This specific item
The three formats of this product cover complementary shapes: the 47×25 mm is an elongated oval, ideal for a large vertical pendant; the 42×21 mm is a more slender oval for a pendant or statement ring; the 25×28 mm is
Thickness varies: 4 mm for the 47×25 (thicker, more resistant to standard bezels) and 3 mm for the other two (require a thinner bezel sheet, 0.6–0.8 mm, so as not to exceed the stone's height). All have perfectly flat backs.
How moss agate inclusions are formed
Moss agate originates in India, mainly in the hydrothermal deposits of Gujarat and Rajasthan states. The base chalcedony crystallizes in cavities of volcanic basalt from silica-rich solutions.
What setting it works for
-
Pendant with 925 silver bezel — The green of moss agate and the white of silver form a classic combination in botanical jewelry. An 0.8 mm bezel works for all three formats; for the 47×25 mm, an integrated bail or soldered bail is recommended due to the weight of the piece.
-
Statement ring with medium format (42×21 mm) — The oval shape with a 2:1 aspect ratio is the most common for large stone rings. The 3 mm thickness keeps the profile low and makes it more comfortable to wear.
-
Rectangular brooch (25×28 mm) — The almost square format is most suitable for brooches or as a central piece of a multi-element necklace; the geometric shape contrasts well with the organic pattern of the inclusions.
Moss agate in lapidary tradition
India has historically been the main global supplier of moss agate to the European lapidary market, with active trade since the 17th century through the routes of the East India Company.
In crystal tradition, moss agate is associated with prosperity, connection to the earth, and constant growth. It is considered the stone of long-term projects and of those who work with their hands.
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
How to recognize genuine moss agate
Genuine moss agate has areas of varying density of green inclusions — variation is natural and inevitable. An imitation in colored green glass is too homogeneous.
Frequently asked questions
Is the green color natural or dyed?
No detectable treatment. The green comes from natural chlorite inclusions precipitated within the agate. Statement based on lapidary observation; items do not include gemological certification.
How do I choose between the 3 formats?
The 47×25 mm is the largest and most striking; ideal for a focal pendant. The 42×21 mm is the most slender; works as a pendant or statement ring. The 25×28 mm is the most compact; good for a brooch or secondary pendant in a set.
What are the exact dimensions of each format?
Nominal: 47×25×4 mm, 42×21×3 mm, and 25×28×3 mm. Tolerance ±0.5 mm in any dimension.
Is each variant in stock?
The 47×25 mm variant is currently out of stock. The 42×21 mm and 25×28 mm variants are in stock. The inclusion pattern is distinct in each piece.
What sheet thickness do you recommend for the bezel?
For the 47×25×4 mm: 0.8–1.0 mm sheet. For the 3 mm thick ones: 0.6–0.8 mm to not exceed the dome's height. In all cases, we recommend a closed bezel setting.
How do I care for them?
Warm water, mild soap, dry thoroughly. More details in the jewelry and mineral care guide.
