\"LasWhat do you think of when you hear the word Las Vegas?\u00a0 I know I think of sparkle, glitter, gold, diamonds, and the jewelry industry\u2019s most premier event: JCK Las Vegas<\/a>.<\/p>\n

This year it\u2019s being held June 5-8, 2017, and it\u2019s expected that over 30,000 of the world\u2019s most influential industry professionals will attend.\u00a0 You would think that with a show that big that everyone who likes jewelry would want to go.\u00a0 Well, they may want<\/em> to go, but they are not allowed to go.\u00a0 JCK Las Vegas is a trade event for qualified jewelry industry professionals only.\u00a0 You must provide a business license or sales tax certificate, invoices from jewelry suppliers, or some proof that you are a jewelry manufacturer or equipment supplier, or a professional in the diamond\/gem\/appraiser and jewelry industry. (You can check out their rules here<\/a>.)<\/p>\n

Luckily I get to see all those sparkly items because we will be exhibiting at Booth B66064 and helping to educate the industry professionals on how to verify precious metal content in their items. Both manufacturers and jewelry retailers need to make sure that the precious metals they use or receive from suppliers are actually what they think they are.\u00a0 Unfortunately, sometimes they are not.<\/p>\n

We have previously warned our readers about fake gold bead necklaces<\/a>, fake gold jewelry<\/a>, and silver \u00a0and gold-plated or copper counterfeits stamped 14K or 18K gold.\u00a0 Unfortunately, the scams and fakes are getting increasingly sophisticated. Normally to combat any losses, retailers test the jewelry several ways, including the sometimes unreliable magnet test and weight test, the dangerous scratch testing using acid, or cutting into the metal which of course cannot be done to jewelry that will be sold.<\/p>\n

To be absolutely certain of the composition of gold and other precious metals, many businesses are now turning to\u00a0X-ray fluorescence (XRF)\u00a0<\/a>technology.\u00a0\u00a0A Precious Metals XRF analyzer<\/a> utilizes this nondestructive metal purity analysis technology, and is available in both handheld<\/a> and desktop<\/a> models.<\/p>\n

We\u2019ll be demonstrating portable XRF technology and even inviting attendees to bring their jewelry to the booth to be analyzed for free.\u00a0 They will be able to learn in seconds the metal content of the piece.\u00a0 We can even precisely determine the presence and concentration of other trace alloying elements including lead.<\/p>\n

If you need to give your eyes a break from the glitter, visit Red Rock Canyon & Hoover Dam if you would like to venture out.\u00a0 If you\u2019re hungry while you\u2019re out, Ferraro\u2019s on Paradise Road<\/a>\u00a0is\u00a0just a few blocks off the strip. They make the best Ossobuco I have ever tasted.<\/p>\n

Hope to see you there, but if you can\u2019t make it, follow the show twitter feed at \u00a0#JCKLasVegas or click on this link to see how\u00a0XRF analysis compares with traditional acid testing<\/a>\u00a0in this 2-1\/2 minute video.<\/p>\n
