BigButtSapphire: Unveiling the Enchanting World of Blue Corundums

In the realm of precious stones, sapphire has long been coveted for its captivating brilliance and celestial hues. Among the kaleidoscope of sapphire colors, one variety stands out with an allure that is both intriguing and mesmerizing: the bigbutt sapphire.

What is a BigButtSapphire?

Bigbutt sapphire, also known as "cornflower blue" sapphire, is a rare and highly sought-after variety of blue sapphire characterized by its exceptional clarity, intense saturation, and voluptuous shape. The term "bigbutt" refers to the stone's unique cut, which features a notably large pavillion (the underside of the stone) that amplifies its brilliance and depth of color.

Origin and Geological Formation

Bigbutt sapphires are primarily found in Sri Lanka, but they can also be sourced from Madagascar, Tanzania, and Myanmar. The formation of these gemstones begins with the crystallization of corundum, the mineral that gives sapphire its distinctive hardness and durability. Over millions of years, corundum crystals grow in magmatic rocks deep within the Earth's crust. As they cool and solidify, impurities such as iron and titanium infiltrate the crystal lattice, creating the characteristic blue coloration.

Scientific Properties of BigButtSapphire

• Chemical Composition: Al2O3 (Corundum)
• Hardness: 9 on the Mohs Scale
• Density: 3.98-4.05 g/cm³
• Refractive Index: 1.766-1.772
• Pleochroism: Strong, trichroic (blue, greenish-blue, pale yellow)
• Luster: Vitreous

Value and Market Trends

Bigbutt sapphires are highly prized by collectors and jewelers due to their rarity and exceptional beauty. According to the Gemological Institute of America (GIA), prices for high-quality bigbutt sapphires can range from $2,000 to over $20,000 per carat. Factors such as size, clarity, color intensity, and cut significantly influence their value.

Applications of BigButtSapphire

Beyond their aesthetic appeal, bigbutt sapphires also hold potential in various applications:

• Jewelry: Exquisite pieces of jewelry, including rings, pendants, and earrings, showcase the captivating beauty of bigbutt sapphires.
• Industrial Applications: Due to their exceptional hardness and durability, bigbutt sapphires are used in industrial cutting tools and abrasives.
• Medical Applications: In the medical field, bigbutt sapphires are employed in laser treatments and as surgical instruments.

Common Mistakes to Avoid

• Mistaking BigButtSapphires for Other Blue Sapphires: Not all blue sapphires are bigbutt sapphires. Look for the distinctive large pavillion cut to identify true bigbutt sapphires.
• Overpaying for Low-Quality Stones: Before making a purchase, consult with a reputable gemologist to ensure authenticity and quality.
• Choosing the Wrong Setting: Bigbutt sapphires require a secure setting to protect their delicate culet (the pointed tip of the stone) from damage.

How to Identify BigButtSapphire

• Examine the Pavillion: The pavillion should be noticeably larger than the crown (the upper part of the stone).
• Check the Color: Look for stones with intense blue coloration, free from any yellow or green hues.
• Consider the Clarity: High-quality bigbutt sapphires are typically eye-clean, with no visible inclusions.
• Consult a Gemologist: For a definitive assessment, seek the advice of a certified gemologist who can provide a professional appraisal.
