LAB GROWN DIAMONDS

All about lab grown diamonds and rings.

LAB GROWN DIAMOND BENEFITS: WHY?

01.

VALUE

Lab grown diamonds offer a cost-effective alternative to natural diamonds. Prices typically range from 70% to 85% lower than mined diamonds due to the shorter supply chain and reduced labor costs.

02.

EXCEPTIONAL QUALITY & BEAUTY

Lab grown or man made diamonds are chemically identical to mined counterparts. Same beautiful visual, robust physical, and chemical traits. Known as hardest substance to man.

03.

CONFLICT-FREE

Both natural and lab diamonds require carbon, intense heat, and high pressure to grow. Mined diamonds develop within the Earth, whereas lab-grown diamonds are produced using state-of-the-art equipment mimicking the Earth's mantle. Hence, mining deposits are not required.

What is a Lab Created Diamond?

When someone purchases a diamond, the consumer should be knowledgable whether their diamond is natural or lab grown. Many might think that lab created diamonds are not real, but that is false. Lab grown, lab created, or man made diamonds are the hardest substance known to man (with mined diamonds). These kind of diamonds have the same visual, physical, and chemical features to their natural counterparts. Like natural diamonds, lab created diamonds also require carbon, intense heat, and high pressure to grow.

DIAMOND CERTIFICATION

GIA

Gemological Institute of America


The Gemological Institute of America is a nonprofit institute that has an international authority on diamonds, gemstones, and pearls. GIA was founded in 1931, and in the 1940s, established the “4Cs” (Cut, Color, Clarity, and Carat Weight) or the “International Diamond Grading System.” The GIA is arguably the leading source of knowledge for all gemstones and jewelry, which is why all Stienhardt Lab Grown Diamonds are graded by GIA.

AWDC

Antwerp World Diamond Center


Antwerp World Diamond Center is recognized as one of the leaders in the diamond industry. For more than five centuries, Antwerp in the country of Belgium has been the capital for international diamond trade. They stand for transparency, integrity, quality, and sustainability. Their main mission is to inspire the current generations and future generations to keep Antwerp at the forefront of the diamond trade industry.

Like GIA, AGS is also a nonprofit organization. AGS stands out amongst other diamond grading systems because they use a 0 to 10 scale, with 0 as the best and 10 as the worst.

IGI

International Gemological Institute

The International Gemological Institute is the world’s largest independent gemstone grading organization. Established in 1975, IGI now has offices all over the globe, with 18 lab locations. This independent laboratory carefully studies colored stones and jewelry, along with lab grown diamonds , to determine authenticity. Other than grading, they also have 14 schools of gemology.

GSI

Gemological Science International

Gemological Science International researchers use technology and software to automate diamond grading. GSI reports represent innovation, integrity, and professionalism. GSI labs globally follow an alphabetical grading system.

GCAL

Gem Certification and Assurance Lab

GCAL was founded in 2001 and is headquartered in New York City, USA. GCAL provides diamond grading reports that detail the quality characteristics of diamonds, including the 4Cs (Cut, Color, Clarity, and Carat Weight), as well as additional information such as fluorescence and light performance.

FAQs

The best gem laboratory for certification and grading is widely recognized as the Gemological Institute of America (GIA). Known for their strict grading standards and comprehensive reports, GIA is highly trusted and respected globally. Their certifications are considered the gold standard in the gem industry, ensuring that diamonds and gemstones are accurately and reliably assessed.
