Gemstone Collection Appraisal

Assorted Tumbled and Raw Gemstones Collection

This collection consists of six individual gemstones, displaying a variety of colors, forms, and finishes. Three of the stones appear to be tumbled and polished, exhibiting smooth, rounded surfaces characteristic of this finishing technique, while two are more naturally 'raw' or minimally processed, retaining their crystalline forms. One stone is a translucent, cloudy white to light grey, suggesting a possible 'milky quartz' or similar variety, with a high polish and smooth, rounded edges. Another is a deep, rich indigo blue with white or lighter blue inclusions and veins, consistent with Sodalite, also highly polished and tumbled. A third tumbled stone is a mottled lavender and off-white or light grey, exhibiting a pleasing oval shape, potentially Lepidolite or a variegated form of Quartz such as Amethyst. In contrast, there is a distinct black stone with prominent vertical striations and a more rough, raw texture, indicative of Black Tourmaline (Schorl) in its natural columnar crystal form, which has not undergone tumbling. Another black, polished, and irregularly shaped stone could be Obsidian or Black Onyx, displaying a smooth, reflective surface. The sixth stone is fully translucent and colorless, with a clear, smooth, and tumbled finish, strongly suggesting Clear Quartz. The stones vary in size, generally appearing to be small enough to be held comfortably in the palm of a hand, likely ranging from approximately 1.5 cm to 4 cm in their longest dimension. No visible damage such as chips or significant scratches is evident on the tumbled stones, indicating good condition. The raw Tourmaline appears to be in its natural state. There are no discernible manufacturer's marks or signatures. The collection represents common forms of semi-precious stones, often sought after for their aesthetic appeal or perceived metaphysical properties. The combination of polished and raw specimens offers a contrast in textures and forms. The overall craftsmanship for the tumbled stones is of good quality, achieving a smooth, lustrous finish.
