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.

Good to Know

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.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
