Natural vs. Lab-Grown Diamonds in Davenport, Iowa
Natural and lab-grown diamonds are both real diamonds, but they differ in origin, rarity, price, and long-term market behavior. At Expressions Jewelers in Davenport, we help clients from across the Quad Cities compare both options and choose the diamond that best fits their priorities.
✓
Are Lab-Grown Diamonds Real?
Yes. Lab-grown diamonds have essentially the same chemical, physical, and optical properties as natural diamonds. Both are made of carbon arranged in a crystal structure, giving them the brilliance, hardness, and appearance associated with diamond.
The Key Difference
How They Are Formed
Earth-Formed
Natural Diamonds
Natural diamonds formed deep within the Earth under extreme heat and pressure. Most are hundreds of millions to billions of years old and were carried toward the surface through ancient volcanic activity.
Technology-Grown
Lab-Grown Diamonds
Lab-grown diamonds are created from a diamond seed using advanced technology. High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) recreates the conditions needed for diamond crystal growth in a much shorter period of time.
Identification Matters
Can You Tell the Difference?
Not reliably by sight. Because natural and lab-grown diamonds have essentially the same appearance, trained jewelers generally need specialized screening equipment or an independent gemological laboratory to determine origin.
A grading report identifies whether a diamond is natural or laboratory-grown and documents important quality characteristics. Many graded diamonds also carry a microscopic laser inscription on the girdle that can be matched to the report number.
A Personal Decision
Why Choose One Over the Other?
There is no one-size-fits-all answer. The right choice depends on what matters most to you.
You may prefer a natural diamond if...
You are drawn to its ancient, Earth-formed origin, geological rarity, and established place in the traditional diamond market.
You may prefer a lab-grown diamond if...
You value its technological origin and the ability to choose a larger or higher-quality diamond within a particular initial budget.
Natural and lab-grown diamonds are priced in different markets. Purchase prices and potential resale values can change, so neither should be presented as a guaranteed financial investment.
