We found another pair of small Watermelon Tourmaline wings, so we’re making a new ring with them. We have a large pair coming in a pendant soon as well. With unusually shaped gem projects, our designer first makes a virtual model of the gems and forms the jewelry around it. That way we can make jewelry with delicate materials using gentle setting techniques and protective metal edges that fit perfectly and don’t require too much force to jam into place.

Here’s a sneak peek at gems we’re dreaming up designs for right now

Emerald is a famous shade of green, but what color does that really mean? Emerald green is vibrant and deep with a hint of blue, like the gem in the center of this video. Emeralds can be deeper and foresty, even more bluish, or more pure green like the gem on the right. Like all rare gems, the gem industry has decided on one shade of green as the most ideal Emerald green, the very best color. Those are going to be the most expensive. But you might like a darker and more dramatic color, or a lighter color that allows for more light and sparkle. Those will be less expensive, so we like to say that means your favorite is always on sale. may

This month join us as we get up close, closer, really close! to one of our favorite gems, May’s birthstone, the Emerald. For natural colored gems, the most important factor in their value is their color. Some gems are almost always filled with inclusions, little crystals or cracks and fissures that you can see with the naked eye. A gem like this one with bright, rich green color is still rare and valuable, even without great clarity. Emerald lovers recognize the charm of those “imperfections” and even have a name for this, the jardin or inner garden of each Emerald. gemeducation may

Diamond month is almost over! People ask us sometimes if we carry lab grown Diamonds. Yes! We’re always happy to order them for you. When you see jewelry in our store, all the gems are natural. We have recycled natural diamonds in our vault ready to make into new jewelry too. Why don’t we stock lab grown Diamonds? It’s because they continue to come down in price. We don’t want to have inventory in stock that’s more expensive than it should be. We’d rather order you exactly what you want at the best price. Modern Diamond growing machines are a pretty new invention, so people are still getting into the business of making Diamonds with them. We expect the prices to keep doing down until they find an equilibrium between factories and buyers.

Both the center stone of this ring and the loose gem are natural Diamonds. They have the same round shape, same number and arrangement of facets, and they weigh within 0.03 ct of each other. Why is one so much more sparkly? It’s the clarity! The loose Diamond has many more inclusions, so many that it interferes with the light that could be bouncing through to make sparkles. It was graded as I2 (Included 2) in clarity, much more included than the other gem’s grade of VS2 (Very Slightly Included 2). What are inclusions? Those are cracks, dark crystals, or other visible artifacts of how the Diamond grew in the Earth. Almost all natural Diamonds have these, and some inclusions can be beautiful under magnification. Natural Diamonds with fewer inclusions are more rare and more sparkly, so they cost more. Mardon recommends diamonds in the Slightly Included (SI) or Very Slightly Included (VS) grades because we think they offer the best combination of beauty and value. At the highest end of clarity, you are paying for rarity that is only more beautiful under a microscope.

It’s a gray day but it’s still Diamond month! Enjoy this big sparkler and put some sparkle into your Saturday! This month we’ve been posting about why Diamonds are so special. The hardness and durability we’ve posted about allows them to have another special quality: history. Diamonds can be worn in jewelry and last a lifetime. That means you can have Diamond jewelry from a place you visited long ago and enjoy it years later, with all the memories you made then and along the way. You can inherit Diamond jewelry and remember the person that wore it first. Even as the settings wear out, you can set those Diamonds into new settings and remember those people and places. Your style changes over your lifetime, but you can keep restyling your Diamonds so they fit the current you. But the history they have with you keeps going.

April is Diamond month, and one less obvious reason they are so awesome is that they go with everything. Every color, every texture, every shape! This is what makes them a wardrobe staple. If you’re investing in a small, versatile fine jewelry collection you might start with Diamond stud earrings. If you love colored gems, Diamonds are the perfect background singers to add sparkle without clashing. Bonus fact! Clear sparkly Diamonds are super versatile, but Diamonds can also be found in the Earth in every color 😮 Colorful natural Diamonds are very, very rare and range from whoa $$$ to astoundingly expensive.

Whoa! April is Diamond month, so why are we featuring a colored gemstone ring?? This ring was a gift to our customer for her 25th wedding anniversary, and she’s worn it daily since then. She’s celebrating her 50th anniversary on a cruise soon. The center gem here is Tanzanite, a gem famous for its violet blue color. You might have also heard that Tanzanite is soft. This Tanzanite still has beautiful color, but it’s lost its sparkle! Because it is soft, the gem has gotten scratched and abraded, giving it a fuzzy look. You know what gem is the very best for daily wear? That’s right, Diamond! Diamond is the very hardest natural material. In our last post we learned how incredible hardness allows us to polish each flat Diamond facet to a perfect shiny and reflective finish, producing flashing sparkling light. It’s the edges of the facets that show off Diamond’s wear advantage. Instead of getting countless nicks and nibbles, those edges stay straight and crisp. You might get a few tiny nibbles on the thinnest edge of a diamond over 25 years, but these are chips and not scratches. At Mardon we often see diamonds worn daily for multiple lifetimes without scratches on the exposed top (the crown). No scratches = outstanding long term sparkle production!

April is Diamond month, so check out this video of some of our in-stock natural Diamond rings in the sun. That shimmying twinkle and sparkle is just so beautiful! There are two things that make Diamonds have that heart-tingling brilliance. One is that they are unbeatably hard. That hardness means you can polish a Diamond to a literally incomparably perfect shiny finish. There’s even a special name for it, an adamantine (meaning diamond-like) luster. When light bounces off a finished facet and hits your eye you get a *pow* and the tingles start. –But what really gets us going is the combination of white and rainbow sparkles. The colored sparkles happen when light passes through the Diamond and the light refracts. It *boing* bounces off the back facet to return to your eye. The diamond causes the light to bend a lot as it travels through, so this *pow* is going to come back to your eye as colored light. Lots of perfectly angled facets with that incredible polish, and you get a stupendous display of sparkles. Bonus fact! You can bury all the edges of the diamond into metal, and still get all that sparkle and wow.
