4.05 Ct. Ruby from Mozambique

This GIA certified ruby presented by The Natural Ruby Company is a remarkable transparent red specimen weighing 4.05 carats, fashioned into a classic pear silhouette measuring 13.34 by 8.27 by 4.44 millimeters. The gem has been cut as a mixed brilliant, combining a faceted brilliant crown with a carefully proportioned pavilion that favors both color saturation and light return. The cutting laboratory report from GIA confirms eye clean clarity when evaluated at normal viewing distance and assigns a vivid color intensity, attributes that together produce a visually commanding presence in this size class. The stone has undergone standard heat treatment, a stable and industry accepted enhancement applied to maximize color uniformity and reduce less desirable inclusions, and the surface finish is executed to an excellent polish, delivering crisp facet junctions and an immediate sense of depth and brilliance.

From a technical standpoint the proportions of this pear shaped ruby are engineered to balance face up color and scintillation. The length to width ratio of approximately 1.61 renders a proportionally elegant pear form, while the measured depth relative to the average diameter is approximately 41 percent, a profile that mitigates windowing and preserves strong color saturation across the table. The mixed brilliant faceting places emphasis on a brilliant crown facet pattern that disperses white light as scintillation and fire, and a pavilion arrangement that redirects light back through saturated red hues rather than leaking as wasted light. Chemically the chromophore is chromium with trace iron content typical of Mozambican rubies, which together produce the described vivid red, enhanced under short wave ultraviolet light by a strong red fluorescence that contributes to perceived warmth. Optical parameters for ruby in general apply here, with refractive indices in the range of 1.762 to 1.770 and birefringence around 0.008 to 0.010, factors that influence facet orientation and polish protocols during lapidary work.

Durability and setting considerations are central when transforming a significant stone into a piece intended to be worn over generations. Ruby rates nine on the Mohs hardness scale, providing excellent resistance to abrasion in everyday wear, yet it remains prudent to protect the vulnerable pointed end of the pear through thoughtful mounting techniques. A tapered V style prong or a custom bezel at the tip will safeguard the point from impact, while a three or four prong head will balance security with light access to the pavilion and crown. Platinum and 18 carat gold are preferred metals for heirloom commissions because of their long term stability and compatibility with professional resizing and conservation work. Cleaning may be accomplished with warm soapy water and a soft brush, and because this ruby is heat treated and not glass filled, professional ultrasonic cleaning is generally safe but should be performed under technician supervision and followed by routine inspections of the setting and tips.

Beyond its immediate aesthetic merits this ruby has the essential attributes that allow it to mature into a true generational heirloom. The combination of a verified GIA report, a compelling carat weight above four, vivid natural color, and eye clean clarity places the piece in a market segment sought by collectors and connoisseurs, improving liquidity and long term desirability. Origin from Mozambique is increasingly recognized for producing richly colored rubies with attractive crystal habit, and documented provenance from The Natural Ruby Company will accompany the gem, preserving the chain of custody and simplifying future appraisals, insurance and conservation decisions. The mixed brilliant cut ensures the stone can be reset or reimagined without significant sacrifice to material loss, permitting future owners to adapt the piece while preserving the integrity and story of the ruby. With appropriate setting and routine maintenance the stone will resist the wear of daily life, while the emotional and monetary value it accrues can be transmitted intact to subsequent generations, making this pear shaped Mozambique ruby a practical and meaningful candidate for an heirloom that endures both in physical form and in family history.
