I wonder if there is a market for antique jewelry, maybe a piece that would have considerable value as a collector piece/antique? Maybe the ring of some famous Duchess or something. Where can one find out about these auctions/dealers? I'm thinking that something with real provenance could be interesting.

Good thread.

The day you lose money on it is the day you walk out the door with it.

You can get antique jewelry at estate sales or antique shops. The better option is to get a ring in a vintage style. You can go custom or look around because the antique styles are back in vogue.

Synthetic sapphires also differ from natural sapphires in some mechanical behaviors. From what I understand, natural sapphire crystal nucleation and growth happens in a way that promotes isotropy, while the rapid nucleation and growth methods of synthetic sapphires promotes anisotropy.

One can see the cause of this very easily under a high power microscope, synthetic sapphires have parallel curved growth grains. At the inflection of point of the stria, the sapphire crystal layers are very prone to flaking and chipping due to shearing stresses (but not normal stresses). This happens especially in high end watches with sapphire crystals, the rim of the crystal (where it meets the bezel) will often be chipped. Natural sapphires lack these defined growth lines, and hence crack propagation via these grain boundaries will not happen as readily.

In other words, synthetic sapphires have weaknesses at certain points when impacted by force vectors in specific directions due to the manufacturing process being uniform and predictable.

I believe all girls admire celebrities more or less. So how about choosing a ring from celebrity engagement rings. First you should know which star she loves most and then buy her a ring look like that of the stars.
