Please read the item description for size information. All stone dimensions are included. IF I have accidentally failed to include stone dimension please do me the favor of asking via eBay message. Sometimes I do make mistakes and appreciate errors being brought to my attention so that I can correct them. In stone dimensions, most times I take photos of the items in my hands as a size reference. I have very large hands so the earrings will actually look smaller in my hands. I have tiny wrists (6.25") so bracelets will look larger. I always advise my customers to have a ruler near their computer when jewelry shopping online. I give stone dimensions in the metric system (mm) and lengths in standard (inches).
If you would like to upgrade to sterling silver leverbacks, threaders, etc. inquire via eBay message prior to bidding or purchase. I will be happy to update this listing to reflect the customizations you need. Some upgrades do involve 'add on charges' to cover additional supply costs.
