3.) Gemological and Chemical Composition Characteristics of Basalt-Related Rubies from Chanthaburi-Trat, Thailand

The geographic origin determination of ruby is increasingly important in the gem trade and geological research. Unlike metamorphic-related ruby, the rarer basalt-related ruby has gained significant attention, especially from Thailand, a major producer of such gems.

Our Feature Story
Indian Diamond Dealers Claim U.S. Harassment Over Russian Diamond Imports
Legal or not, is that your line in the sand?
Russian diamonds being cut in India are being purchased through bank accounts from company offices in Dubai.

The USA Office of Foreign Assets Control blocked payments to Russia totaling $26 million, claiming sanction violations. Indian cutters are not happy.

Sitting next to an Indian diamond manufacturer at the recent Harvard Jewelry Summit, this issue was privately discussed. According to the manufacturer, yes, they do purchase rough from Russia, as it is still legal to do so in India. But if they are selling their finished goods to a company that is headquartered in a country that has levied sanctions against Russia, they will be certain to sell them only goods gathered from other sources.

Am I supposed to be comfortable with that?

The Battle Still Rages!
A Give Away - Lab Grown Diamonds For FREE
Steven Singer Jewelers promotes natural diamonds
Steven Singer Jewelers, a name well-known in the jewelry industry, known for Ad campaigns like, “I Hate Steven Singer,” and “Does Size Matter,” has announced an extraordinary initiative. Steven Singer has what only five years ago was "$3 million worth" of lab-grown diamonds, and today he’s giving them away.

RGNR - Working the Math. A hundred 50-pointers for $3 million = $60,000/carat. With a little assistance from our friends at Gemworld, we found that in 2019, prices were roughly $3,000/carat.

The jeweler who sells nationally online, with a brick & mortar flagship store in Philadelphia, aims to celebrate its unwavering commitment to Earth Born DiamondsTM and educate how the mass production of lab grown diamonds has caused their rapid decrease in value by roughly 90 percent, making them almost worthless.

Steven Singer, the founder and CEO of Steven Singer Jewelers, expressed his excitement by saying, “Steven Singer Jewelers doesn’t believe in lab grown diamonds because they lack what makes Real Natural Earth Born Diamonds so special: the incredible formation over millions, if not billions, of years,” said Steven Singer. “There’s been a debate in the industry, but I knew anything that can be mass produced infinitely will rapidly lose value, which is exactly what happened as production scaled. Lab grown diamond value continues to plummet and I just don’t feel right about selling them knowing they will be worthless one day.”

Crystal pipes – are they actually safe to smoke?
Safe, or Not Safe?

Not a good idea!

When crystal pipes images hit influencer accounts, everyone was clicking “add to cart” at the online headshop. Crystal pipes are ethereal, drawing in people with myriad interior decor styles.

And touted as “all natural.”

These pipes provide the perfect visual for a layout or cannabis photoshoot and add a nice touch to a stoned night in with friends. The cute smoking accessory was built for the social media era, and it showed.

Soon after the first lovely pipe hit the market, they were everywhere. Today, a quick Etsy search yields over 3000 results. They’re clearly popular, but is it safe to smoke from them?
