Diamond Testing at North Scottsdale Loan & Gold

If you’ve ever compared a natural diamond with a synthetic one side by side, the resemblance can be startling. Lab-created stones can exhibit as much—or even more—brilliance and fire than mined diamonds. That’s because both varieties are chemically composed of carbon. However, synthetic diamonds are created quickly in controlled environments, whereas natural diamonds take over a billion years to form deep beneath the Earth’s surface.

This makes it more challenging than ever to identify the difference. That’s why our team offers free diamond testing for loose stones or set jewelry. We can determine whether a gem is a moissanite, a lab-grown diamond, or a naturally mined diamond using advanced technology.

The Science Behind Diamond Testing

Diamond testing is more than just visual inspection. It involves examining the chemical structure, thermal conductivity, and optical behavior of the stone. Natural diamonds—classified as Type I diamonds—form under immense pressure and heat over geological timescales. These stones often contain nitrogen impurities, which can influence their color.

In contrast, lab-grown diamonds, including Chemical Vapor Deposition (CVD) diamonds, are created in laboratories and classified as Type IIa. They lack nitrogen and boron, which typically gives them a more colorless appearance. Although chemically and physically similar to natural diamonds, CVD diamonds do not carry the same value in the resale market.

Knowing this distinction is critical, especially if you’re selling jewelry. You can read more about the difference in diamond types on The Diamond Pro.

Our Diamond Testing Technology: Gemologis Vista Diamond Segregator

At North Scottsdale Loan & Gold, we use the Gemologis Vista Diamond Segregator, one of the most advanced tools available for diamond testing. This handheld device allows us to analyze both loose diamonds and mounted stones ranging from 0.02 to 12 carats.

Key features of our diamond testing equipment include:

• 92.5% accuracy across various diamond sizes and shapes
• Fast analysis with instant results
• Clear identification of natural vs. synthetic diamonds

The process takes only minutes and offers peace of mind—no more second-guessing whether your stones are earth-mined or lab-created.

Why Diamond Testing Matters in Scottsdale, Phoenix, and Paradise Valley

In a region like North Scottsdale, where luxury items are common and designer jewelry is prevalent, diamond testing is indispensable. Many clients own estate pieces, engagement rings, or heirlooms and aren’t certain of their value or authenticity. Others may be in the market to sell or pawn their diamonds and want assurance they’re receiving a fair offer.

At North Scottsdale Loan & Gold, we combine the latest technology with expert appraisals to deliver an honest and transparent evaluation—right on the spot. For those seeking pawn loans against diamond jewelry, this ensures maximum loan value based on accurate testing results.
