The factors to influence price are 4Cs – cut, carat, clarity, colour, leaving secondary role to proportions, fluorescence and other specifications. Price per carat for rounds varies from £1500 to £16000, so the happy medium is around £7000.

You can have fun doing some home tests you find on the internet. However better take a loupe and find the laser inscription on the girdle of the diamond.

Physical weight of diamonds is measured in carats. 1 carat equals 0.200 grams or 1/5 gram. 1 ct round diamond is usually equal 6.5 mm.

Two popular methods are CVD (chemical vapour deposition) and HPHT (high pressure high temperature). The main difference is the way a diamond grows. The result of each method will be a visually identical to natural diamond.

Because lab-diamonds are created in a steady, controlled process of applying minerals, heat and pressure. Also, they need much less time for growing than natural ones.

Take a loop or a magnifier glass to see the laser inscription on the girdle and identify the origin of the diamond. If there is no certificate number, contact local gem laboratory or jeweler.

Depending what diamond you choose (natural or lab-grown) and ring design (plain or with diamonds) an engagement ring will cost from £2300 with a synthetical and £6500 with a mined gem.

Ask your partner on preferences regarding diamond shape and ring style first. Then decide on the budget. Learn more about quality of metals for rings. Ask for expert advice when shopping for a diamond.

Plan your purchase beforehand, so you are in no rush. Compare offers from different retailers and study the terms and conditions. Get the measurements for the ring size properly. Buy certified diamonds only.

Wedding ring complements the engagement ring. Depending whether they have diamonds or not, what width and thickness they have, the price varies from £400 to £4000.

Based on your taste choose the preferrable thickness, width, diamond weight if any and ask for a quote. You can find a matching band from the same collection to sit flush with your engagement ring.

Eternal love, commitment, faith and unbreakable bond is embodied in each wedding ring. They are round like sun, moon and earth, arms to embrace and love, which when given comes back in a circle.

When buying earrings both online or offline make sure the metal or alloys won’t cause allergy. Ask for diamonds certificates and check terms and conditions.

Keep you jewellery in a box, so it is dust-free, safe and visible. Room temperature, low humidity, no direct sunlight, no contact with perfumes or lotions will make it shine longer.

Put some rubbing alcohol or hydrogen peroxide in the bottom of a glass. Submerge the earrings and leave them for ten minutes. Wipe them down with a cotton pad or microfibre cloth, then rinse. Alternatively take them to a jeweller.
