1.59 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This is a transparent 1.59 carat radiant shape yellow sapphire from Ceylon Sri Lanka, a stone that stands out immediately for its weight and presence. The dimensions of 7.56 x 5.81 x 4.07 mm give it a substantial face up size while maintaining comfortable proportions for rings, pendants, and bespoke pieces. The radiant cut has been executed to balance brilliance and color, and the excellent polish ensures crisp facet junctions and lively light return. Clarity is graded as very slightly included when evaluated at eye level, which means the inclusions do not interfere with the gem forward appearance, and instead support a lively, clean window to the vivid yellow hue. The vivid color intensity is a defining attribute, and while the sapphire has undergone beryllium diffusion, the result is a saturated, even yellow that reads as natural to the eye, with stable color distribution across the pavilion and crown.

Weight matters in colored gemstones in ways that go beyond size alone, and this 1.59 carat yellow sapphire exemplifies why. In the marketplace many yellow sapphires are offered in smaller weights, often under one carat, where individual color and clarity can seem less impressive because the value equation is dominated by availability. Larger yellow sapphires with vivid color and good clarity are comparatively scarce, particularly from Ceylon which is known for producing lively, saturated tones. A 1.59 carat stone crosses a perceptual threshold, where the face up presence becomes unmistakable in a variety of settings, and where the per carat price typically increases because collectors and designers prize both the visual impact and the comparative rarity. When you compare this stone to smaller or lower weight alternatives, the difference is tangible in photographs and in person, and the long term retention of value tends to favor stones that combine size and desirable color.

Comparing this sapphire to other market options highlights its unique position for quality and value. There are untreated Ceylon stones that command premium prices for certain collectors, and there are lighter stones that cost less but offer diminished presence. There are also heated stones and synthetics, which can offer appealing color at lower cost, but do not provide the same natural origin narrative or resale dynamics that collectors consider. The beryllium diffusion treatment on this sapphire should be disclosed and understood, it is a stable enhancement that creates vivid, evenly distributed color and allows a more affordable purchase price compared to an untreated stone of similar hue and weight. For many buyers the result is an optimal balance of eye catching color, strong face up size at 1.59 carat, and overall value, especially when compared to competitive yellow sapphires that are either much smaller, less vivid, or produced by synthetic processes. The clarity grade of very slightly included at eye level is another differentiator versus many commercial grade stones which can show more obvious inclusions, and the excellent polish elevates the gem above many mass market options where finish is compromised.

The Natural Sapphire Company presents this radiant shape 1.59 carat yellow sapphire as a rare opportunity to acquire a boldly colored Ceylon gem with impressive face up impact and responsible disclosure of treatment. For customers seeking a centerpiece for a bespoke engagement ring, a striking pendant, or a pair of matched pieces, the weight and dimensions of this stone provide design flexibility and an unmistakable focal point. From a practical perspective the stone sits well in solitaire and halo settings, and in modern geometric mounts that emphasize the radiant outline, while the vivid color reads beautifully against platinum and yellow gold alike. When you compare the total package to similar listings on the market, this sapphire offers a superior combination of carat weight, color intensity, clarity at eye level, and finish, making it a wise choice for buyers who want something beyond the ordinary.
