10. Gemstone Clarity Levels Level Characteristics IF Completely Flawless VVS A very, very small flaw that is not easy to see even with a 10x magnifying glass. VS A very small flaw that can be observed with a 10x magnifying glass. SI A flaw visible to the naked eye that has affected the appearance. I Not suitable for wearing, but suitable for specimens Rubies with a flaw grade of SI have patches of feathery cracks visible to the naked eye. Sapphires with a flaw grade of SI have feathery cracks visible to the naked eye.

11. 04 The quality of gem cutting

12. The quality of gem cutting Diagram of the diamond-cutting structure The quality of gem cutting is determined by the strength of the fire, with a well-cut gemstone having more vital fire, and personal preference plays a significant role in choosing the cut shape.

15. Optimization treatment Rubies treated with beryllium exhibit different shades and are vividly colored but are relatively inexpensive, so consumers should pay particular attention before purchasing Ruby filled with glass to fill cracks If the surface of the jade has yellow jade skin, it can be heated with a hydrogen-oxygen flame to turn the jade skin red. Some unscrupulous merchants will sell it as blood jade. Upon careful observation, the surface of the fire-roasted jade skin will have fine cracks.

17. 06 Be careful when buying jewelry when traveling

18. Be careful when buying jewelry when traveling Synthesized rubies Synthetic sapphire When traveling, the most commonly bought items are these clear synthetic red and blue sapphires (synthetic corundum). Natural red and blue sapphires usually have some inclusions. If the red and blue sapphire is very clean and the price is not high [US$93-156, you should be cautious about whether synthetic. Beware of low-cost group tours that may involve mandatory shopping for substandard gemstones; verify the authenticity and quality of jewelry before purchasing, especially in foreign countries.

19. 07 Afraid of being scammed, is having a certificate enough?

20. How do you interpret a GIA diamond certificate? (1) Date Submission for appraisal time. (2) Laser Inscription Registry appraisal number laser inscription number engraved on the diamond’s girdle. (3)Shape and Cutting Style records the cutting shape or style of the diamond, for example, Round Brilliant. Other cutting styles (such as heart shape, pear shape, princess cut, etc.) are called fancy cuts. (4)Measurements diameter and depth The diameter is calculated by multiplying the minimum diameter by the maximum and height. Unit: mm. (5)Carat Weight The weight of the diamond in its raw form is measured in carats. Usually calculated to the second decimal place. 6 Color Grade (6) Color grading. The color grades range from grade D to grade Z. (7)Clarity Grade The identification results of diamond clarity. It is divided into FL (Flawless), IF (Internally Flawless), VVS (Very Slightly Included), VS (Very Slightly Included), SI (Slightly Included), and I (Included). (8)Cut Grade Cut grades include Excellent, Very Good, Good, Fair, and Poor.

21. How do you interpret a GIA diamond certificate? (9)Finish Polish They divided into five grades: Excellent, Very Good, Good, Fair, and Poor. Usually, the polishing grade of diamonds is around Good; very Good is generally considered better polishing, and Excellent is regarded as the best polishing. Symmetry The quality of the cut also depends on whether the overall symmetry of the diamond is complete, whether the diamond is rounded, whether the table and the pointed bottom are off-center, whether the left and right sides of the table are symmetrical, and whether each adjacent edge line meets at a point. Each small facet must also be symmetrical up and down, left and right, which indicates A-grade cut. The grading is the same as polishing and divided into five levels. (10)Fluorescence The presence or absence of fluorescence under long-wave ultraviolet light can be categorized into four levels: None, Faint, Medium, and Strong. The strong blue fluorescence reaction of natural diamonds can make the diamond appear whiter; if there is no fluorescence, it indicates that the diamond is inherently very white, and if the conditions are good, the price will be slightly higher. (11)Comments Additional notes on diamond characteristics or other phenomena. (12)REFERENCE DIAGRAMS Flaw symbol illustrations Use some graphical symbols to indicate where the diamond has flaws, along with annotations explaining what type of flaw the illustration refers to. (13)COLOR SCALE, CLARITY SCALE, CUT SCALE Display the relevant positions of the diamond’s color, clarity, and cut in the GIA grading system. (14)Profile to actual proportions Display the percentage data of the proportions and angles of all parts of the diamond.

22. 08 Introduction to Basic Tool Usage

23. Introduction to Basic Tool Usage (1) Eight Hearts and Eight Arrows Viewer (2) Pen Light (3) 10x Loupe (4) Tweezers (5) Diamond Probe

24. Introduction to Basic Tool Usage (1) Place the gemstone face down, aligning the gemstone with the front edge of the clamp. (2) Hold the gemstone, ensuring it does not extend beyond the end of the clamp. Hold the clamp with your hand positioned slightly lower in the middle. (3) Hold the magnifying glass, placing your index finger inside it and securing it with your thumb and middle finger. (4) Move the gemstone under the magnifying glass for observation (between the middle finger and ring finger). The magnifying glass should be parallel to the clamp and not extend beyond the top of the magnifying glass. (5) Bring the gem close to your eyes, with your thumb pressed against your cheek. Look straight ahead, keeping your eyes as wide open as possible. If you are not used to it, you can close one eye. First, observe the front of the gem to see if there are any inclusions, whether the surface polishing is bright, and if there is any wear on the cutting surface. After observing the front, continue to observe the back of the gem. While observing, move the gem back and forth to adjust the focus until it is the clearest.

25. How to measure the refractive index of a gemstone? (1) Drip by drip in the refractometer 2-3 millimeters of refractive liquid. (2) Place the faceted gemstone with the table facing down on the glass. The cabochon or opaque gemstone should have the convex side facing down. (3) Turn on the light source and close the lid. (4) Bring your eyes close to the refractometer and observe the refractive index of the gemstone. Use the near measurement method for faceted gemstones and the far measurement method (about 25-30 centimeters from the eyepiece) for cabochon gemstones.

26. Demonstration of various instrument operations Observe whether the gemstone has birefringence using a polarizing filter, such as distinguishing between ruby and spinel. Check if the round brilliant diamond has eight hearts and eight arrows. Use a penlight to observe whether the gemstone has cracks. A penlight can also be used to observe star effects or cat's eye phenomena; a yellow light source can also be used to check for color change in the gemstone. Use a microscope to observe inclusions in the gemstone, preferably with both eyes open. First, adjust the inter-pupillary distance until two images merge into one, then change the microscope magnification from low to high to locate the gemstone. After seeing the gem, adjust its position slightly with the right hand and fine-tune the focus with the left hand until the distribution and types of inclusions in the gem are visible.
