Gemological Laboratory Opens in Manhattan

It’s located in the International Gem Tower on 47th Street.




(PRESS RELEASE) — SGL International, headquartered in London, with 15 diamond certifying laboratories worldwide, has opened its 16th lab and only location in the U.S. The facility is located in the International Gem Tower on 47th Street in Manhattan’s diamond district.

“Opening a new lab in the competitive US market, especially in New York City, we knew it was essential to distinguish SGL from all other labs,” said Shirin Bandukwalla, co-director, SGL Worldwide. “We needed to do more than merely provide services to the industry. It was critically important to identify and create solutions for jewelry retailers, while at the same time provide the ultimate assurance and confidence for the end consumer.”

SGL is able to assure consistent and accurate quality certification to its customers by having all 16 labs use the same technology, methodology and protocols for detection, grading, authentication and certification. This high standard international grading system practiced across the SGL network, separates them from all other gemological laboratories worldwide. And now the New York lab, with this exclusive range of specialized solutions that have already benefited retailers and manufacturers all over the world, will help the U.S. market overcome the logistical challenges often found when dealing with existing laboratories.

SGL Launches First-Ever Mobile Lab Service
SGL has launched the first-ever mobile lab service in the U.S., allowing retailers to have a team of SGL professionals visit their store(s) to screen, grade and certify finished diamond jewelry on-site. A new and unique alternative to shipping jewelry to the lab, the mobile lab is easy and convenient, providing retailers with an excellent opportunity to have more or all of their products certified at once. This service also includes the screening for lab grown vs natural diamonds.

SGL Introduces Lab Grown Diamond Screening and Identification Equipment
As part of its New York laboratory launch, SGL has also announced the introduction of “Dia Screen,” its laboratory grown diamond screening instrument. The unique machine screens for both CVD and HPHT lab grown diamonds, and natural diamonds. But it also isolates and identifies moisannite and cubic zirconia.

“We can’t underestimate the significance of separating HTHP from CVD lab grown diamonds,” said Chirag Soni, co-director, SGL Worldwide. “It’s no longer simply lab grown vs. natural. The growing price distinction alone will make it critically important for the industry to separate HPHT from CVD lab grown.” SGL believes this is the first, and perhaps only, machine that does this. Dia Screen is offered in two sizes (with identical technology), and currently available for sale at SGL New York. It will soon be launched across the laboratory’s worldwide network.


“I’m very excited to see the New York laboratory open. It further demonstrates SGL’s commitment to growth and expansion,” said Soni. “At SGL, we believe that successfully providing full-service solutions for our clients requires more than just knowledge and expertise. Our commitment to excellence, combined with our mission to deliver outstanding service, has earned our company the reputation it holds today.”

Wilkerson Testimonials

Why This Fourth-Generation Jeweler Chose Wilkerson for a Very Special Sale

Parian & Sons of Franklin Lakes, NJ was founded in the early part of the 20th century. But even stores that have successfully made it through the Great Depression, a World War and the Woodstock Generation must come to an end. With no family wanting to continue the tradition, the time was right for Glenn Parian and his wife, Maria, to retire. And what better way to do so than by hiring Wilkerson to help with the store’s liquidation sale. As Glenn puts it, with his credit card machine humming to the tune of up to 200 transactions a day, he couldn’t have done it without Wilkerson. “This is what they do,” he says. “This is what they do for everybody.”
