Early in this century jewelers got together and created a new list of birthstones. In the modern list you will find only transparent gems. This makes it much easier to create a mothers ring. Imagine if you needed a pearl, a cabochon of turquoise, a diamond and an emerald. This would be an awkward thing to make look nice.
Another interesting point is the addition of alexandrite. This is an incredibly rare gem and not readily available.
The ancient list is still used considerably. Many people mix the two as they feel best. This is acceptable, the modern list has not replaced the ancient one, but supplemented it.

June – Pearl
Pearls are the only gems found within living creatures, both salt and freshwater mollusks. However, most pearls on the market today are cultivated, since they now occur extremely rarely in nature. While they require special care, pearls have an enduring appeal for jewelry, particularly as the traditional June birthstone.
Color: Pearl color is the result of a body color and an overtone color or orient present as a lustrous sheen. The orient is the color seen as reflected by a diffuse light source. The rest of the color is due to the body color.
Crystallography: Amorphous. The aragonite in the nacre of a pearl is orthorhombic, with minute crystals radially oriented and a concentric structure.
Modern List – Alexandrite
“Emerald by day, ruby by night,” alexandrite is well known for displaying one of the most remarkable color changes in the gem world — green in sunlight and red in incandescent light. However, the modern June birthstone is so rare and expensive few people have seen a natural alexandrite. That is why we are displaying Pearl instead, as it’s a much more attainable item.
