The Rio Gemstones team sees thousands, heck, tens of thousands, of gemstones every year. Rarely does a week go by that one of us doesn’t turn to the other and say, “Hey check out this cool inclusion…” Until this week, though, we had never seen (except in books) hematite needle inclusions inside an amethyst. Take a look and see what we found!
Stone setting is hard work. To master the necessary skills you’ll need precision, patience, and plenty of practice. Blaine Lewis, widely recognized as the premier diamond-setting instructor in the U.S. today, understands this and invented TrendSetter Wheels which allow students to repeatedly set stones without setting up an individual mounting for each stone. Learn more about Blaine’s genius Trendsetter Wheels today on The Studio.

Reports of undisclosed synthetic diamonds being sent in to GIA and other grading labs indicates that some people are striving to get false documentation to perpetrate fraud on the public.

Check out today’s post to learn more about this important consumer alert.

One question we’re often asked is where our gemstones come from, so I thought Rio Grande customers might like to know about an initiative we have been pursuing: buying gemstones from reputable firms and ensuring the production of those stones causes no human suffering. Here’s how we do it.
On The Studio today: We recently read that a diamond-grading lab reported getting over 600 synthetic diamonds without disclosure. You may or may not have heard something about this yourself but, either way, I urge you to read about it now. Diamonds are the life-blood for many jewelers, and any threat that the diamonds for sale in a store might be “fakes” could be a huge problem for everyone, be they a jeweler or a customer.
The supply of diamonds tends to be plentiful for small stones, but extremely tight on really big diamonds. Consider buying diamonds in off-target carat sizes to get more value! Our diamond experts are are always eager to help you find the best stone for your needs. Learn more about diamond demand & supply. . .
Would you consider buying a 1 carat diamond without a certificate? Most folks wouldn’t. Consumers rely on the objectivity of a third-party gem lab to tell them the properties of the diamond they’re considering. So it is especially damaging to know that some diamond grading labs don’t do an ethical job when grading the diamonds. . .
Questions arise daily about the various scales we use in the jewelry business. Gold is weighed on a pennyweight or gram scale. Gems are weighed on a carat scale. Postage is weighed on an avoirdupois scale and pearls are sometimes weighed on a momme scale. Do you know if you are using an avoirdupois or a troy scale?
What’s happening is that most of the low-quality, inexpensive rubies now being sold in the market are not just “treated rubies” but something altogether different–a mixture of low-quality corundum infused with lead-glass. The amount of lead-glass present in the stones now in the marketplace often exceeds 25% and, in many cases represents 40% or more of the entire stone!
