0.70 Ct. Ruby from Thailand

This transparent 0.70 carat pear shape ruby presents a refined pinkish red hue with intense color saturation, precise proportions and a mixed brilliant cut that maximizes light return. The stone measures 6.19 by 4.33 by 3.20 mm, and its excellent polish enhances surface brightness and facet contrast. Clarity is graded slightly included, evaluated at eye level, which contributes to the ruby s natural character while remaining attractive when set. Heat treatment has been applied, a common and stable enhancement that improves color uniformity and is disclosed in our description. Origin is Thailand, a source known for producing rubies with lively color and good cutting potential. The Natural Ruby Company provides this gem ready for secure mounting in fine jewelry, where its pear silhouette is suitable for rings, pendants and earrings.

Regarding durability, ruby is corundum and ranks nine on the Mohs hardness scale, offering exceptional resistance to scratching for daily wear. The excellent polish and mixed brilliant cutting enhance this resistance by reducing microabrasion on facet surfaces, and the stone s transparency supports visual depth without compromising strength. Slight inclusions should be considered when planning a setting, because while corundum lacks true cleavage, inclusions can influence toughness in localized areas. For everyday use we recommend protective mounting practices that minimize exposure to impact at the pointed end of the pear, such as a secure bezel or a well-designed prong setting that supports the girdle and tip. Routine care is straightforward, consisting of warm soapy water and a soft brush to remove oils and grit, followed by gentle drying. Heat treated rubies are generally stable to normal jewelry cleaning methods, however ultrasonic or steam cleaning should be avoided if the stone shows significant internal fissures, and professional evaluation is advised before such treatments. With appropriate setting and sensible handling, this Thailand ruby will deliver enduring wearability and maintain its vivid presence in daily jewelry pieces. The Natural Ruby Company stands behind the described specifications and can advise on mounting options that optimize both appearance and protection.
