How Precious Am I?

What do Imperial jadeite, black opal, demantoid garnet, and alexandrite all have in common? First of all, they are all exceptionally rare gemstones. Second, they can command thousands to tens of thousands of dollars to even millions of dollars per carat.

Summer Jewelry Care

Summer has finally settled in. Summer activities abound with the sun out, so it’s worth mentioning that some jewelry needs to be treated a little differently during the fun things we all love to do when it gets beautiful outside.

May’s birthstone: the lovely emerald..green fire.

I first got turned on to emeralds in Munich, Germany, while walking through a museum housing some of the most fantastic pieces I had seen. I remember being in a short passage (lined with cases of incredible jewelry) and glancing to my left seeing green fire. The emerald in the collection was a square emerald…
