Cut

A diamond’s cut is not only about its shape, but how effectively the stone can return light back to the viewer's eye. A well-cut diamond will appear very brilliant and fiery; while more poorly cut stones can appear dark and lifeless, regardless of color or clarity.

Diameter: Width of a polished stone, measured from edge to edge

Table: Largest polished facet located on the top of the diamond

Crown: The top part of a diamond extending from the table to the girdle

Girdle: The very edge of the diamond where the crown and pavilion meet

Pavilion: The bottom part of a diamond extending from the girdle down to the culet

Depth: The total height of a diamond measured from the table to the culet

Culet: The small or pointed facet at the very bottom of a polished stone
The 4c of GlA

color

Colorless (D-F): Diamonds within the colorless range are the most rare and valuable of all the colors. D/E color stones display virtually no color, whereas F colored diamonds will display a nearly undetected amount of color when viewed face down by a gemologist..
Which Color should you Choose? Most people find it very difficult (if not impossible) to tell the difference from one color grade to another. The difference in price, however, can be significant. The purists at heart will always demand diamonds in the D-F range. By selecting diamonds in the G-I range, however, you can find a tremendous value while still achieving a "colorless" look. Shopping on a budget or trying to maximize the size of your stone? If so then "J" diamonds are most affordable and still near colorless. You may also want to consider choosing a diamond with medium or strong fluorescence. Since these diamonds are discounted slightly in price you can often afford a higher color stone without paying the premium.
Grades

clarity

Clarity refers to the presence (or absence) of impurities, blemishes or other identifying characteristics within a diamond. Clarity characteristics are what make every diamond completely unique. There are no two diamonds that will have exactly the same inclusions in the same location.

VVS1/VVS2 Diamonds: Very Very Slightly Included: Contain minute inclusions that are extremely difficult for an experienced grader to locate under 10x magnification. VVS diamonds are very rare and beautiful.

VS1/VS2 Diamonds: Very Slightly Included: Contain minor inclusions that range from difficult to somewhat easy to see under 10x magnification. Typical VS inclusions are small crystals, feathers or distinct clouds. In some rare cases, a VS stone can contain an eye visible inclusion. Excellent quality diamonds.

SI1/SI2 Diamonds: Slightly Included: Inclusions are easily visible under 10x magnification to an experienced gemologist and may be visible with the unaided eye. A great value.

I1/I2/I3 Diamonds: Included: Diamonds with significant inclusions. Best suited for use in diamond jewelry..

diamond certification

A certificate is a blueprint of a loose diamond. Wholesalers, retailers, and consumers alike know a certificate as either a diamond grading report or diamond dossier. A certificate will tell a diamond’s exact measurements, weight, cut and overall quality. A certificate will precisely point out a diamond’s individual characteristics as well as be a useful tool when identifying a stone. When shopping for a loose diamond, considering stones that have a grading report will allow you to make an informed decision on which diamond will be ideal for you.

cart welght

Carat is a term that refers to the weight of a diamond. Before the twentieth century, diamonds were measured by using the carob seed that is small and uniform and served as a perfect counter weight to the diamond. It is those original carob seeds which are the origin of the word carat we use today. The majority of diamonds used in jewelry and sold loose in the United States are one carat or less in weight. The average engagement ring diamond sold in the US is less than 1/2ct in weight.
When rough diamonds are cut and polished into finished diamonds, as much as 2/3rd of the total carat weight is lost. Because larger gem quality rough is found less frequently than smaller rough, a two carat diamond will be far more expensive than two one carat diamonds of the same quality.

Gold

Gold won't tarnish, rust, or corrode, and though it's very strong, it is also the most malleable of all metals.

purity

Pure gold is too soft to withstand the stresses of every-day wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Karatage, noted by a number followed by "k" indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold 100% gold.

color

The color of gold is determined by two factors:
  • The type of metal alloys included in it
  • The percentage of each metal alloy

Yellow Gold

18k gold contains more precious metal than 14k gold. It is composed of 75% gold, which is alloyed with other metals to make it strong enough to withstand every-day wear. Because 14k gold is composed of only 58.3% gold, and 41.7% other metals that give it strength, its gold color is not as rich as 18k gold. 14k gold is most commonly found in cases where strength is most important, like in earring backs and bracelet clasps.

White Gold

Because 18k white gold is 75% gold, and 14k white gold is 58.3% gold, jewelry made from these metals has a slight yellow color. To enhance the whiteness, almost all white gold is plated with rhodium, a shiny, white metal which is extremely hard. Depending on the amount of wear to a piece of jewelry, over time this rhodium plating may wear off, revealing the original metal color. Re-plating is a simple process that can be done to restore your jewelry's whiteness if needed.

