  1. 2022年5月30日 · 根據 GIA 傑出研究員 James Shigley 博士的說法,製造實驗室製造鑽石時使用了兩種方法。 第一種方法基本上模擬瞭如何使用高壓和高溫在地殼深處製造鑽石。 這種方法稱為 HTHP。 第二種稱為化學氣相沉積或 CVD 的方法涉及“將富含碳的氣體(如甲烷)的分子分解成碳和氫原子,然後將它們沉積在金剛石晶種上,以產生方形的板狀金剛石晶體 ”根據 GIA 官方教育網站。 與在地表深處需要數十億年才能形成的天然鑽石相比,實驗室製造的鑽石可能需要一個月左右的時間就能製成。 僅此事實就吸引了買家(您),因為他們通常會發現自然過程更加獨特,因此願意在其上花更多的錢。

    • How Are Lab-Created Diamonds Made?
    • Lab Grown Diamond Benefits
    • What Colors Are available?

    Each laboratory-created diamond is grown by placing a diamond ‘seed’ into a chamber of heat and pressure. This chamber mimics the natural growing process. Crystallization occurs allowing the lab-grown diamond to mature within six to ten weeks. It is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds. The...

    UNMATCHED BEAUTY

    Our collection of lab-created diamonds are available up to IF in clarity, D in color, Ideal in cut, and up to 10 carats in size. They come in a variety of shapesincluding round, rose, emerald, cushion, oval, oval rose, heart, princess, trillion, and radiant. Colors include white, yellow, blue, pink, and green.

    UNRIVALED QUALITY

    Unlike other retailers, every Rooselle Jewelry lab-created diamond is Type IIa, the purest form of diamond. They are harder and more brilliant than Type Ia diamonds. Only 2% of earth-mined diamonds are of this quality. Furthermore, each diamond is graded and certified by the same leading independent gemological labs that are used to grade earth-mined diamonds.

    UNBEATABLE VALUE

    Lab-created diamonds cost up-to 40% less than their mined diamond equivalents. Buyers beware: keep an eye out for "grown diamonds" sold for a few hundred dollars per carat. If the deal seems too good to be true, it probably is. Only diamond simulantsfall in this price range.

    WHITE LAB-CREATED DIAMONDS

    A pure carbon diamond with no impurities will grade as a colorless diamond. However, the majority of both mined and lab-created diamonds contain impurities, most of which are nitrogen. The nitrogen atoms within the diamond lattice create the yellow tint. In cases of fancy colored diamonds, a pure yellow color is created. Nearly all diamonds, both mined and lab-created, start out as yellow diamonds. Over the span of millions of years and exposure to pressure and heat, mined diamonds split the...

    YELLOW LAB-CREATED DIAMONDS

    Roselle Jewelry’s yellow lab-created diamonds are optically, chemically and physically identical to yellow earth-mined diamonds, but are offered free of conflict and on average 10% of the cost. They are available in a color range from fancy yellow to fancy vivid yellow, in sizes up to 2.0 carats and a variety of shapes. Both mined and lab-created yellow diamonds get their color from nitrogen. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of th...

    BLUE LAB-CREATED DIAMONDS

    Blue lab-created diamonds are optically, chemically and physically identical to blue earth-mined diamonds and are offered free of conflict and about 10% of the cost. They are typically offered in sizes smaller than 1.50 carats and come in a color range of fancy light blue to fancy intense blue. Both mined and lab-created blue diamonds get their color from boron. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of these impurities, in this case bo...

  3. 2022年5月30日 · 實驗室製造鑽石指南 在過去的 10 年中,實驗室製造的鑽石作為天然鑽石的一種經濟實惠的替代品,越來越受歡迎。實驗室培育的寶石可以輕鬆匹配任何天然寶石的光澤,但許多人認為它們不那麼稀有和珍貴。我們正在闡明是什麼讓這些實驗室製造的鑽石與天然寶石如此相似但又大不相同。

  4. 2022年9月27日 · 近年越來越多珠寶商改用實驗室培育鑽石,認為可減少使用與不道德生產方法有關的原材料;同時認為可降低生產成本,使更多消費者能夠購買到鑽石珠寶。 而根據安特衛普世界鑽石中心(Antwerp World Diamond Centre and Bain)的研究報告指出,實驗室培育鑽石市場目前正在迅速增長,尤其是年輕客戶特別熱衷於尋找可持續珠寶品牌。 兩者外觀上有何分別? 兩者不同只可由鑒定機構專業技術設備偵測,但肉眼難以分辨。 與天然鑽石有何不同? 兩者都是純碳打造,擁有一樣的光學特性,但培育鑽石可被無限制地創造,天然鑽石的形成則需要千年以上。 兩者價格有何分別? 天然鑽石的價格由每顆鑽石獨特的特徵和稀少性所決定,但人造鑽石則可大量生產,故價格比相同尺寸與品質的天然鑽石低很多。

  5. 旨在將注意力吸引到不同焦點的珠寶作品或設計元素. 幾乎可以在任何珠寶上添加口音,以有效地強調其他元素。 通常,口音是輔助設計元素,旨在通過提供紋理、顏色或兩者的對比來突出主要設計元素。 口音的對比不一定是明亮或戲劇性的——口音不是一個人首先註意到的,但是,它們為作品提供了整體平衡。 例如,重音鑽石是微型且可直接切割的寶石。 通常,它們被用作戒指或另一件珠寶的主石周圍的裝飾,以增加其整體光彩。 重音的另一個示例是金屬色,例如銀色或青銅色,它們為作品的主要顏色提供重音。
