Sea Glass Rarity Guide

Sea Glass Value & Rarity

Sea glass value and rarity are largely dependent on color.    However, rarity varies via location.  For example, I found an abundance of black glass in Florida, as it originates from shipwrecks and trading in the Bahamas.  A collector at any other shore may find black glass more difficult to find, hence more rare.

A Typical Guide to Sea Glass Rarity from Common to Unique

Green glass– Mostly comes from beer bottles.  Heineken, Rolling Rock, wine and soda bottles.  Roughly 2 in 10 pieces of sea glass will be green.

Brown Glass–  New and old mostly from beer and liquor bottles 3- 4 in 10 pieces will be brown.

White or Clear Glass– Has numerous sources. Soda bottles, liquor bottles, panes of glass and some reinforced safety glass. 4 in 10 pieces will be white or clear.

Sea foam Green– Mostly old original coke bottles. 5 in 10 pieces will be sea foam green.

Cobalt Blue– Originates from Noxzema bottles, Milk of Magnesia, Vix  Vapor Rub, medicine bottles and poison bottles.  1 in 200 to 300 pieces will be cobalt blue.

(On Palm Beach Island this color was extremely rare, I found 2 jewelry grade pieces in 3 years).

Light Blue/Cornflower Blue-  Originates from bottles made right before printed labels were invented.  Light blue and cornflower blue glass were once apothecary jars and the first source of embossed glass. 1 in 500 to 700 pieces will be light blue or cornflower blue.

Lime Green or Chartreuse Glass– The major source is lemon lime soda bottles from the mid 1900’s. 1 in 500 pieces of glass found will be lime green.

Teal or Turquoise- The source of this color glass is generally seltzer bottles from the early 1900’s; possibly inkwells from roughly the same time period.  Other sources include insulator glass used on electric polls.  1 in 3000 pieces of glass will be teal or turquoise.

Black/Purple- Very old late 1800’s wine bottles.  Strangely buttons are also a source.  Black sea glass is actually olive when held up to bright light. 1 in 3000 to 4000 will be black or purple.

Yellow-  The fourth rarest color of sea glass, generally from headlights of old cars.  1 in 4000 pieces of glass will be yellow.

Pink/Lavender/Peach-  These colors of sea glass are referred to collectively as depression glass as they are from the depression era in the 1800’s.  These pieces appear white when collected under the bright sun on the beach.  However, when placed against a white surface their pale beautiful shades appear.  1 in 3000 to 4000 will be depression glass.
