Metal

The fineness of gold utilized to set a piece of jewellery plays an integral role in its durability. At Bee’s Diamonds, we use the purest forms of gold in our products, consisting of either 18K gold, platinum or titanium. All jewellery bear a mark indicating the fineness of gold content and a detailed invoice or receipt stating the content will be issued at collection or delivery.

18K Gold (White / Gold / Rose / Black)
The standard of fineness for 18K Gold is 750. This refers to the gold content being 75% gold and 25% being other gold alloys, including palladium and silver. 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
For customers who may have slight risk of skin allergies towards the gold alloys used in 18K gold, we recommend setting your diamond onto platinum which is a dense, malleable, ductile precious, gray-white transition metal. The majority of platinum jewellery is 95% pure platinum combined with 5% iridium, palladium, ruthenium or other alloys.

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.

Titanium
Titanium is increasingly becoming popular as a jewelry material due to its unique properties. It is hypoallergenic, lightweight and corrosion-resistant. It is also non-toxic to the human body. Titanium rings are therefore practical for those who regularly swim in ocean or chlorinated pools. However, titanium rings can have varying degrees of fatigue resistance and tensile strength. Titanium is comparable to steel in its resistance to sawing.

Finger Size

We understand that it is difficult to get to know the intended wearer’s ring size. At our consultations, our experienced gemologists can estimate her finger size. Alternatively, you can also attempt to obtain her suitable ring size:

• Take a current ring that fits the intended finger properly and bring it to our Bee’s Diamonds’ consultation for measurement
• Wrap a tight string (the texture and material of the string cannot stretch or twist which may yield an inaccurate measurement) around the intended finger and measure its length on a ruler*, this will give the inner diameter measurement for the ring
• Ask friends or close relatives of your ring recipient if they know his/her finger size
• Ask the intended ring recipient her ring size if this is not a surprise gift
• Find the ring size on Bee's Diamonds Ring Size Measurement Chart
• If you are located overseas, you can reference on a ring size that you try on at a nearby local jeweller. You may wish to check its corresponding finger size according to Hong Kong standards here.

*Be aware that finger size can change depending on the time of day and the weather. You are advised to measure the finger size at the end of day or when fingers are warm, or measure it 3 to 4 times to ensure accurate reading.

In order to provide full customer satisfaction, Bee’s Diamonds provide one time complimentary ring resize within six months after purchase.

Width

The width of a ring’s band refer to the distance between the top and bottom of the band which should not be less than 2 mm for durability and longevity. You can select your desirable width for a a tailor-made ring to be produced. Bee’s Diamonds recommends the following band width:

	Ladies Band	Men’s Band
Without any diamonds	2 to 3 mm	3.5 to 5.5 mm
With diamonds	2.5 to 3 mm	3.5 to 5.5 mm
