What does the 925 stamp mean?

Short answer: Yes, I have had mine for two years and it still looks great. Just clean it regularly with soap and water.

Here is my honest take after owning one.

What My Jeweler Said

My bench jeweler told me the main thing people regret is skimping on the setting. The stone itself is fine, but a weak prong will let it fall out. Spend a bit more on a solid setting.

Bottom Line

Yes, it is worth it for most people. Just buy from a known seller and inspect the prongs every six months.

Based on my experience: I bought mine from Charles & Colvard for about $8,000. This is totally normal. Mine did the same thing for the first month then settled.

Not worth the risk in my experience. Spend a little more and buy from a real store.
