10.05 Ct. Cabochon Rutilated Quartz from Ceylon (Sri Lanka)

This smoky rutilated quartz offered by The Natural Gemstone Company is a transparent oval cabochon weighing 10.05 carat, with dimensions 27.76 x 17.29 x 5.90 mm. The stone exhibits a medium intense smoky tone that allows excellent visibility of the rutile needle network. The cabochon cut is particularly well chosen for this material, as the domed surface enhances the three dimensional appearance of the rutile inclusions and produces a soft, even luster. Polish is graded excellent, which contributes to strong surface reflection and tactile smoothness, and the gem is documented as having no enhancement, ensuring natural origin and intact crystal structure.

Clarity is graded very slightly included, evaluated at eye level, a classification that is especially desirable in rutilated quartz because the inclusions are the feature that gives the gem its character and value. The needled rutile forms a dense, intersecting pattern that reads as both aesthetic texture and natural fingerprint, and this patterning is consistent with material from Ceylon Sri Lanka, the stated origin. For an educated buyer, provenance from Sri Lanka matters because local geology produces rutile with fine, well defined needles and a balance between needle density and transparency. Quartz has a Mohs hardness of 7, which makes it durable for everyday wear when set properly, and the absence of heat or chemical treatments means the stone will age and respond to cleaning in a predictable manner.

From a practical and investment standpoint this stone combines attractive carat weight with collector appeal. The 10.05 carat size and oval proportions are well suited for statement rings, pendants, or museum style collections, and the excellent polish and natural rutile distribution command attention without artificial enhancement. At The Natural Gemstone Company we document the evaluation criteria including weight, exact dimensions, cut style, clarity grading as very slightly included evaluated at eye level, color intensity as medium, polish as excellent, enhancement as none, and origin as Ceylon Sri Lanka, so you can purchase with confidence. We recommend a protective bezel or low prong setting and routine gentle cleaning with warm water and mild soap to preserve surface polish and overall appearance.
