Taxes

Applicable taxes are included in the displayed price. Import duties or local charges may still apply according to destination.

Each LESHEM’S piece is carefully inspected before delivery. Manufacturing issues are reviewed individually; normal wear, accidental damage, impact, misuse and loss of stones are not automatically covered.

Contact us before sending a piece for inspection, adjustment or repair.

Store the piece separately, avoid impact and harsh chemicals, and remove it before sport, swimming or heavy work. Professional inspection and cleaning are recommended periodically.

White Gold
Polish and rhodium plating can change with wear. A jeweler can inspect the piece and, where appropriate, refinish or replate it.
Sapphire
Clean with warm water and mild soap, then dry with a soft cloth. Until treatment status is confirmed, avoid steam or ultrasonic cleaning and harsh chemicals. Mohs hardness describes resistance to scratching; it does not make any gemstone immune to a sharp impact.
Diamond
Avoid sharp impacts, especially around exposed edges. Clean with a lint-free cloth and mild household detergent. Steam or ultrasonic cleaning is best left to a professional who can first check that the stone and setting are secure.

A closer look

Crafted in Detail

Materials, stones and craftsmanship explained clearly by the people who create the piece.

Stone

Diamond

Diamond is crystalline carbon and ranks 10 on the Mohs scale, giving it exceptional resistance to scratching. Hardness is not the same as toughness, however, so a diamond can still chip or fracture from a hard impact.

Diamond is crystalline carbon: a single element arranged in a tightly bonded crystal structure. It ranks 10 on the Mohs scale, giving it exceptional resistance to scratching. Hardness is not the same as toughness, however; like any gemstone, diamond can chip or cleave if struck sharply in a vulnerable direction.

Stone

Sapphire

Sapphire is corundum in colors other than red, with blue being its best-known variety. At 9 on the Mohs scale, sapphire is highly resistant to scratching and well suited to jewelry worn regularly.
Learn more

Sapphire belongs to the corundum mineral family, a crystalline aluminium oxide. Red corundum is known as ruby, while sapphire appears across a broad palette of other colours. Ranking 9 on the Mohs scale and combining excellent toughness with no cleavage, sapphire is particularly well suited to jewellery designed to be worn often.

Metal

White Gold

White gold is a gold alloy made lighter in color by combining gold with white-colored metals. Many pieces are rhodium plated for a brighter finish; that surface layer can wear over time and may need professional renewal.
Learn more

White gold is a family of gold alloys rather than a single formula. Pure gold is mixed with white-colored metals to produce a paler color and improve working properties. Many pieces are rhodium plated to create a brighter, harder surface.

Karatage describes gold purity. Fourteen-karat gold contains about 58.3% gold and is commonly marked 585; the remaining alloy varies by formulation. A product’s exact alloy and surface treatment should be verified separately when relevant.

Setting

Halo

A halo setting surrounds the center stone with a ring of smaller accent stones, adding brilliance around it and making the center stone appear larger without changing its actual size.

Setting

Prong Setting

A prong setting holds the stone with small metal claws positioned around its edge. It leaves much of the stone visible and open to light, while the prongs themselves should be checked periodically for wear or movement.

Setting

Side Stones

A side-stone design places additional stones beside the center stone to add brilliance, color or visual balance while keeping the center stone as the main focal point.

Cut & shape

Cushion Cut

The cushion cut has a square or rectangular outline softened by rounded corners and curved sides. Its faceting can vary, but the shape is known for combining a soft silhouette with strong brilliance.

Cut & shape

Round Brilliant

The standard round brilliant is a circular diamond cutting style with 57 or 58 facets. Its facet arrangement is designed to create the visual combination of brightness, fire and scintillation associated with a well-cut round diamond.
