Tumbled orange-and-white feldspar-rich stone, likely sunstone or orange feldspar

Likely potassium feldspar (orthoclase or microcline), KAlSi₃O₈; exact identification is uncertain from the image

AI-generated identification · may be incorrect

Rounded and polished, with cream, peach-orange, and rusty-brown mottling and a vitreous-to-waxy luster. Feldspar has Mohs hardness 6, a triclinic or monoclinic crystal structure, and two cleavages near 90°; the stone’s appearance alone cannot confirm its composition.

AI Estimated Value

About $2–$15 for a small, common tumbled specimen; higher prices require confirmed identity and notable gem quality.

Physical properties

Formation & geological history

Feldspar commonly crystallizes as magma cools in igneous rocks, and may also occur in metamorphic rocks. The specimen has been tumbled; its geological age and source cannot be determined from the image.

Uses & applications

Used in glass and ceramics; attractive feldspar-rich stones are collected or made into inexpensive jewelry and polished ornaments.

Geological facts

Orange feldspar is sometimes sold as sunstone, but the image does not show enough detail to confirm the characteristic glittering inclusions that define gem-quality sunstone.

Field identification & locations

A hardness test, close inspection for feldspar cleavage, and gemological examination can help distinguish feldspar from quartz or other tumbled stones. Feldspar is widespread worldwide, especially in granites and pegmatites.
