4 FOOLPROOF WAYS TO FIND HER RING SIZE

LEARN MORE

STONES GUIDE

Learn about stones with our Stones Guide. Need help? Contact Us

  • Earth Created stones
  • White Diamond
    White Diamond - the most luxurious and prestigious gemstone for jewelry. The Diamond is a stone that symbolizes love and purity, and that’s why it is the most adored choice for engagement rings and wedding bands. Today it’s hard to imagine an engagement ring without a Diamond as the central stone. White Diamond is the most elegant choice that will always be appreciated and beloved by her.
  • Black Diamond
    Black Diamond - unique and elegant gemstone. It shares all symbolism of the White Diamond and, at the same time, has its own additional “flavor.” This unique gemstone is much rarer than other kinds of Diamonds. It represents power and passion; in many cultures, it is also claimed to bring blessing and good fortune. Black Diamond combines originality and uniqueness and is one of the most fashionable gemstones in the world.
  • Green Emerald
    Green Emerald - highly versatile stone that works with a wide variety of designs and settings. It can be successfully used in traditional and completely modern jewelry designs. Green Emerald symbolizes fidelity and true love. It’s a perfect choice for those who value unique beauty and non-traditional statements.
  • Red Ruby
    Red Ruby - the stone that has one of the most intense and rich lusters. It symbolizes passion, devotion, and love. Rubies are rare and beautiful stones. They will always look stylish and attract admiring looks. It’s a gemstone with a strong temper and a significant connection to its owner’s individuality.
  • Blue Sapphire
    Blue Sapphire - the stone that fascinates with the depth of its Blue color. It symbolizes truth, love, purity, and sincerity. Since ancient times Blue Sapphires have always been considered a royal gemstone. Blue Sapphire will make her feel like a Princess on any occasion, in every place.
  • Lab created Stones
  • Premium Moissanite
    Premium Moissanite - the most significant advantage of Moissanite is its price. If you want a jewelry piece with a large stone but don’t have enough money for a Diamond - Moissanite is the best choice. Also, Moissanite is the second hardest to Diamonds, which makes it a highly durable gemstone.
  • Premium Moissanite
    Lab-created White Diamond - Lab-created Diamonds are actually Diamonds, on a molecular, chemical, and optical level. The only difference is that a lab-created Diamond was made in a lab in a matter of many months, rather than the millions of years for a Natural Diamond to be formed on the earth.
  • Black Diamond
    Black Moissanite - Black Moissanites are Diamonds that are grown in a laboratory, rather than in the natural environment. They are made by heating Diamond powder to high temperatures and then letting it cool slowly, allowing the Diamond to form in a different shape than when mined.
  • Green Emerald
    Lab-created Emerald - a synthetic Emerald is a man-made Emerald. It has the same chemistry, scratch resistance, and color as Natural Emerald, but made in a lab instead of the earth. Not to be confused with Emerald simulants, which are things meant to look like an Emerald.
  • Red Ruby
    Lab-created Ruby - Lab-created Rubies, also known as created, lab-grown, synthetic, cultured or man-made Rubies, are gemstones grown in laboratories with human aid under controlled environments. They have identical chemical compositions to their natural counterparts (Al2O3) and the same optical and physical properties.
  • Blue Sapphire
    Lab-created Sapphire - Lab-created Sapphires are made using corundum, just as the Natural Sapphire is. However, they are created in a laboratory and grown under carefully controlled conditions, simulating the high pressure and heat of the earth to replicate a Natural Sapphire. The heat used to create them comes from a machine. Lab-created Sapphires do not scratch or chip more easily than the natural stones and are valued for their quality.

Necklaces Size Guide
  • 16 inch (41 cm)
    Falls perfectly around the base of the neck like a collar. On a petite woman it will hit your collarbone while for plus size women it might feel more like a choker.
  • 18 inch (46 cm)
    A common choice for women that will fall just below the throat at the collarbone. This length is popular for adding pendants which will hang over a crew neck.
  • 20 inch (51 cm)
    Will fall a few inches below the collarbone and allow a little more breathing room. Perfect for a low, plunging neckline or if you want to wear it over a turtleneck.
  • 22 inch (56 cm)
    Falls at or above a low neckline.
  • 24 inch (61 cm)
    Falls below any neckline.
  • 30 inch (76 cm)
    Common with pearl strands and will hang below the bosom. They can be worn as a single strand or you can double them for an 18 inch necklace.

About metal types
14K GOLD
14K Gold jewelry pieces contain 58.3% Gold combined with other metals, which makes this option more durable and resistant to damage that can happen in daily life. This is a perfect choice for people with an active lifestyle.
18K GOLD
18K Gold jewelry pieces contain 75% of Gold This makes it look richer in Yellow Gold and more brassy in the Rose Gold option (instead of the pink look of 14K Rose Gold). 18K White Gold usually looks whiter and brighter than 14K White Gold
PLATINUM
Platinum is the most prestigious and exclusive metal. Platinum is one of the hardest metals, which doesn’t corrode, discolor, or lose shape. It’s one of the best options for jewelry pieces.
