穩穩陣陣! 求婚戒指用4爪還是6爪指托較安全?

求婚戒指中最受歡迎的款式就是爪鑲,金屬覆蓋鑽石的部份相對其他鑲嵌方法少,光線能從四面八方入射及反射,不會被遮擋,能展現出最大程度的光學效果。 爪的數目以46較為普遍,既能穩固鑽石,又能表現對稱的美感。但當要選擇46時,應該選4還是6? 是愈多爪愈穩固安全嗎?

在選擇爪的數目時,您應考慮兩個因素:
第一,鑽石的大小,即鑽石的卡數。如果您的鑽石大於2.5卡,Bee’s Diamonds建議您選擇用6爪戒指托。因為2.5卡以上的鑽石對比戒指的大小為大,爪與爪之間的空間亦相對增加,鑽石被尖銳物件撞到或鈎到導致鬆脫的機會便愈大,因此大卡數鑽石應使用6爪戒指托較為安全。2.5卡以下的鑽石使用4爪鑲嵌便己足夠,當然,如您希望鑽石能更穩固,小鑽使用6爪是絕對可以的,可是您應考慮過多的戒爪會遮擋光線,鑽石的光芒可能會因而減少。

第二,根據戒指金屬硬度來決定爪的數目。普遍用來做戒指托的金屬有 18K金、鉑金PT950等。18K金是75%黃金混合25%貴金屬如銀、鎳、鈀,是硬度比較高的金屬。用18K金來做戒指托可放心根據第一點來決定爪的數目。相反鉑金PT95095%鉑金 5%貴金屬,屬於韌度較高的金屬,即金屬本質較軟,容易變形,有機會因輕微碰撞令戒爪鬆開,導致跌石。因此如需要用PT950,應考慮選用較多爪數,或加粗戒爪,增強對鑽石的保護。

鑽石是無比堅硬,不易受損的物質,經得起時間的洗禮,可是戒指托並不像鑽石般耐磨。無論是18K金,還是鉑金PT950,都有機會出現老化的情況,即戒爪有機會變得脆弱,更容易被撞鬆。因此Bee’s Diamonds建議您定期把戒指帶回珠寶店檢查,以防止鑽石鬆脫。

How to check if a diamond is securely and snuggly mounted on a ring?

Have you ever wondered why a diamond can be securely and snuggly mounted onto a ring with just a few claws? How can you check whether a diamond has become loose? Let us address your concerns with our gemological knowledge and experience.

There are multiple ways of mounting a diamond (or commonly referred to as, setting a diamond on a ring). The most common settings at all times are: channel setting, bezel setting, prong setting, drill setting and pave setting. Prong setting is the most commonly used, highly secure setting. Using 3, 4 or 6 prongs, a diamond can be securely mounted on a ring. As the structure of prong setting allows more light to go through and into a diamond, its brilliance and fire can be brought out through the play of light scintillation. That explains why the most classic and most popular engagement ring style usually features the famous prong setting.


Choice of Metal
Even though only 4 or 6 prongs are used to set a diamond in a ring, it can still be securely mounted if the craftsmanship is exquisite. Of course, prongs are susceptible to usual wear and tear like any other metals, but with the right use of metal and self-checking methods, you can be an expert in identifying whether a diamond has become loose from the ring. 

We recommend using 18K gold. Don’t mistaken 18K gold as the traditional typical yellow type of gold. 18K Gold jewellery can appear in white (silvery), black, purple, blue or even rose-colours. It is most commonly seen in white gold because of its strength to withstand normal wear and tear due to its rhodium plating which is extremely hard and it minimizes the jewellery’s vulnerability to scratches.

Platinum, often known as PT950, is a dense, malleable, ductile precious, gray-white transition metal. Although platinum is hard in nature, it is also extremely ductile and malleable which is not recommended for setting jewellery with refined details or with a valuable center diamond. Platinum is also vulnerable to daily wear and tear and can be susceptible to scratches resulted from constant contacts with hard surfaces.

Checking Methods
Treat your diamond ring as any other piece of fine jewellery, which should not be worn to rigorous sporting activities like swimming, racquet sports, etc. This can significantly reduce the risk of damages that may occur from excessive contacts of hard surface. There are three methods to know whether a diamond has become loose from its prongs.
1.    Touch and Feel!
You can gently touch and feel a diamond with the tips of your fingers to feel whether it has become loose from any of the prongs. If there is any slight movement, it is imperative that you bring the ring to fix immediately. 

2.    Slip it through!
If you are still not sure whether the diamond is loose, try slipping a piece of regular paper into the space between the tip of the prong and the diamond. If the paper can easily slip through that tiny little gap, your ring may be prone to movements.  At this stage, the diamond may not have come loose yet, but it is best that you bring the ring to a reliable jewellery to have it checked.

3.    Shake! Shake! Shake!
The easiest method to check whether a diamond is becoming loose is to shake it three times against your ears closely. If you hear some twinkling sounds, the diamond may have come loose from the ring. Stop wearing the ring immediately and have it check by a jewellery for quickest solutions.

Other than the three methods mentioned above, using a microscope or a magnification loupe is the most comprehensive method to check whether a diamond has indeed become loose. For instance, magnification loupes can identify whether a diamond is loosening from its bezel set and channel set where it is not easy to test its stability using the stated methods above. Another important piece of take away is not to store your jewellery together in unprotected environment with other pieces. Always baggage each piece of jewellery with at least a small plastic bag to avoid damages of the prongs.
