Have You Been Wondering How to Grade Sea or Beach Glass?

Here you will find an explanation of important features in real beach glass and a 5-grade quality scale, including jewelry grades and craft grades of glass.

Grade Sea Glass?

Grade Sea Glass
Yep! To establish the value of a piece of sea glass, you need to evaluate the grade (physical appearance) and the color rarity.   

Here we'll be talking about how to grade your beach glass.

To evaluate the color rarity of your pieces, click here.

The two main divisions are Jewelry and Craft Grade sea glass.These are broken down into a total of 5 categories:

1.  Jewelry

2.  Craft




Jewelry Grades of Sea Glass

Jewelry Grade A

  • Evenly and thoroughly frosted with very rounded corners. 
  • No chips, poorly-rounded corners, or visible defects.
  • Excellent for fine jewelry.
Here are two views of the same numbered pieces from two different sides. Notice the features.
View 1 - Jewelry Grade AJewelry grade sea glass View 2 - Jewelry Grade AJewelry Grade A Sea Glass
1. Cobalt blue
2. Brown
3. Teal
4. Turquoise
5. Pale sea green (seafoam)
6. Dark aqua
7. Light cyan
You will notice that pieces #2, #6, and #8 have some edges not quite as rounded.

If they were a little sharper, they would fall into a Jewelry B grade.

(For color ID see the Sea Glass Color Chart)

Jewelry Grade B

  • Same qualities as A grade sea glass but
  • with a small chip or defect visible from one side only OR
  • more defined edges/corners.
  • Very good for jewelry and arts.   

Jewelry Grade B
Jewelry grade B sea glass

You will notice here that #1 and #4 have obvious chips.

However they are the only defects and are visible from one side only, and so qualify as Jewelry Grade B.

Pieces #2, #3, and #5 don't have any visible chips.
  1. Aqua
  2. Green
  3. Brown
  4. Cobalt Blue
  5. Medium sea green
However, the edges are a little too defined to be Jewelry Grade A.


(For color ID see the Sea Glass Color Chart)

Jewelry Other

We haven't included a picture here, as the pieces do vary.  They may have
  • more than one of the defects of B grade, but
  • because of unique shape, color, or other qualities, it could make a nice jewelry piece.


Craft Grade Sea Glass

Craft Grade A Sea Glass

Craft Grade A

  • Evenly and thoroughly frosted but 
  • with chips or defects visible from both sides or
  • distinct angular edges and
  • not more than 1 rough or cracked edge.
Good for many art and craft projects.

Craft Grade A Sea Glass

Craft Grade B

  • Somewhat frosted.
  • May have chips, defects, more than 1 rough edge.
  • Good for mosaics and some craft projects.
  

Pet Clothing
Craft Grade Mixed Craft grade sea glass

Craft Grade Mixed

  • Somewhat frosted.
  • May have chips, defects, more than 1 rough edge.
  • Good for mosaics and some craft projects.
You can see that this mix of Craft Grade A and B sea glass is much less rounded and tumbled.
1. Cobalt blue 
2. Pale sea green
3. Off white (clear) Craft A
4. Light cyan
5. Misty Rose
6. Pale turquoise
7. Green
8. Dark olive
Pieces #1 and #2 are Craft Grade B.

Pieces #3 and #4 are Craft Grade A, being fairly well tumbled and smoothed but with distinct edges and some chips.

Pieces #6, #7, and #8 are actually somewhat shiny. Along with piece #5, they barely meet the standards to be considered sea glass.

However, the colors are not so common so might be kept in a collection until replaced with similar colors that are in better tumbled condition.

(From Sea Glass Color Chart)

Note: Grading sea glass is not an exact science as there is much individuality to each piece. The Grade Chart above contains the main points you'd look for when buying or selling (or deciding it's a keeper or throwing it back for more punishment). 

I might mention that Lin makes beautiful wrapped jewelry and has sometimes used a Craft Grade A shard because of uniqueness, color, and able to mask the defects sufficiently!  She also loves white, a very common color, because it goes with everything...use your judgment, and, MOST OF ALL, ENJOY!!

Thanks!!

" Hi Lin and David,

I have come to sea glass via my shell collecting and am finding it very addictive too. Last year I found a glass bottle stopper which was a thrill.

Very small and few people but a nice supply of glass just as you stated.

I really enjoy the newsletter and can easily spend an evening getting lost in the stories and comments."

Regards,

"


Anne Cram

" Just wanted to thank you for all of your helpful information.

The sea glass community is filled with people who guard their "secret beaches" so it is refreshing to see that there are people who are willing to share.

It's so useful for those of us that don't live near a beach and travel to find our glass.

The information posted here lets us spend more time enjoying our adventure rather than wasting time looking for a great spot

Thanks again,

"
