1.54 Ct. Yellow Sapphire from Madagascar

This 1.54 carat radiant shape yellow sapphire is specified with exact measurements 6.74 by 5.47 by 3.99 millimeters, yielding a length to width ratio of approximately 1.23, which produces a visually pleasing, slightly elongated outline that sits elegantly in most ring and pendant designs. The depth to average dimension ratio calculates to approximately 65 percent, a proportion that balances color saturation with efficient light return for the radiant cut. The radiant cut employed here is a mixed facet architecture combining brilliant style facets on the pavilion and crown with trimmed corners and step elements near the girdle, producing lively scintillation and a broad flash pattern while preserving face up color. The generous table and carefully proportioned crown height work together to present an even lively yellow across the table, while the pavilion facet angles are calibrated to maximize internal reflection rather than leakage, which is particularly important for yellow sapphires where controlled light return enhances perceived intensity without over darkening the stone. The gem has been evaluated as very slightly included at eye level, indicating inclusions that are present but minimal in both size and contrast, they do not interfere with transparency or light performance and do not compromise structural integrity. The polish is graded excellent, reflecting meticulous lapidary finishing with crisp facet junctions and smooth facet planes, and the stone has undergone standard heat treatment to stabilize and intensify its yellow saturation, a stable and widely accepted enhancement that optimizes the gem for enduring beauty.

From a color and historical comparison perspective this sapphire occupies a notable place among famous yellow gemstones, offering intense color intensity that invites comparison to the renowned Tiffany Yellow Diamond in terms of visual presence, while remaining fundamentally different in optical character due to sapphire having a lower dispersion but higher durability. Unlike the Tiffany Diamond which displays pronounced fire and is a diamond class optical performer, this yellow sapphire exhibits a warmer, more saturated chroma that reads as a pure golden to classic yellow under daylight and strong incandescent lighting, attributes highly prized in yellow sapphire connoisseurship. When contrasted with historic blue sapphires such as the Star of India or the Logan Sapphire, this stone demonstrates the alternative spectrum of value within the corundum family, where rare, intense yellow saturation is less commonly seen and therefore offers a distinct collectible appeal. The Madagascar provenance contributes to the gemological story, as Malagasy sapphires are known for their varied and saturated color range, and the crystalline growth conditions there often yield clean crystals capable of receiving high quality cuts. The combination of eye level very slightly included clarity, intense color intensity, and the precision radiant cut gives this gem a unique proposition, it delivers the warmth and presence of notable yellow gems from history with the day to day practicality and wearability of corundum.

For placement and setting the stone’s dimensions and optical behavior recommend design choices that enhance face up color and scintillation, a slim bezel will emphasize shape and protect the trimmed corners, while a halo of well matched melee, or a micro pave shoulder, will amplify perceived size and increase contrast for a more brilliant presentation. For maximum color contrast set in yellow gold to intensify warm undertones, set in white metals such as platinum or white gold to create a modern icy contrast that emphasizes clarity and scintillation, or use a mixed metal approach to balance both effects. From a durability standpoint sapphire rates nine on the Mohs scale, suitable for everyday wear in engagement jewelry with appropriate protective settings. At The Natural Sapphire Company we assess every stone using calibrated lighting, high magnification inspection, and precise measurements to ensure accurate reporting of proportions, clarity, and finish. We can provide independent laboratory grading upon request and advise on matching and mounting strategies to preserve the integrity of the heat treated sapphire and to showcase its intense yellow hue to best effect. This 1.54 carat radiant yellow sapphire from Madagascar represents a synthesis of technical cutting excellence and rare color, a stone that references the grandeur of historic yellow gems while offering practical superiority for contemporary use and custom design.
