Stamped "pt900 Emerald 0.74 Diamond 0.48". The emerald is approximately 5mm square. I believe it's size 14. I received it from my mother, but it doesn't fit me... I'd like to sell it to someone who will wear it. It's a natural emerald, so it has inclusions, but the color is beautiful and not pale. There is a slightly white area near the surface, possibly an inclusion. It has been cleaned at a jewelry store, but it is a used item, so there may be some minor scratches or scuffs. Please understand this before purchasing. Please refrain from purchasing if you are looking for a perfect item or are very sensitive to details. Returns are not accepted due to the fear of item substitution. Please ask any questions before purchasing. There is no certificate of authenticity. The case in the photo is not included. It will be shipped in a different case. No claims, no returns. Thank you.
