How to Buy Gems and Jewelry
1. First, it is essential to have the basic knowledge about
the 4Cs characteristics, Color - Clarity - Cut and Carat weight of
the gemstones/diamonds you are selecting.
2. The jewellers must provide another C “Confidence”.
Knowledgeable and generous jewellers can help and advise
customers to select the right gems and jewelry that suit their taste
and budget.
3. There are 2 categories of gemstones : precious stones
and semi - precious stones. Precious stones are diamond, ruby,
sapphire, yellow sapphire, emerald, etc. Semi - precious stones
are tourmaline, peridot, tanzanite, garnet, opal, spinel, zircon,
aquamarine, pearl, etc.
4. The commercial value, hardness and durability of semi -
precious stones are normally less than precious stones.
5. Two gemstones/diamonds of equal carat weight can
have very different values depending on their color - clarity and
cut. Therefore, remember to inspect their quality by using a 10X
magnifying loupe under the jeweller’s guidance.
6. Be careful with synthetic and imitation gemstones/
diamonds. For ruby and sapphire, be aware of mistaking and
paying the price of a blue gemstone for a sapphire and a red
gemstone for a ruby.
7. Prices of gold/silver/platinum jewelry are subject to
the weight and percertage of the material, craftsmanship and
designs.
