We set high standards for our jewelry sourcing - whether natural or lab-created, 100% of our diamonds are conflict-free. Check out more reasons to choose KAY here. All lab-created diamonds are independently certified for color, clarity, cut, and carat weight.

Kays diamonds are almost exclusively IGI certified; on average an IGI certified diamonds come in around three grades higher than their GIA equivalent.

This means that diamond jewelry is often imitated and sold as a real diamond. If you have been sold a fake diamond it is most likely to be CZ (Cubic Zirconia), an imitation created in a lab. While some choose to knowingly buy and sell CZ gems, others attempt to exploit the industry and sell them as real diamonds.

Remove your jewelry before showering, swimming, cleaning, sleeping, doing rough work or handling chemicals -- including hair care products and perfume. Do not expose gemstones to sudden temperature changes, which may cause cracks. Store each piece of jewelry separately to prevent them from scratching each other.

At KAY we are committed to using ethical, conflict-free and sustainable supply chains to create the jewelry you love.

If the setting is gold-filled or gold plated, or even 10 karat gold, that's a low-end setting. Sterling silver is trickier: sometimes diamonds are set in silver. A designer piece (like David Yurman, John Hardy, Lagos, etc.) is likely to have real diamonds, but cheap silver will likely have diamond simulants.

Yes, some diamond simulants can pass a diamond tester. For example, moissanite, a man made gem, may pass as a diamond on a standard tester pen. This is because moissanite also has very high thermal conductivity! Other diamond simulants, such as CZ, will not pass the tester.

Now you might also be using cologne perfume you might be using. Several different lotions.

Overall, if you're looking for quality customer service from a jewelry store then Kay Jewelers is not the place to go. With unhelpful staff, delayed responses, and poor returns policy – there are much better options out there!

The bad news is they don't hold their value quite the same as natural diamonds. Depending on the current diamond industry market, a natural diamond typically holds around 25% to 50% of its value, while by some estimates, lab-grown diamonds may hold little to no resale value.

moissanite Hands down, moissanite is the number one alternative when it comes to the best fake diamonds for a number of reasons. First of all, moissanite has a hardness that rivals an actual diamond. Diamonds rate 10 on the hardness scale, but moissanites come in a very close second, at 9.25.

The diamond tester works on the principle of thermal conductivity (because diamonds are SUPERB conductors of heat due to their compact covalent structure).

Many pieces can be washed with soap and water or placed in a jewellery box with a soft cloth for protection. Sterling silver jewelry can absolutely be worn every day! In fact, many people enjoy the look of sterling silver because it's understated and timeless.

Sterling silver normally lasts 20 to 30 years if the owner cares well for it. However, your sterling silver can last forever if you care for it properly. Made up of 92.5% silver and 7.5% copper, sterling silver requires some special care. If you own any sterling silver jewelry, you should know how to care for it well.

They are considered to be one of Sterling Jewelers' premium brands, however while the prices are certainly on the premium end of the jewelry spectrum, the quality of their diamonds is well below par.

A diamond tester will only test positive for diamond and moissanite. Synthetic moissanite has been used as a gemstone only since the 1990s, so if your piece is from an earlier era, it's definitely a diamond if it passes this test!
