Posh will authenticate any sale over $500. Your jeweler can also confirm for you. Center stone approx 1-1.15 ct Trillion cut natural earth mined sapphire. May be larger because I can’t get an accurate mm due to metal covering certain areas of stone. Approx. 11-12 baguettes also real sapphires. 5 small channel set diamonds. Depth of stone is 5mm. Weight 4.3gm Size 6.5 This vivid blue sapphire fooled me! Thought it was a real tanzanite because of how it can give off different colors. But, it’s just a really good read sapphire and some blue sapphire’s are color changing in light. Images taken in natural & evening light. 1 photo I held a LED light to the stone. Had fun with this cool stone and color changes 🥰 Preowned. Reach out if you have any questions. Shipped with insurance
