The absence of lab reports regarding gemstones poses challenges in identifying their natural or synthetic origins and key properties conclusively. This reliance on subjective assessments means that without such reports, definitive conclusions about gemstones are elusive. Even expert opinions lack conclusiveness when the necessary laboratory documentation is absent. - This meticulously crafted ring has been meticulously preserved in its original condition, without any modifications. Please note that gemstones are often subject to treatments aimed at enhancing colour and clarity; however, such treatments have not been assessed for this specific item. - The shipping charges encompass the cost of packaging, the item's protective box, and unforeseen expenses. - Customs and import duties are the sole responsibility of the purchaser. - In the event of an order cancellation, all associated costs will be borne by the buyer.
