Precious
Precious stones are distinguished by their quality, their rarity, and the beauty of their colors. There are only four precious stones: diamond, sapphire, ruby, and emerald. All other stones are therefore called semi-precious stones.
Semi-precious
Semi-precious stones are any other gemstone except precious stones. They can have colors not typical for precious stones, like purple and yellow. Semi-precious stones are divided into minerals, rocks and aggregates, and organic materials.
Precious Stones
When determining the value and quality of a precious gemstone, color is the primary characteristic to consider. Gemologists divide gemstone color into hue, tone, and intensity. The most requested precious gemstones are sapphire, ruby, and emerald.
Sapphire
Blue sapphire belongs to the mineral species corundum. It can be pure blue but ranges from greenish blue to violetish blue. The name “sapphire” can also apply to any corundum that’s not red and doesn’t qualify as ruby, another corundum variety. Sapphire is the birthstone for September and the gem of the 5th and 45th anniversaries.
Ruby
Rubies can command the highest per-carat price of any colored stone, which makes the ruby one of the most important gems in the colored stone market. Traces of Chromium give this red variety of the mineral corundum its rich color. In ancient Sanskrit, ruby was called ratnaraj, or “king of precious stones.” Ruby is the birthstone for July and the gem for the 15th and 40th anniversaries.
Emerald
Emerald is the bluish-green to green variety of beryl, a mineral species that includes aquamarine. Emerald was once cherished by Spanish conquistadors, Inca kings, Moguls, and pharaohs. Today, fine gems come from Africa, South America, and Central Asia. As the gem of spring, emerald is the perfect choice as the birthstone for the month of May. It’s also the gem of the 20th and 35th wedding anniversaries.
Semi-Precious Stones
Semi-precious stones come from all three possible types of geological formation: igneous, metamorphic, and sedimentary. So, they usually come from any environment and can be found worldwide. The main differences between precious and semi-precious stones are transparency and hardness.
Trending Semi-Precious Stones
Amethyst
As the most valued quartz variety, amethyst is in demand for designer pieces and mass-market jewelry. Its purple to pastel hues retains broad consumer appeal. Amethyst is the birthstone for February and the gem for the 6th and 17th wedding anniversaries.
Morganite
Part of the beryl family, like emerald and aquamarine, however, this gemstone is favored for its pink to orange-pink color, caused by trace amounts of the element manganese. However, unlike emeralds, which tend to have many inclusions, morganite gemstones are relatively free of inclusions, making them more eye-appealing and requiring less care.
Topaz
Honey yellow. Fiery orange. Cyclamen pink. Icy blue. In warm or cool tones, topaz is a lustrous and brilliant gem. Precious topaz is a birthstone for November, and blue topaz is a birthstone for December. Blue topaz is the gem of the 4th anniversary, and Imperial topaz is the gem of the 23rd anniversary.
