All gemstones have specific physical structures and chemical properties, and we recommend that you take good care of your jewelry during daily use. Treat them with cautious care in order to preserve their original gloss and elegance.

It is generally recommended that you avoid scratches and contact with chemical liquids, perfume, hair spray, and washing liquid when wearing the jewelry, as exposure to these irritants can easily reduce the gloss of the jewelry. Do not wear your jewelry during physical exercise of any kind. Housework, swimming, and any other sports activities may damage your fine jewelry.

After daily use, we recommend storing your fine jewelry in their original jewelry box and avoiding exposure to direct sunlight and humid environments. Do not expose your jewelry to the moisture of the bathroom for long periods of time. Fine jewelry adorned with diamonds and precious stones should be worn with caution and examined after a certain period of usage to avoid the risk of losing the stones.


Gold-Plated Jewelry Care

Gold-plated jewelry is composed of a solid, inner material like sterling silver and an outer material like 18k yellow, white or rose gold, rhodium or ruthenium.  Avoid heavy usage, as this can lead to the outer material rubbing off slightly. Over time, the outer material is likely to wear away, and this is considered a normal result of use rather than a defect. Gold-plated jewelry should be treated with the same caution outlined above to ensure that your pieces last as long as possible.


 Pearls Jewelry Care 

Pearls are organic gems with various colors. They are formed within the shell of pearl oysters and are expensive as far as natural gems go. The most valuable pearls occur spontaneously in the wild, but these are extremely rare. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of pearls currently sold on the market.

Pearls are delicate gems, and need to be handled with extra care. Their low resistance to heat and chemicals means that you need to avoid contact with creams, perfumes or similar. Simply rinse with water and dry with a soft cloth.


Colored Gemstone Jewelry Care

There are more than 3,000 kinds of minerals in nature, but only a few dozen of them are considered natural gemstones and used to manufacture jewelry. The most famous, precious natural gemstones include diamonds, rubies, sapphires, emeralds and chrysoberyl (cat’s eye).

Apart from diamonds, all gemstones are collectively categorized as colored gemstones, including diverse semi-precious stones such as tanzanite, opal, aquamarine, tourmaline, topaz, peridot, garnet, moonstone, and turquoise, etc.

Colored gems are natural mineral crystals. They come from the depths of the Earth, and they are often hidden in the rivers and seas. Impurities, variations and inclusions are the main characteristics of colored gemstones. All their natural features come together to create a unique beauty that prides itself on being natural rather than on being perfect. Natural gemstone is one-of-a-kind, and each piece of jewelry made from colored gemstone is a unique treasure with its own, individual charm.

Colored gemstones are fragile and do not possess the same durability as diamonds. When wearing colored gem jewelry, avoid scratching the jewelry with diamonds and other hard objects, and protect them from exposure to chemical liquids and humid environments. Gently use a soft toothbrush and tepid water to maintain and clean the colored gemstones, and apply neutral oil to keep the gloss. 


Diamond Jewelry Care

Diamonds are a solid form of carbon with cubic crystal structures, known as the hardest natural substance in existence. Diamonds are processed into diamond jewelry: the most valuable gemstone.

All diamonds used by Sinodic to create customized diamond jewelry are purchased from official diamond traders located primarily in the World Diamond Center in Antwerp, Belgium, according to the special requirements of our customers with their individual standards of quality.

You need to clean your diamond jewelry regularly to remove everyday dirt, dust, lotions and skin oils and ensure that it retains its sparkle. The simplest way to clean your jewelry is to mix mild dish soap and warm water and soak the jewelry in the mixture for about 15 minutes. Scrub the jewelry gently using a soft, bristled toothbrush to remove any dirt. You can also send your diamond jewelry to a professional jewelry shop to have it cleaned and checked. This will help keep the diamond shiny and prevent the risk of losing the diamond from your jewelry.

The 4 Cs of Diamonds

Clarity – measures the flawlessness of a diamond and correlates directly to its value. Diamonds are magnified at 10x power during grading, a process that assesses internal flawlessness (IF) based on the presence of internal flaws (clouds, feathers, pinpoints, crystals) and external imperfections (scratches, polish lines, nicks). Absolutely flawless diamonds are exceedingly rare.

Cut – refers to a style or design guide used when shaping a diamond for polishing, such as the brilliant cut. Cut refers to the symmetry, proportioning and polish of a diamond. A diamond’s cut is crucial to the stone’s final beauty and value. Of all the 4 Cs, cut is the most complex and technically difficult to analyze.

Color – the evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, it has a higher value. Each stone is then color-graded to a precise scale from “D” (colorless) to “Z” (saturated).

Carat – measures the weight of a diamond, and one carat equals 0.20 grams. Carat weight does not determine a diamond’s value, for example, two diamonds with the same weight of one carat can vary greatly in value when clarity, color, cut and fluorescence are taken into consideration.
