摘要:
A variety of techniques for creating reliable signatures of jewelry and gemstones is provided. These signatures can be used as references for later authentication of the jewelry and/or gemstones. With some examples, blockchain may be used to reliably store the reference signatures for later use during authentication, and a digital asset such as a non-fungible token can link these reference signatures with the physical jewelry/gemstones. Reference signatures can uniquely identify the jewelry/gemstones based on their optical, acoustical, electromagnetic, or other physical characteristics. Artificial intelligence and machine learning techniques (such as convolutional neural networks) can be used to determine which feature characteristics of jewelry/gemstones are to serve as the reference signatures.

A variety of techniques for authentication of jewelry and gemstones is provided. With some examples, blockchain may be used to store a reference signature for the jewelry/gemstone, and a digital asset such as a non-fungible token can link this reference signature with the physical jewelry/gemstone. During an authentication process, the reference signature stored on the blockchain can be accessed and compared with a test signature derived from an item that is purported to be the original jewelry/gemstone to determine whether they match to support a declaration that the purported jewelry/gemstone is authentic.
摘要:
One variation of a solid carbon composition forms a solid carbon product derived from a hydrocarbon mixture: including methane including carbon sourced from captured gas; and formed via methanation of a carbon dioxide mixture extracted from captured gas via a point source capture process. The solid carbon composition includes carbon sourced from captured gas and including: a first amount of carbon-13 isotopes; and a second amount of carbon-12 isotopes. The solid carbon composition exhibits an isotopic signature defining a ratio of the first amount of carbon-13 isotopes to the second amount of carbon-12 isotopes exceeding −50.0 parts-per-thousand-versus-PDB-standard.

A jewelry kit having a shape having at least one side wall with at least one side wall, a front side and a back side. The at least one side wall has a corresponding grooved rim forming at least one edge. The at least one edge spans the length of each side wall. The edges form at least one interior portion for receiving a plurality of objects. The kit also has at least one bale. The at least one bale has a jagged strip extending from the front side of the shape having the at least one side wall and culminating in a looped piece on the back side of the shape having the at least one side wall. The jagged strip attaches to the at least one edge of any of the at least one side walls. The looped piece culminating in a securing means for attaching the at least one bale to the shape having the at least one side wall.
摘要:
A diamond, which has an arched configuration on one end and a baguette-style configuration on the other, comprising a girdle, a top or crown above the girdle, and a pavilion or base below the girdle, The crown terminates in an upper planar surface known as a “table,” which is generally parallel to the girdle plane. The arched end is comprised of a series of crown facets that are preferably arranged about a common center. The pavilion also includes several sets of inner and outer pavilion facets where the inner pavilion facets terminate at respective lowerbreak lines.

A light-emitting jewelry piece includes a gemstone, a head, and a mounting. The head is configured to interconnect the gemstone to the mounting. The mounting is arranged secure the light-emitting jewelry piece to a person or a personal adornment.
摘要:
A method to apply nano-crystalline diamond onto a selected substrate, including preparing Nanodiamond slurry of nanodiamond particles dispersed in a medium. The medium may include a liquid or a sol-gel. The selected substrate is immersed in the Nanodiamond slurry for a predetermined period of time. Then the substrate is removed from the slurry. The substrate is then dried with a flow of inert gas. The substrate is left coated with a coating of the nanodiamond particles that are highly adherently held by van der Waals forces.

The invention relates to an ornamental device (1) comprising at least one cut or polished stone (2) with at least one rear portion (23).This ornamental device (1) is characterised by 5 the fact that it also has: means (3) to at least partially protect the rear portion (23) of the stone (2) from becoming soiled. This means of protection (3) takes on the shape of this rear portion (23) of the stone (2) and equips this rear portion (23) of the stone (2) without adhering to it; means (5) to prevent the ingress of a body from between the rear portion (23) of the stone (2) and the means (3) for protecting this rear portion (23) of the stone (2) and/or to prevent the egress of such a body from a defined internal volume (4) between the rear portion (23) of the stone (2) and the means (3) for protecting this rear portion (23) of the stone (2); Means for securing, on the stone (2), means (3) for protecting the rear portion (23) of this stone (2). The invention also concerns a manufacturing process of such an ornamental device (1).

The specification relates to a gemstone setting. The gemstone setting includes a gemstone, a mounting surface and a braze joint. The braze joint is formed from a reactive metallic alloy with the reactive metallic alloy adhering the gemstone to the mounting surface. The braze joint is substantially concealed from a direct line of sight from a top portion of the gemstone by preventing excessive alloy from getting outside a desired braze area.
