1.07 ct Natural Unheated Yellow Sapphire – Round Cut

A natural 1.07 carat round yellow sapphire, completely unheated, with an AGCL Gemstone Report (#M263989) confirming species, weight, dimensions, and unheated status. Yellow sapphire in a round cut at just above 1 carat represents the most practical center stone specification for buyers who want a yellow sapphire in the most standard ring and pendant format. The round flower-faceted cut returns strong light, making the yellow vivid and active under all lighting conditions. Unheated status confirms the color is entirely natural with no thermal enhancement.

Rarity Analysis

A few factors combine to make this particular stone less common than a typical yellow sapphire of similar size:

• Color: Pale-to-medium yellow saturation, entirely natural — most yellow sapphire reaching this clarity and evenness of color on the market has been heat-treated.
• Size: 1.07 ct crosses the practical threshold most buyers need for a standalone center stone rather than an accent.
• Treatment: Unheated, confirmed by AGCL report #M263989 — unheated yellow sapphire over 1 ct is meaningfully scarcer than heated material of the same size.
• Cut: Round flower cut, a brilliant-style faceting pattern chosen to maximize light return in a lighter-toned stone.
• Documentation: AGCL Gemstone Report #M263989 confirms species, weight, dimensions, and unheated status.
• Combined effect: unheated status, over-1-carat weight, and a round brilliant-style cut rarely come together in the same yellow sapphire, which is what sets this stone apart from typical market supply.

Buying Guidance

A few practical points to weigh before purchasing this specific stone:

• Compare saturation in person: pale yellow sapphires can photograph differently depending on lighting; use the Try On option to see it under your own conditions before committing.
• Setting choice matters: the round flower cut pairs well with prong or halo settings that let light enter from the sides and boost apparent color.
• Jyotish buyers: confirm with your astrologer that 1.07 ct and unheated status meet your specific Pukhraj requirements before purchase.
• Budget check: unheated yellow sapphires above 1 ct carry a price premium over heated stones of comparable size and color — factor this into your comparison shopping.
• Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.

The round flower cut in yellow sapphire produces strong brilliance and a vivid yellow display in any standard solitaire, halo, or three-stone setting.
