1.31 Ct. Ruby from Mozambique

One transparent oval ruby of 1.31 carat, presented with exact dimensions of 6.83 by 5.72 by 3.50 millimeters, exhibits a vivid red tone and a mixed brilliant cut designed to maximize light return. The clarity grade is very slightly included as evaluated at eye level, indicating exceptional transparency for a natural ruby of this size. The polish is excellent, and the finishing facets display crisp, well defined facet junctions that contribute to the gem s overall brilliance. The stone has been heat treated, a stable and widely accepted enhancement in the trade that has been applied to improve color uniformity and overall visual appeal, and the documented origin is Mozambique, a source known for producing rubies with strong, saturated red hues and good crystallographic quality. The Natural Ruby Company provides this description based on direct examination and photographic documentation, and the images reflect the gem s rich, saturated color and even tone.

This ruby is notable for its relative rarity when both size and color are considered together. In the current market, rubies exhibiting vivid color intensity combined with transparency and a carat weight above one carat are significantly less common than smaller stones or stones with less saturated color. Many rubies that reach similar weights tend to show increased body color that shifts toward darker or brownish red, or they display more prominent inclusions that reduce transparency and brilliance. Conversely, rubies with the vivid pigeon s blood or pure red tones that collectors and connoisseurs favor are frequently found in sizes below one carat, where clarity and color saturation often appear most intense. This 1.31 carat specimen therefore occupies a narrow segment of supply where a desirable combination of vivid color, eye level clarity that is very slightly included, and a clean mixed brilliant cut converge, making it materially rarer than more commonly encountered alternatives in both commercial and collector markets.

From a practical and design perspective the stone s oval outline and mixed brilliant pavilion allow for versatile use in fine jewelry, including classic solitaire rings, refined pendants, or bespoke engagement settings where the ruby is intended to be the primary visual focus. The proportions support secure bezel or prong settings while preserving light performance, and the excellent polish enhances faceting contrast to deliver a lively face up appearance. Because the treatment is heat only, standard precautions for everyday wear and routine jewelry maintenance apply, and the stone responds normally to conventional cleaning methods recommended for corundum. For clients and designers seeking provenance, the Mozambique origin contributes to the gem s character and market position, as Mozambican rubies are appreciated for their rich red palette and crystal clarity relative to many other deposits.

The Natural Ruby Company stands behind the accuracy of the description and the presented imagery, and we emphasize transparency regarding enhancement and origin in all listings. For buyers prioritizing rarity in both color and size, this ruby represents an uncommon alignment of attributes that are typically at odds with one another in the market.

This presentation is intended to provide a clear and factual assessment of the gem s physical characteristics and market significance, enabling an informed decision based on quality, provenance, and the distinctive combination of vivid color and above one carat weight.
