Chaton (Round) Rhinestones: Sizes are typically expressed in "Stone Size" or "Pearl Plate". For example, a 30ss (round chaton) is .256 inches or 6.5mm (about 1/4 inch in diameter) and equivalent carat weight (in diamond) is 1 carat.

Fancy Stones: Sizes are typically expressed in Millimeters (mm). There are about 25mm to an inch so for example a 12/8mm oval stone Is about 1/2 inch long and about 1/3 inch wide.

The stone size measurement represents the longest and widest point of the stone

Typically fancy stone sizes are expressed with the length first, then the width (12/8mm), however will also see the size expressed with the width first (8/12mm). These stone sizes 12/8mm and 8/12mm are the same size, just expressed differently.

Vintage items will say Vintage, Genuine Vintage or Old in the item title and item details.

My new, hand oxidized items will say Vintage Style (or Sty) in the title and item details.

My new, hand oxidized items are all genuine brass (naturally nickel and lead free) and Made in the USA.
Many sizes are stated in mm (or millimeters).

There are approximately 25mm to 1 inch.

So a size of 25x18mm would be about 1 inch by just under 3/4 inch.

Swarovski crystals and chaton (round) stones are stated in ss (stone size) or pp (pearl plate).

Sheet metal and wire is measured in gauge size and is usually shown as a number followed by g (for example 22g sheet metal).

Visit my shop DIY Kits | Tutorials category for charts that convert the above measurements to inches, millimeters, and carats.
Most of my hand oxidized pieces have a natural (matte and unsealed) patina. Some items have been coated with a protective sealant (especially hand oxidized chain).

Naturally occurring patina are items that have a patina that has developed on it's own over the years.

Please see item details to determine whether the item is hand oxidized with natural patina, if the patina has been sealed, or whether it is naturally occurring patina.
