0.42 ct Natural Unheated Violet Sapphire – Trillion (Trilliant) Cut | AGCL Certified | Sri Lanka (Ceylon)

A natural 0.42 carat violet sapphire in a trillion (trilliant) cut, completely unheated, documented on AGCL Report #M262743. The trillion is an equal-sided triangular shape that creates a larger face-up appearance than oval or round equivalents of the same weight, and in violet sapphire, the three-sided outline creates a striking geometric accent. At 0.42 carats, this stone is well-sized for earring accent positions, three-stone ring side stones, and small pendant designs where the trillion's distinctive outline adds visual character.

Rarity Analysis

Violet sits well outside the blue, pink, and yellow sapphire that make up most commercial supply, and pairing it with a trillion cut and unheated status narrows the field further.

• Color: Violet — a true blend of blue and red hues in corundum — is uncommon in commercial supply and is frequently the product of heat treatment shifting purple or gray material; natural violet is a smaller subset still.
• Size: At 0.42 ct, this stone sits at the lower end of the range typically cut for violet sapphire, where material is most often found and faceted under 1 carat.
• Treatment: Most commercial sapphire, and most violet sapphire specifically, is heat-treated; this stone carries a "No Indication of Heating" finding on AGCL Report #M262743.
• Cut: The trillion is rarely used for violet sapphire, which is more commonly faceted as round or oval; a well-cut trillion at this weight is a distinctive combination in its own right.
• Documentation: AGCL Report #M262743 independently confirms the stone as natural corundum, its weight, dimensions, and no indication of heating; origin is the store's own assessment and is not addressed by the lab report.
• Combined effect: The trillion cut, natural violet color, and unheated status together make this a harder stone to find a direct substitute for than any single characteristic would suggest.

Buying Guidance

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

• Check the pointed corners in person or on video. Trillion cuts have three vulnerable corners — ask to see close-up video of the culet area before committing.
• Plan a protective setting. At 4.50 x 4.46 x 2.85 mm, this trillion suits prong or bezel settings with corner protection for ring use, or a secure bail for pendant use.
• Ask for the underlying lab report, not a summary. AGCL Report #M262743 documents this stone's treatment status independently — request it when comparison-shopping.
• Weigh the cut against availability. Trillion-cut violet sapphire in unheated quality is uncommon; this stone's combination of shape, color, and treatment status is not easily replaced at this weight.
• Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.

Why Choose this 0.42 ct Unheated Trillion Violet Sapphire?

Trillion-cut violet sapphire in unheated quality at this weight combines three uncommon characteristics: a geometric cut rarely used for violet material, a natural color that heat treatment typically destroys, and a sub-half-carat scale that makes it practical for accent and earring applications.
