(upbeat music) – This is Jill Maurer
with Your Jewelry Minute, and today I’m answering the question, what is a bicolor stone? Gemstones get their color, usually, from trace elements in the
earth as they’re forming, and those trace elements
determine the color of the stone. If the trace elements change, if there’s a sudden change to
what trace elements are around as the stone is being formed, the color can suddenly change, and it can be a very clear line where a stone suddenly goes,
say, from green to red, and that is known as a bicolor stone. One of the most common
bicolor stones you’ll find is an ametrine, and that is a stone that suddenly changes from
amethyst, which is purple, to citrine, which is yellow, and so you’ll have purple
and yellow in the same stone. It doesn’t mean that it’s
divided right down the middle. It could happen anywhere in the stone, but you’ll see a clear delineation. Other stones that you will sometimes find as bicolor stones include
tourmaline and sapphire. Almost any stone can
create a bicolored stone. Topaz, tourmaline, sapphire, and sometimes the color isn’t
just clearly down the middle. It can be a big sort of chunk, one area of the stone that
has a different color, and we would still call
that a bicolor stone. This has been Your Jewelry Minute. If you have a jewelry question for me, just let me know in the comments below. Until next time. (upbeat music)


  1. You did a video a while back where you talked about watermelon tourmaline and after I watched that I saw them at TJ Maxx of all places. I really like these bicolor stones. That gold and silver one you showed is so pretty. Thanks for teaching us about them!

  2. So funny you did this video today! I’ll definitely have to include this in my video…. thanks Jill! I hope you have a great day and I CANT WAIT for tomorrow’s Monday musing!

  3. I have always wanted a watermelon tourmaline. For years I've wanted one, but they are terribly pricey now. Should have purchased one back in the day! September is almost over, keep up the great work!

  4. I’m a big fan of the watermelon tourmaline. It’s so different and pretty. Also, being an October baby, pink tourmaline is my alternate birthstone.Maybe you could do a video on birthstones and their alternates.
