wholesale jewelry display nyc 30th street How to choose diamonds in jewelry shops

wholesale letters for jewelry Diamond refers to diamonds that have been considered. Vajra is a natural mineral and the rough of diamonds. The diamond selection skills I organized for reference!
1. First, select the weight -In the budget range, try to choose enough weight
The standard round diamond weight (carat) and diamond size schematic diagram
basically determines the size of the diamond. It is the most sensitive and intuitive human eye. Although the diameter is only a few millimeters, the difference is 3-5 points (different from person to person), and there are obvious changes visually. More importantly, the optical performance of diamonds (especially Huotai) is more than 30 points, and the performance is more complete, and it can be fully reflected in 70 or more. Therefore, if you choose a wedding ring, it is not recommended for 30 points, and many of the other diamonds below 30 points do not have a standard 57 section.
2. Make sure that the glory is the soul of the diamond, at least VG or more
In the imagination, not flashing or vivid stones, even if it is big, it is the same as the crystal ... Essence Cutting level is the second life of diamonds. A good cut means that the pursuit of visual reflection does not hesitate to achieve the best optical effect balance.
The cutting level: IDEAL (AGS) — EXCELLENT -VORY Good… (cutting below G can be ignored)
It, 1 carat's hair embryo, ideal cutting can only be retained 0.5.5.5.5.5.5.5.5.5.5.5.5.5.5 Clarks' diamonds, but the secondary cut can retain 0.7 carats to pursue commercial value (especially markets with low education).
3. Preferably color -H color or above, single grains do not show yellow
The color relative clarity is easier to feel. The whiter the diamond is more transparent, and the color resolution of light is stronger. Leaving aside the shot lighting effect of the mall, only in terms of the color of natural light, in general, H color is the watershed of yellow and white.
· If the pursuit of cost performance, the first choice: F, G, H color
· If the budget is abundant, the pursuit of quality: D, E color
· I do not recommend it, the market is flooded at low prices M — N color, strongly recommended to avoid.
· Color system is: D, E, F, G, H, I, J ... Z (from white to Huang Yizhi)
4. Clearness -10 times the "rare degree under the large mirror mirror" scarce degree "
The clarity is the description of whether the internal diamond is" clean ", provided that 10 times the large mirror. It means that the basic people are not visible to the naked eye, and diamonds are unavoidable to contain impurities (as long as the multiples are enlarged). The precautions affect diamond investment attributes. As a need for wearing, it can be retained until the final consideration. However, the SI1 level (some si1 contains the deep position in the shape, and you need to choose) is basically the bottom line.
· cost -effective preferred: vs1, vs2
· Quality pursuit: VVS1, VVS2
· Investment collection: IF
Diamonds with clarity, such as I -J, VVS clarity. It is a sluggish product worldwide, whether it is worn or preserved, it doesn't make sense.
· The clarity is the most controversial, because there are often "drop -level" situations, especially when choosing a diamond with a suffix (VS2 especially). Whether the position of the content is facing the table and whether the color is obvious.
· VS2 has always been touted by the market "cost -effective", but GIA's VS2 re -inspection will fall to the SI level in 10 of 10. Low, be cautious!
do not ignore the cutting of the diamond
The size of the diamond is the most important. But this is not the only factor affecting the quality and price of diamonds. In addition to carat weight, the value of diamonds is as good as the quality of the cut, color and clarity. Especially the good or bad of cutting can not be ignored. More people will be called the second life of diamonds. According to the standard of GIA, cutting can be divided into five levels:
, excerration or ideal/ideal Cut the standards that can only reach the standard of first -class high -quality diamonds.
2. Very Good/Very good cut -recently similar to ideal cutting, about 15%of diamonds meet such cutting standards. Essence
3. Good/good cut -the price is lower than the very good -level cut diamond. About 25%of diamonds meet this cut standard.
4. FAIR/General cutting -about 35%of diamonds meet this cutting standard.
5. Poor/differential cutting
This work has a great impact on the price and fire color of diamonds. When choosing diamonds, do not buy diamonds that are not cut in order to save money. The above.
does not necessarily require high clarity, good color diamonds
It some consumers strive for perfection, and must buy diamonds with good color and high clarity. However, buying diamonds not necessarily must be high -clarity and good color diamonds. What metal you use and inlaid on what metals are inlaid. If you just wear it daily or inlay on white metals, such as 18K platinum, platinum, then diamond color reaches I i —J color is fine, and for small diamonds below 0.25CT, the clarity does not have to be too high, as long as the diamond has a fire color.
The skills to buy more affordable diamonds
1. Make sure you have the most brilliant fire when you buy big diamonds.
The most charming part of the diamond is the flashing and charming glory, and the diamond fire color is mainly determined by cutting. The color of diamond color and diamonds affects the fire color of diamonds, as long as it is cut to maintain the level. In the evaluation system of "GIA" diamonds, there are many projects related to cutting, but only three of them are the "CUT (comprehensive indicators)", "POL (polishing indicators)" and "SYM (symmetrical symmetry) (symmetrical (symmetrical (symmetrical)" Sexual indicators). ". If the customer can ensure that the "comprehensive indicator of cutting" can reach "EX (excellent)" when purchasing carat diamonds, then even if the other two cut indicators are only "VG (very good)", they can also ensure the purchase of carats purchased. Diamond has a good fire color.
2. Avoid critical weight diamonds
In diamonds, 30 points, 50 points, 1 carat diamonds are very popular diamonds, a critical weight diamond. There is a "carat premium" phenomenon. Even if there is only 1 point, 99 points are far from the price of diamonds of 1CT. But they are very distinguished from the size of the naked eye. But the price is very different. Avoid when buying. Especially when wearing.
3. The color, size and location of the defects in the diamond body should be controlled.
VS and SI -level diamonds clearly contain "micro flaws" in the standard. The smaller the flaws, the lighter the color, the absolute choice. To prevent defects from reflecting and enlarging due to light refraction, it is convenient to effectively cover it with claws when inlaid.
4. Pay attention not to let the chosen carat diamonds have fluorescence that affects the appearance.
The diamond fluorescence is divided into white, blue, yellow, purple and other types. Among them, the fluorescence is strong. It can be observed with the naked eye, while the low fluorescence needs to be placed under the ultraviolet light to appear. For some relatively large diamonds, general weak fluorescence can affect the price of about 5%, and medium fluorescence will affect about 7%-10%. The greater the strong fluorescence on the higher -colored diamond, even more than 30%.
