This 1.22 carat natural vivid red ruby is an untreated gemstone selected for its strong color saturation and elegant round mixed cut. Measuring 6.88 x 6.98 × 3.15 mm, the stone offers lively brilliance and balanced proportions, making it an excellent choice for refined fine jewelry.

The ruby displays a vivid red hue, a color segment commonly referred to in the trade as pigeon blood. This designation reflects saturation and vibrancy rather than origin and is used here strictly as a descriptive term. The stone’s transparency and overall quality contribute to a clean, bright appearance suitable for everyday wear as well as bespoke jewelry designs.

According to the C. Dunaigre Consulting (Switzerland) gemstone report, the ruby shows no indications of heating. The absence of thermal treatment preserves the stone’s natural integrity and is a key quality factor for clients seeking untreated rubies from recognized sources.

The stated Mozambique origin places this ruby among the most important modern sources of fine-quality material. In this size category, the stone is positioned as a high-quality, certified ruby for fine jewelry, rather than as an investment-oriented asset.

This ruby is ideal for clients who value natural origin, vivid color, and transparent certification, and who are seeking a refined gemstone for bespoke rings, pendants, or heirloom jewelry.

Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Ruby is the red variety of the mineral corundum, valued for its rich color, durability, and long-standing historical significance. Its color ranges from pinkish red to deep red, with hue, tone, and saturation playing a key role in its visual character and overall appeal.
Chemically composed of aluminum oxide (Al₂O₃), ruby crystallizes in the trigonal crystal system and belongs to the oxide mineral group. In gem-quality material, ruby typically displays a vitreous luster with transparent to translucent clarity.
The refractive index of ruby generally ranges from approximately 1.76 to 1.77, producing a restrained brilliance that emphasizes depth of color rather than strong sparkle. Rubies are found in several regions worldwide, with notable sources including Myanmar, Mozambique, Thailand, Sri Lanka, and Madagascar, each associated with distinct visual characteristics.

Durability & suitability

With a hardness of 9 on the Mohs scale, ruby offers excellent durability suitable for everyday jewelry when properly set and worn with standard care. Its high resistance to scratching and lack of cleavage make it one of the most robust colored gemstones used in jewelry.
Ruby performs exceptionally well in rings, pendants, earrings, and bracelets, including designs intended for frequent wear. While natural inclusions are common and expected in ruby, thoughtful setting design can help protect the stone and preserve its appearance over time.
