Vintage Diamond Cuts

Before diamond cutting machinery that emerged in the early 20th century, diamonds were often cut by hand, using techniques that are not used so frequently today. These vintage cuts resulted in diamonds that possessed shapes, facet structures and dimensions that captured the design trends of their eras. While diamonds cut in these ways often emit less brilliance and fire than modern cuts, they do exude a more subtle and romantic glow. Vintage cut diamonds have risen in popularity over recent years due to their desirable delicate and gentle look.

Estimating the age of antique bottles can sometimes be a difficult task even for the experienced collector. However, by following some basic guidelines anyone can determine approximate age. Although this brief article is primarily intended for American-made bottles, glass from other countries has evolved similarly. This outline covers basic patterns but note that there are exceptions to every rule.

Most bottles produced in the past years were formed by blowing molten glass into a mold. Molds were made of iron or wood and consist of 2 or 3 pieces. When the bottle was removed from a mold, a faint seam remained in the glass, running from the base to a point somewhere between the shoulder on up to the top edge of the mouth. In a 3-piece mold, a seam often runs horizontally around the shoulder of the bottle with opposing seams on the neck.
