Diamond & Jewellery FAQ — Rana Al Kuwait Jewellery

Question 1

Which of the 4Cs matters most?

Accepted Answer

Cut is the most important — it determines how much light a diamond returns to your eye. A well-cut stone of lower colour or clarity will always outshine a poorly cut stone with perfect grades.

Question 2

What colour grade should I choose?

Accepted Answer

G–H colour is the sweet spot for most buyers. The difference from D–F is invisible to the naked eye once set in gold, yet the price saving is significant.

Question 3

Is VS1 or VS2 clarity worth it?

Accepted Answer

Yes. VS1–VS2 diamonds are eye-clean (no inclusions visible without magnification) and cost considerably less than VVS or Flawless grades. We recommend VS for most engagement rings.

Question 4

Does carat weight equal size?

Accepted Answer

Not exactly. Carat is weight, not diameter. A well-cut 0.90ct diamond can appear larger than a poorly cut 1.00ct stone. Cut quality affects perceived size more than carat weight alone.

Question 5

Are natural diamonds better than lab-grown?

Accepted Answer

Natural diamonds are formed over billions of years and carry intrinsic rarity and long-term value. Lab-grown diamonds depreciate rapidly as production scales. At Rana Al Kuwait Jewellery, we work exclusively with natural, certified diamonds.

Question 6

What certificate should my diamond have?

Accepted Answer

GIA is the global gold standard. IGI and HRD are also highly respected. We provide certificates from GIA, IGI, HRD, SGL, EGL, EGLA, IDT, GRS, AIGS, and GII depending on the stone and type — all verifiable directly on the issuing lab's website.

Question 7

What is the difference between precious and semi-precious?

Accepted Answer

The four precious gemstones are diamond, ruby, emerald, and sapphire — defined by historical rarity and prestige. All others are semi-precious. However, rare semi-precious stones like alexandrite or tanzanite can exceed the price of many precious stones.

Question 8

Which gemstone is the most durable for everyday wear?

Accepted Answer

Ruby and sapphire (both corundum, Mohs 9) are the most durable coloured gemstones after diamond. They are ideal for rings and daily wear. Emerald and opal are softer and require more care.

Question 9

Are treated gemstones less valuable?

Accepted Answer

Most coloured gemstones are treated — heat treatment for rubies and sapphires, and oiling for emeralds, are industry-standard and accepted. What matters is disclosure. All our gemstones come with certificates that note any treatments.

Question 10

What is the rarest coloured gemstone?

Accepted Answer

Alexandrite is among the rarest — fine specimens with strong colour change are rarer than diamond. Tanzanite is also exceptionally rare, found only in a 4km² area near Kilimanjaro.

Question 11

Can I wear gemstone jewellery every day?

Accepted Answer

Ruby and sapphire: yes. Emerald: with care (avoid knocks and chemicals). Tanzanite, opal, and pearl: best reserved for occasional wear due to lower hardness and sensitivity to heat and chemicals.

Question 12

How do I know if a gemstone is natural or synthetic?

Accepted Answer

All gemstones we sell are natural and accompanied by laboratory certificates. Synthetic stones are chemically identical but grown in a lab — they carry far less value. Our certificates confirm natural origin.

Question 13

How often should I clean my jewellery at home?

Accepted Answer

For pieces worn daily, a gentle clean every 2–4 weeks keeps them looking their best. Soak in warm soapy water for 10–15 minutes, then gently brush with a soft toothbrush.

Question 14

Can I use an ultrasonic cleaner at home?

Accepted Answer

Ultrasonic cleaners are safe for solid-set diamonds in platinum or gold. Avoid them for emeralds, opals, pearls, tanzanite, and any pavé or channel-set pieces where stones could loosen.

Question 15

Why is my white gold turning yellow?

Accepted Answer

White gold is naturally yellow gold alloyed with white metals and coated in rhodium plating. As the plating wears, the natural gold colour shows through. Professional re-plating (a quick, affordable service) restores the bright white finish.

Question 16

How should I store my jewellery?

Accepted Answer

Store each piece separately in a fabric-lined box or soft pouch to prevent scratching. Keep away from direct sunlight, humidity, and extreme temperatures. Never pile pieces together.

Question 17

When should I take my jewellery to a professional?

Accepted Answer

Have prongs and settings checked every 12–18 months. Bring pieces in immediately if a stone feels loose, a prong catches on fabric, or you notice any damage. Prevention is far less costly than repair.

Question 18

Is it safe to wear jewellery in the pool or sea?

Accepted Answer

No. Chlorine in pools permanently damages gold alloys and weakens prong settings over time. Saltwater is equally harmful. Always remove jewellery before swimming.
