This product is a 0.5ct moissanite ring set in 925 sterling silver, perfect for engagement, wedding, or anniversary occasions. The white moissanite stone is round in shape and has excellent cut grade, making it a beautiful and eye-catching piece. The ring is nickel-free and handmade with a lab-created main stone, ensuring quality and durability. It comes with a COA and warranty from the seller, making it a reliable and valuable purchase. Personalization is available for a custom touch, and the ring is resizable for a comfortable fit. I picked this up at auction and obviously dont know much about jewelry to be honest. Make anoffer.
