Yes, at Siyagems, we proudly offer a wide range of lab-grown diamond jewelry crafted with both CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) diamonds.

To ensure complete peace of mind, our lab-grown diamonds are accompanied by certifications from trusted gemological institutions such as:

These certifications verify the authenticity, quality, and grading of each diamond, giving you the assurance that you're investing in jewelry that meets the highest industry standards — ethically and beautifully.

At Siyagems, quality is our promise. Every piece of jewelry is made using solid precious metals — whether it’s Sterling Silver, 10k, 14k, 18k Gold, or Platinum. We do not use plating, ensuring your jewelry maintains its beauty and integrity for years to come.

Each item is stamped with a purity hallmark on the inside, giving you confidence that you're receiving authentic, high-quality craftsmanship.

This commitment to using real, enduring materials means you’re investing in jewelry that not only looks beautiful but also stands the test of time.

Lab-grown diamonds — also known as lab-created, eco-friendly, solar, or conflict-free diamonds — are real diamonds created in a highly controlled laboratory environment. These diamonds are formed from a tiny carbon seed or crystal and developed under conditions that replicate the natural diamond-growing process found deep within the Earth’s crust.

This modern method allows us to produce 100% ethical and sustainable diamonds, free from the environmental damage and ethical concerns often associated with traditional mining, such as human rights violations and child labor.

At Siyagems, our lab-grown diamonds are proudly crafted in our certified manufacturing unit, ensuring responsible sourcing, exceptional quality, and complete transparency — without compromise.

Lab-grown diamonds — whether produced through CVD (Chemical Vapor Deposition) or HPHT (High Pressure High Temperature) methods — have the same chemical composition and physical properties as natural diamonds. They are real diamonds in every sense.

However, it's important to be aware of testing nuances:

-> HPHT Diamonds: In some cases, HPHT diamonds may give false readings as moissanite when tested using certain older or less advanced diamond testers. This is due to the limitations of the technology used in basic thermal or electrical conductivity testers.
-> CVD Diamonds: Typically, CVD diamonds will test accurately as diamonds using most standard thermal diamond testers, thanks to their consistent thermal conductivity profile.

For definitive identification, we recommend relying on certified gemological laboratories such as:

-> IGI (International Gemological Institute)
-> GIA (Gemological Institute of America)

These labs use advanced methods to correctly distinguish between natural, CVD, and HPHT diamonds, and provide detailed certificates that verify authenticity, quality, and origin.

At Siyagems, we ensure all our lab-grown diamonds are professionally graded and certified, giving you clarity and confidence in every purchase.

Absolutely — lab-grown diamonds are 100% real diamonds.

They share the exact same physical, chemical, and optical properties as natural diamonds, including the brilliance, fire, and sparkle that make diamonds so desirable. The only difference lies in their origin: lab-grown diamonds are created in a controlled laboratory environment using advanced technology that replicates the natural diamond-forming process.

To the naked eye, it’s nearly impossible to distinguish a lab-grown diamond from a mined one.

Only specialized gemological laboratories like GIA (Gemological Institute of America), IGI (International Gemological Institute), and EGL (European Gemological Laboratory) have the equipment and expertise to accurately identify the difference.

At Siyagems, we proudly offer certified lab-grown diamonds — delivering beauty, value, and ethical peace of mind.

At Siyagems, every lab-grown diamond we offer is certified by internationally recognized gemological institutions such as the:

-> GIA (Gemological Institute of America)
-> IGI (International Gemological Institute)

These certifications verify the authenticity, quality, and grading of each diamond, ensuring complete trust and transparency in your purchase. When you shop with us, you can be confident you're receiving a genuine, high-quality lab-grown diamond — backed by the most respected names in the industry.

At Siyagems, we proudly offer a wide selection of moissanite gemstones and moissanite jewelry, crafted to deliver exceptional brilliance and timeless beauty.
