  1. 2019年10月26日 · 天女,由日本真珠科學研究所命名,代表了白色系akoya珍珠中的卓越品質。 日本真珠科學研究所所長小松博在2001年發現,在珍珠專用鑑定儀器的觀測下,可以看到在優質akoya珍珠下半球會出現3種干涉色,即“極光效應”。 具備了“極光效應”的akoya珍珠且直徑在6mm以上的,即命名為“極光天女”,一般簡稱為“天女”。 關於珠層: 天女珠層的標準為0.4mm,0.4mm以下的不可評定為天女。 很多賣家宣稱,珍珠層越厚珍珠光澤越美,很多買家也深以為然。 然而事實並非如此。 珠層並非越厚光澤越好,珠層厚度與光澤、瑕疵沒有直接聯繫。 決定珍珠光澤的是珍珠質單層結晶層之間的排列疊加是否平整緊密。

  2. 2019年6月27日 · 1.獨家的RZ®人造鑽: RZ人造鑽石是經過香港商標註冊的一款高仿人造鑽石,採用與傳統鑽石相同的八心八箭以及D色FL淨度3EX的標準進行切割。 讓人造鑽石看起來保證100%肉眼無差別。 相比一般市場上的仿鑽更像真,沒有蘇聯石 (高碳鑽)的死且膠的質感,也沒有莫桑石 (魔星石)的重影朦朧問題。 2.價格只需鑽石的1%: 相對天然的鑽石來說,RZ人造鑽石除了不能經過專業的鑽石儀器測試以外。 其他在肉眼層面都是相同的,對於一般外在要完全相似而不想花費太多或想要做日常替換或多點款式的顧客來說是非常便宜的方案! 起碼…不會買到破產. 3.永不變色變矇: 如果您有經歷過選購仿鑽的經驗,必定試過剛剛買的時候覺得很閃很亮。 但過了大約幾個月之後,手上的仿鑽越來越發白,越來越朦朧,塑膠感越來越重。

  3. 2020年12月14日 · Roselle Jewelry所出售的銀產品均有6層的鉑金鍍層,一般耐用可以維持大約3-5年 (與一般鍍K金/銠金的產品相比更耐用) 負擔能力. 銀是最廉價的珠寶金屬之一,非常適合隨衣櫃旋轉的人造珠寶。 但是,白金的超強耐用性確實增加了金屬的價格。 白金的價格高於白銀,但低於鉑金,因此價格適中。 重量. 由於銀和白金的密度不一樣,所以比重也是會有1:1.4的分別。 可以參考下面的圖片. S925 銀 (鍍鉑金) 18K 白金. 銀是完全無法製作白金的重量。 如果在坊間找到1:1的重量,基本是銅材質。 而這種銅材質會讓手會有過敏反應。 結論. 如果您是想要和鑽石店購買的完全一樣,可以長久佩戴。 建議選擇白金。 如果您是玩耍的性質,一兩年更換不同款式。

    • 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...
