去年美國鉆石訂婚戒指的平均花費為7，011美元，比2020年增長6.1%，因為夫婦選擇了更大的寶石，更多的實驗室種植。

       平均而言，主石鉆石的尺寸從 1.20 克拉增加到 1.32 克拉。

       根據保險技術公司BriteCo的研究，近四分之一的夫婦正在選擇實驗室種植的石頭。實驗室制造鉆石訂婚戒指的份額從 2020 年的 19% 增長到 24% 以上。

       天然鉆石訂婚戒指的支出增長了近 12%，達到 8，053 美元，主石的尺寸從 2020 年的 1.16 增加到 2021 年的 1.25（略低于 8%）。

       實驗室種植的訂婚戒指平均售價為 4，383 美元，比上一年增長 8.6%，主石平均重 1.49 克拉（增長 11%）。

       BriteCo創始人兼首席執行官Dustin Lemick表示：“隨著千禧一代和Z世代作為新的求婚者登上舞臺，我們看到訂婚戒指的傳統偏好正在發生變化，以反映他們的價值觀。

       “越來越多的年輕人正在評估和購買實驗室制造鉆石，但天然的地球開采鉆石繼續占主導地位。

       The average spend on a diamond engagement ring in the US last year was $7,011, up 6.1 per cent on 2020, as couples opted for bigger stones, and more lab growns.

       The size of the center stone diamond size rose, on average, from 1.20 carats to 1.32 carats.

       And almost a quarter of couple are choosing a lab grown stone, according to research for BriteCo, an insurance technology company. The share of lab-grown diamond engagement rings grew from 19 per cent in 2020 to over 24 per cent.

       Spending on natural diamond engagement rings was up almost 12 per cent to $8,053 and the size of center stones rose from 1.16 in 2020 to 1.25 in 2021 (just under eight per cent).

       The average lab grown engagement ring cost $4,383, up 8.6 per cent on the previous year, with the center stone weighing, on average 1.49 carats (up 11 per cent).

       Dustin Lemick, founder and CEO of BriteCo, said: "With Millennials and Gen Z taking the stage as new proposers of marriage, we are seeing traditional preferences around engagement rings are changing to reflect their values. 

       "Young people are evaluating and buying lab-grown diamonds in greater numbers, but natural or earth-mined diamonds continue to dominate."
