Estimating gemstone weight in mounted settings

A method comprising:

• reflecting light onto a structure;
• obtaining one or more images of the structure;
• and
• generating weight information of the structure using the one or more images, wherein one of the one or more images is an angular spectrum image of the structure, and wherein the generating of the weight information involves comparing the angular spectrum image to other angular spectrum images of other structures.

A system comprising:

• a structure imaging assembly, wherein the structure imaging assembly comprises an image sensor and a holder;
• a structure image analyzer, wherein the structure image analyzer receives image data obtained by the image sensor and determines weight information of a structure using the image data;
• a support frame;
• and
• at least one support rod attached to the image sensor, wherein the at least one support rod slides along the support frame.

A system comprising:

• a structure imaging assembly, wherein the structure imaging assembly comprises an image sensor and a holder;
• a structure image analyzer, wherein the structure image analyzer receives image data obtained by the image sensor and determines weight information of a structure using the image data;
• and
• a cover having an inner surface, an outer surface, and an aperture, wherein the cover covers the holder, wherein the inner surface of the cover has a first color feature, a second color feature, and a third color feature, and wherein each of the color features is a strip of colored material that extends in a circular fashion along the inner surface of the cover.
