• The creation process typically takes 6-10 weeks from start to finish, utilizing either High Pressure-High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods to grow the diamonds.
• HPHT diamonds form under pressures of approximately 1.5 million pounds per square inch and temperatures over 2,000 degrees Fahrenheit, using large mechanical presses to create these conditions.
• CVD diamonds grow in heated chambers at around 1,500 degrees Fahrenheit, where carbon-rich gas deposits layer by layer onto a thin diamond seed, building the crystal one atomic layer at a time.
• Lab-created diamonds undergo the same cutting, polishing, and grading processes as natural diamonds, adhering to identical quality standards and certification procedures.
• These diamonds can be created in a wider range of colors than typically found in nature, as the growth conditions can be precisely controlled and modified.
• Every lab-created diamond has a unique microscopic inscription identifying it as laboratory-grown, ensuring complete transparency in the market.
• The production process requires significant technological investment and expertise, with only a handful of facilities worldwide capable of producing gem-quality diamonds.

Laboratory-created diamonds have revolutionized the diamond industry by providing an alternative that maintains all the physical and optical properties of natural diamonds while offering different advantages in terms of origin traceability, environmental impact, and cost. These gems represent the intersection of traditional luxury and modern technological innovation, providing consumers with more choices in the diamond market.

Natural vs Lab Diamonds: Main Differences

When examining natural and lab-created diamonds, their similarities are far more numerous than their differences. Both types possess identical physical properties, sparkle with the same brilliance, and face similar quality assessments. Understanding how these diamonds compare across various factors helps provide a clear picture of what each option offers, allowing for an informed decision based on individual priorities and values.

• Physical durability and structure are identical in both types, scoring 10 on the Mohs hardness scale and featuring the same crystalline structure. This means both can be worn daily in jewelry, resist scratching equally well, and maintain their brilliance over time. The only way to distinguish between them is through specialized laboratory equipment that detects subtle growth pattern differences.
• Professional grading standards and certification processes remain the same for both varieties, using the 4 Cs scale (Cut, Color, Clarity, and Carat weight). Major gemological laboratories like GIA and IGI use identical grading criteria, ensuring consistent quality assessment regardless of origin. Both types can achieve the highest quality grades, with factors like cut quality having more impact on beauty than origin.
• Price differences are significant and consistent across the market, with natural diamonds typically costing 40-50% more than lab-created diamonds of equivalent quality. This price gap exists due to natural diamonds’ mining costs, limited supply, and traditional market position. However, lab diamonds’ prices continue to decrease as technology improves, while natural diamond prices generally remain stable or increase over time.
• Environmental impact varies substantially between the two types. Natural diamond mining impacts about 100 square feet of land per carat and uses approximately 126 gallons of water per carat mined. In contrast, lab-created diamonds require significant energy (approximately 250 kilowatt-hours per carat) but have a smaller physical footprint and use substantially less water. Both industries are actively working to reduce their environmental impact through improved practices and renewable energy sources.
• Market value retention shows notable differences over time. Natural diamonds typically maintain 50-60% of their purchase value, depending on market conditions and stone quality. Lab-created diamonds, while more affordable initially, may depreciate more quickly due to declining production costs and increasing supply. This factor becomes particularly important for those considering their diamond as an investment or family heirloom.

The comparison between natural and lab-created diamonds reveals that while they share identical physical and optical properties, their differences lie primarily in their origin, cost, environmental impact, and market position.
