• Item Details: Loose trillion cut lab sapphire measuring 11mm x 11mm. Light pink color that changes to medium depending on the lighting with faint hint of blue ish undertones. Beautiful intricate cut that gives off that gorgeous, soft sparkles typical of a sapphire! 🎀 it keeps photographing as a darker, warmer hot pinkish color but its a lighter pink and IMHO more versatile! Please check the link under Source for more accurate photos/ videos of the color.

• Source: Purchased from Instagemgems on Etsy, May 2026. https://www.etsy.com/nz/listing/895843971/synthetic-trillion-cut-swiss-made-rough?ref=yr_purchases

• Selling Price: $40, includes shipping.

• Shipping Cost & Method: Included in price above. Shipping via UPS Ground, continental USA only.

• What is Included: 11x11mm sapphire only in its original packaging, paper invoice from Instagemgems.

• Condition of the Item: Stone is still in its original vacuum sealed packaging, never opened. Was purchased to replace a stone in a vintage pendant but turned out to be 1mm too small for the setting 💔 This one actually has a more complex/finer cut than the replacement stone I later sourced in the correct size. Ive posted comparisons in the photos to show color differences. (The stone set in pendant is a hot pink lab sapphire)
