Lab Diamonds

Lab-grown diamonds are just that - diamonds.

They have the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle.

They can only be distinguished from natural diamonds by using specialized equipment.These diamonds are grown in highly controlled laboratory environments using advanced processes that mimic the conditions under which diamonds naturally develop when they form beneath the Earth’s crust.

Lab-grown diamonds cost significantly less than natural diamonds, offering consumers an affordable alternative.

Diamond Grading

The first step in choosing the perfect diamond is determining the shape that most suits your personal style.

The Four C’s (carat, cut, colour and clarity) are primarily used to determine the quality and overall value of a diamond.

Your personal preferences will determine which one of the four is the most important.

The colour of a diamond drastically affects the overall look and value of the stone. The colour is graded from D, being colourless, to Z, containing the most colour.

If you want that pure white look try to stick to the colours D to J. Also, don't be scared of warmer coloured stones when warmer metal is your preferred choice. The warmth in yellow and rose gold is complemented by a warmer stone and vice-versa.

And then we have our Fancy colours... Yes, diamonds come in every colour of the rainbow from black to pink and everything in between.

These colours are graded in their own way and can be a great investment.

A diamond’s clarity is graded from ‘Flawless’ to ‘Included’. But perfection is a rarity in the natural world. One can spend an entire lifetime in the jewellery industry without ever encountering a ‘Flawless’ diamond.

At Theia, we ensure that all of our diamonds are eye-clean, meaning the inclusions are too minuscule to be seen by anyone other than a trained eye using magnification.

Moissanite

Moissanite is truly an underappreciated gem.

When Moissanite was discovered in 1893 by a French scientist named Henri Moissan, he initially believed he had stumbled upon diamonds due to their captivating sparkle.

However, it was later revealed that, while Moissanite bears a striking resemblance to diamonds in terms of appearance, it differs significantly in composition.

Natural Moissanite remains very rare; thus, the majority of Moissanite on the market today is grown in a lab. On Moh’s scale of hardness, moissanite scores 9.25 out of 10, making it one of the hardest substances on earth and a great choice for everyday wear.

Brilliance, which refers to a stone’s ability to reflect white light, is a good measure of how much a stone will ‘sparkle’. Moissanite has a refractive index of 2.65 to 2.69, which is much higher than a diamond.

Moissanite also has a higher dispersion ("fire") than a diamond, meaning it will reflect more colors.

They are dramatically lower in price than a diamond of the same size and quality due to the fact that they are grown in a lab.

Jewellery Care

Fine jewellery is delicate and should be cared for to keep it in optimal condition.

Please follow our care instructions:

- Store your jewellery piece(s) in a safe location, lying flat, and where it won't touch or scratch another piece.

- Take off your jewellery before showering, bathing, or swimming.

- Do not adjust your jewellery yourself, but rather ask a professional jeweller to do so.

- Do not wear platinum and gold jewellery next to each other as your gold will scratch, due to the hardness of platinum. The same goes for silver, which is a relatively soft metal.

- Keep your jewellery away from all chemicals such as lotions, perfumes, hair sprays, and cosmetics.

- Take off your jewellery before sleeping or strenuous activities like cleaning or going to the gym.

- For necklaces and bracelets, clasp the necklace when removing it to ensure the chain does not tangle or knot.

Have your pieces checked and serviced by a professional jeweller every six months to a year; otherwise, you risk irreparable damage or even losing stones.

To clean your jewellery, mix a few drops of dish soap in warm (not too hot) water. Let your piece(s) sit in the solution for a few minutes. VERY GENTLY scrub the metal and diamonds with a soft baby toothbrush. To rinse, place the item in a new container of lukewarm water. This process should not be repeated more than once a week. Do not clean pearls with any chemicals, abrasives, or solvents.
