Our Gemstone Selection

Almandine Garnet

This gemstone is of the garnet group. Almandine has the distinction of the most widely used garnet in the jewelers industry. This gemstone is among the most popular dark-red options.


Pearls

We have a selection of many different sizes of natural and artificial pearls. A pearl is produced in the soft tissue of a living shelled mollusk. Our freshwater pearls are among the highest quality and affordable.
Historically Japan held the pearl market. In recent years China has taken it over. With Chinese Cristaria Plicata mussel being able to produce 50 low quality pearls at a time the market at one point was flooded with ‘rice krispie pearls.’ This has changed over the years. China shifted production to Hyripsis Cumingii mussel, producing less at much higher quality.
Contains a hardness of 2.5 – 4.5 on the Mohs scale. This varies widely due to the organic nature of pearl production.


Peridot

One of the few gemstones that only occurs in one color. This intensity depends on how much iron is contained. This gem is commonly mistaken for emeralds due to the olive green color. This gemstone is easy to care for and considered an ideal summer stone. This stone is of august and carries the month well.
Contains a hardness of 6.5 – 7 on the Mohs scale.
