Overview of Pink Gemstones
Pink gemstones range from soft pastels to vivid shades and are historically associated with royalty and spiritual values. They generally symbolize love, tenderness, and compassion.
Precious Pink Gemstones
- Pink Diamonds: Extremely rare, with only 1% of Australian natural pink diamonds being considered sellable. They are primarily sourced from Australia, with smaller amounts from Africa and Russia. Their color is caused by the absorption and refraction of light.
- Sapphires:
- Padparadscha Sapphire: The rarest variety, featuring a pinkish-orange to orange-pink hue reminiscent of the lotus flower. In Vedic astrology, it is linked to the planet Venus.
- Pink Sapphire (Gulabi Pukhraj): Color is derived from chromium trace elements; higher chromium levels result in deeper colors and higher value.
- Star Ruby: A unique variety of ruby that exhibits asterism (a three-point or six-point reflection) caused by rutile fiber inclusions known as "silk."
Semi-Precious Pink Gemstones
- Tourmaline: Includes Rubellite (a variety of elbaite), which gets its pink color from manganese.
- Quartz: Rose quartz is a popular, affordable light pink stone often characterized by a cloudy appearance due to inclusions. It has a Mohs hardness of 7.
- Spinel: Known for excellent clarity and rich color, ranking 8 on the Mohs scale.
- Topaz: A silicate mineral that gets its color from iron or manganese. Brazil is the largest producer (approx. 50%), followed by Pakistan and Russia.
- Garnet: Malaya garnets are linked to renewal, while Rhodonite Garnet (a pink pyrope variety) has a Mohs hardness of 7.5.
- Rhodochrosite: A calcite carbonate mineral found in solid pink or banded patterns. It is fragile (Mohs 3-4) and found in Peru, Bolivia, and Brazil. Colorado recognizes it as its official state mineral.
- Other Varieties: Pink Scapolite (can show a "cat's eye" effect), Pink Opal (national gemstone of Peru), and Kunzite.
