(PRESS RELEASE) NEW YORK — K. Rosengart, a diamond melee supplier with 28+ years of experience in jewelry design and manufacturing, bench work and stone setting, has introduced diamond testing into its repertoire of services.

Said Karen Rosengart, founder and CEO of K. Rosengart, “We are committed to supplying our clients with the best quality diamond melee. Our diamond analysis service is a natural extension of that commitment.”

But the diamond analysis service isn’t limited to K. Rosengart’s clients alone.

According to Rosengart, “Even if a diamond is acquired from another source, we will screen it by request.”

The screening itself is conducted using the Yehuda Sherlock Holmes Detector, a state-of-the-art diamond testing technology capable of analyzing bagged, loose and mounted colorless and near-colorless diamonds for evidence of chemical vapor deposition (CVD) and high-pressure, high-temperature (HPHT) lab growth.

The presence of CVD and HPHT in diamond melee is a growing concern in the jewelry industry. According to the Gemological Institute of America, Inc., more than 200,000 carats of HPHT lab-grown diamond melee alone are produced every month. And, in some areas of the diamond market, those lab-grown diamonds are being mixed into loose melee diamond parcels.

Said Rosengart, “The mixing of lab-grown and natural diamonds has many concerned about quality when buying diamond melee. That’s why we take extra care in analyzing the diamond melee we supply to our clients.”

In addition to the Yehuda Sherlock Holmes Detector, the team at K. Rosengart uses an in-house microscope as well as automated M-Screen melee diamond testing technology to analyze the diamond melee it supplies.

Said Rosengart, “We guarantee 100% natural stones, while our precise orders with no minimums and free second day shipping ensure 100% satisfaction.”

When There’s No Succession Plan, Call Wilkerson

Bob Wesley, owner of Robert C. Wesley Jewelers in Scottsdale, Ariz., was a third-generation jeweler. When it was time to enjoy life on the other side of the counter, he weighed his options. His lease was nearing renewal time and with no succession plan, he decided it was time to call Wilkerson. There was plenty of inventory to sell and at first, says Wesley, he thought he might try to manage a sale himself. But he’s glad he didn’t. “There’s no way I could have done this as well as Wilkerson,” he says. Wilkerson took responsibility for the entire event, with every detail — from advertising to accounting — done, dusted and managed by the Wilkerson team. “It’s the complete package,” he says of the Wilkerson method of helping jewelers to easily go on to the next phase of their lives. “There’s no way any retailer can duplicate what they’ve done.”
