Problems solved by technology

However, cut evaluation using only this loupe, while possible for experts with advanced skills, is not possible for the average consumer
In particular, in the round brilliant cut, which is graded with strict standards, it is difficult even for experts with advanced skills to make reliable evaluations.

Embodiment Construction

[0038] Hereinafter, a preferred embodiment of the present invention shown in the drawings will be described in detail. The technical scope of the present invention is not limited to the embodiments shown in the drawings, and can be appropriately changed within the scope described in the claims.

[0039] A gemstone observation instrument according to an embodiment of the present invention includes a main body 1 having a magnifying lens 12 and a cylinder 2 connected to the main body 1. The main body 1 is connected to one end side of the cylinder 2, and the observation object D is arranged in the cylinder. The other end side of body 2 (refer to figure 1 and figure 2 ).

[0040] As the observation object D, a cut diamond was exemplified, but it is not limited to this, and the gem observation tool of the present invention can be used as long as it has a cut surface and has transparency.

[0041] also, figure 2 The illustrated loose stone case R is a case for accommodating th...

Abstract

The present invention addresses the problem of providing observation equipment for jewels that is capable of observing the luminance and flaws in jewels as well as a pattern appearing in a reflective image of the jewels. The observation equipment is for observing a transparent jewel with a cut surface and is characterized in that: the observation equipment comprises a main body part 1 having a magnifying lens 12, and a tube body 2 connected to the main body part 1; the tube body 2 includes a transparent tube body 21 that allows natural light to pass through, and a light-shielding member 22 that shields natural light; and the light-shielding member 22 is configured to be movable along the axial direction of the transparent tube body 21.

Description

technical field [0001] The present invention relates to an observation tool and an observation method for cut diamonds and other gemstones having cut surfaces and transparency. Background technique [0002] Generally, the value of cut diamonds and other gemstones with facets and transparency is ranked by evaluating the four elements of color (color), clarity (clarity), carat (weight) and cut (polish) (below called classification). Among them, since the cut determines the direction of the surface reflection and internal reflection of the light incident on the gemstone, it is an important factor in determining the brightness of the gemstone, which greatly affects the final beauty and value of the gemstone. [0003] However, the evaluation of cut is the most complicated evaluation among the above four elements, and it is technically very difficult. Historically, the state of cut applied to gemstones has been visually identified using a magnifying glass. However, cut evaluati...