Rose Gold

Rose gold gets its color from a larger proportion of copper in the metal alloy. This gives the gold a beautiful pink color.

pricing

The price of gold jewelry is dependent upon the purity of the gold used or karat weight, as well as the design and construction of the piece of jewelry.

care

Keep your gold jewelry away from harsh chemicals such as chlorine and cleaning fluids. This will reduce daily abrasions and prolong gold's luster. To clean gold jewelry, use a solution of warm water and detergent-free soap and wash gold gently with a soft-bristled brush (a dull tooth brush works well). Store gold pieces separately in soft cloth bags or original boxes to protect them from the exposure to harsh daily elements.

silver

Pure silver, also called fine silver, is relatively soft, very malleable, and easily damaged so it is commonly combined with other metals to produce a more durable product. The most popular of these alloys is sterling silver, which consists of 92.5 percent silver and 7.5 percent copper.

Although any metal can make up the 7.5 percent non-silver portion of sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness and durability without affecting its beautiful color.

The small amount of copper added to sterling has very little effect on the metal's value. Instead, the price of the silver item is affected by the labor involved in making the item, the skill of the craftsperson, and the intricacy of the design.

stamps of quality

Most high quality silver items are stamped with a "fineness" or "quality" mark. This mark designates the precious metal content of the jewelry, and under federal law, must be accompanied by a maker's mark or registered trademark.

silver alloys

Because pure silver is so soft, it should only be used when malleability is required, such as in handcrafted jewelry featuring weaving and other intricate designs.

Sterling silver is most often used for jewelry and household accessories because of its combination of beauty and durability. Acceptable quality marks for sterling silver include:

  • sterling
  • sterling silver
  • ster
  • .925

care

With proper care, your fine quality silver will last a lifetime. To minimize scratches and other damage, store your silver jewelry either in a cloth pouch or in a separate compartment in your jewelry box. Avoid exposing your silver to household chemicals when cleaning with bleach or ammonia, or when swimming in chlorinated water, as these chemicals can damage silver.

clean your silver regularly

Care should also be taken to prevent silver tarnish build-up, a dulling that naturally occurs when silver reacts with sulfur or hydrogen sulfide in the ambient air. To clean your silver, use polishes formulated specifically to remove tarnish. You can find fine silver polishes, solutions, or cloths appropriate to remove tarnish at most hardware stores or specialty craft stores. Tarnish is most easily removed when it first becomes visible.

Although wearing your silver jewelry often is the best way to prevent tarnish from building up, regular cleanings of all your silver items will prevent tarnish and keep your silver bright and sparkling.

Look for the fineness mark and the maker's mark on the underside of the silver item you are considering to ensure the quality.

Rhodium

Rhodium Plating provides protection for our sterling silver and white gold jewelry by coating to help prevent tarnish and surface scratches. A rhodium finish however is not impervious to the effects of wear and abrasion that may occur in everyday use. To limit wear, one should avoid household cleansers, gardening and other activities that can quickly destroy the rhodium plating, thus exposing the slightly yellow tint.
Even talc, which is found in many cosmetics, is known to have an abrasive effect on jewelry items. White gold may appear slightly yellow. Sterling silver may tarnish. Here are tips for keeping your Rhodium Plated jewelry looking its best:

  • Do not use any abrasive cloths for polishing
  • Do not use chemical cleaners
  • Clean only with mild soap and water.

stainless steel

With the aesthetic appearance of platinum, 1,000 times stronger and a third part of the cost, stainless steel, includes corrosion-resistant properties that increase its strength and long-term value. Used and recommended by surgeons worldwide, stainless steel does not emit toxins or chemicals that cause allergic reactions. The stainless steel jewelry does not lose its luster, and require minimal care and which do not rust or break. So the answer is quality. We guarantee that you will feel loved stainless steel.

10 Reasons to use Stainless Stell
  • Hypo-allergenic - No Cause Allergies
  • No stains, or rust
  • Maintains its color and brightness
  • Easy to maintain
  • No breaks
  • Resistant to wear everyday
  • It is 1,000 times stronger than platinum
  • Its price is very comfortable
  • It is 100% recyclable
  • Looks great in jewelry

care

In most cases, this material is very easy to clean, and requires no great demands. Therefore, to effectively clean and fast just have to lavarcon a cleaning detergent or soap. Just make sure it is smooth.

In the case of other stainless steel surfaces, it is important to avoid the stains left by chlorine and other substances containing water and lime stains. If the stain is very recent, just dry with a dry cloth.

If the stain is a bit old, and I is difficult to remove, you can pass a cloth with hot vinegar and then wash as usual and dried.
