you’re looking for a long-term investment piece, a natural diamond may be a better option due to its historical appreciation and strong resale market.
Yes, lab-grown diamonds are 100% real diamonds. They have the same chemical composition, hardness, and brilliance as natural diamonds. The only difference is their origin—one is created in a lab, while the other is formed naturally over billions of years.
While lab-grown diamonds offer affordability and ethical benefits, they do not hold the same resale value or rarity as natural diamonds. Ultimately, the choice comes down to personal preference, budget, and priorities—whether you value rarity and tradition or modern innovation and cost savings.
