I just got these opal studs in the mail. They're my mother's day gift and I ordered them early just in case they didn't have enough fire to them so I could return them and still have time to find another pair. I usually like to get natural gemstones if I can but natural opals can sometimes be a hit or miss.
These 8mm synthetic opals look amazing. The light doesn't even have to hit them for the fire to show. I love that they come in yellow gold and I didn't have to spend $100 for them. The backing's seem to be fine and I doubt I'll have to replace them.
This is exactly what I was looking for. The original pair I was looking at round up to $150. I'm so glad I found these.
